Abstract:

La pile à combustible (PAC) est connue depuis longtemps comme un convertisseur d’hydrogène en énergie (électrique + thermique) possédant de très bons rendements, les recherches sur cette technologie se développent partout dans le monde de manière considérable. Les raisons sont bien connues: la réponse aux contraintes environnementales, aux problèmes posés par la production centralisée d’électricité, la nécessité d’avoir des alternatives énergétiques (vecteur hydrogène) et certaines exigences technologiques spécifiques telles que les applications spatiales, sous-marines, électroniques portables, alimentation électrique de sites isolés et de microsystèmes. Il est certain que nous assisterons dans les prochaines décennies à l’émergence de la filière hydrogène dans notre vie quotidienne comme vecteur énergétique. Le choix de la technologie des piles à combustible à membrane échangeuse de protons (PEMFC) est implicite vu les performances intéressantes (faible poids, robuste, électrolyte solide, démarrage rapide, large gamme de puissance de 1 W à10 MW, etc.). Il est donc important de pousser encore plus loin les efforts de recherche/développement autour de cette technologie pour pouvoir la maîtriser et étendre son application. Cet article présente les résultats de la modélisation de la cinétique électrochimique et la production électrique des piles à combustible PEMFC alimentée directement en gaz pur (hydrogène et oxygène) et la validation expérimentale grâce à une base de données établie au niveau du ‘’Laboratoire d’Hydrogène en Réseau – CDER‘’, dans le but d’exploiter et d’améliorer les modèles électrochimiques existants.

Abstract:

In this study, an ISO 5660-1 cone calorimeter experiment was conducted to examine the effects of changes in flow and thermal thickness around solid combustibles on heat release rate characteristics. Polymethyl methacrylate (PMMA) is a solid combustible material that does not generate char during the combustion reaction. Hence, it was selected for the experiment, and the thermal penetration depth was calculated to distinguish the thermal thickness of PMMA. Furthermore, the thermal decomposition characteristics were analyzed by measuring the heat release rate measured during the combustion of PMMA. This was performed after generating the forced flow around the combustibles by setting the duct flow of the cone calorimeter to 12, 24, and 40 L/s. The results confirmed that the thermal release rate of the thermally thin combustible material was not significantly affected by the change in the surrounding flow. Hence, the thermally thick combustible material was significantly affected by the change in the flow rate.

Abstract:

This study presents the results of a seasonal municipal solid waste composition campaign, that took place over the period of September 2017 to June 2018 in the capital city of Kazakhstan, Astana. Four sampling campaigns were conducted in order to identify the seasonal variation of municipal solid waste composition, recyclables and energy potential materials, such as combustible fraction, useful for the evaluation of waste-to-energy potential. The combustible fraction was analysed for thermal fuel properties, such as proximate and elemental analyses and gross calorific value. The results over the four different seasons showed that the average recyclable fraction of municipal solid waste on a wet basis of 33.3 wt.% and combustibles fraction was 8.3 wt.%. The largest fraction was the organics (47.2 wt.%), followed by plastic (15.4 wt.%) and paper (12.5 wt.%). Small seasonal variations were observed for organics, paper, plastic and glass fractions. The highest values were found in summer for the organic waste, in spring for paper and plastic and autumn for glass. The recyclables fraction showed an absolute seasonal variation of 5.7% with a peak in the winter season (35.4%) and the combustibles fraction showed a seasonal variation between 8.3 wt.% to 9.4 wt.%. Finally, the average calorific value of the combustible fraction was estimated to be 21.6 MJ kg-1 on a dry basis.

Abstract:

Abstract The combustion process is described and analysed based on the experimental results in the context of building fire safety. Data are obtained by means of five standard methods: ISO 5657 ignitability test, ISO 5657 cone calorimeter, ISO 9705 room corner test, EN ISO 1716 small calorimeter, and EN ISO 1182 small furnace. Various categories of building products were tested: cellulose based products (particle boards, plywoods), solid wood, floor coverings, concrete, ceramics, insulations (thermal and/or acoustic), boards (wall/ceiling), mortars, adhesives, and thin coatings. The studied products exhibited very different fire properties from non-combustible to easily combustible. In order to more effectively differentiate non-combustibles and combustibles within building products, the modified heat of combustion was calculated using all test results according to EN ISO 1716 and EN ISO 1182. The revision of criteria for Euro class A1 and A2 is proposed to obtain more realistic reaction-to-fire evaluation. In conclusion, it is advised to use single limit for heat of combustion for A1 and A2 Euro class. The proposed approach for modified heat of combustion is a convenient tool for the fast and cost-effective initial test method for non-combustibility evaluation and seems to be the proper method for distinguishing between non-combustibles and combustibles within building products. It is a better reflection of the real physical process of combustion than the current one. The third A1 criterion is questionable, regarding time to auto-ignition in EN ISO 1182 cylindrical furnace. The measurement for gross heat of combustion by EN ISO 1716 method is proposed for all Euro classes of building products with different limit values.

Abstract:

The heat release rate (HRR) of fire for solid combustibles, consisting of multi-materials, was measured using the ISO 9705 room corner test, and a computational analysis was conducted to simulate the fire using an HRR prediction model that was provided by a fire dynamics simulator (FDS). As the solid combustible consisted of multi-materials, a cinema chair composed primarily of PU foam, PP, and steel was employed. The method for predicting the HRR provided by the FDS can be categorized into a simple model and a pyrolysis model. Because each model was applied and computational analysis was conducted under the same conditions, the HRR and fire growth rate predicted by the pyrolysis model had good agreement with the results obtained using the ISO 9705 room corner test.

Abstract:

This study proposes a new high-irradiation ignition test method for studying the pyrolysis and ignition of solid combustibles under extreme scenarios (> 0.1 MW?m-2). The irradiation system that generates a 10-cm octagonal spot of dynamic irradiation with a peak flux of 1.25 MW?m-2 and 95% uniformity, and a chamber with well-controlled ambient conditions and advanced diagnostics coupled with a multi-physical parameter measurement system. A verification test was conducted on corrugated cardboard using the proposed test method, resulting in high-quality outcomes with lower coefficients of variation compared to previous test methods. This improved approach provides a better procedure for testing and understanding the ignition threshold of combustible materials and laying the foundation for the development of advanced models of material pyrolysis and ignition processes under high irradiation.

Abstract:

The population density of cities has been increasing with time and the development of industry. Building fires in large cities with high population density cause extensive human and property damage. To prevent such damage, the characteristics of flames such as the thermal radiation and intensity of the fire source must be considered when designing building structures. However, the consideration of these factors is practically inadequate. Accordingly, in this study, when a mattress was ignited in an open environment at a different installation height (0–515 mm), the measurements from a heat flux meter and the calculated thermal radiation were compared, and a comparative analysis was conducted using the existing prediction formulas by researchers described in ISO 24678-7. We examined the fire risk of mattresses according to the mattress installation height. As a result, the fire risk of the mattress was confirmed according to the mattress installation height; upon comparing the experimental and calculated values for radiant heat, it was found to be necessary to estimate the radiant heat using a calculation method that applies the configuration factor differently depending on the change in the flame shape. In addition, as a result of substituting the experimental value into the calculation method of ISO 24678-7 (a method for estimating the radiant heat of liquid combustibles), the experimental value and the calculated value were found to be significantly different. Therefore, similar to ISO 24678-7 for the radiation heat estimation method for “liquid combustibles”, an international standard for establishing the radiation heat estimation method for “solid combustible materials” as a standard was also required for a reasonable analysis of the fire safety phenomenon of solid materials, such as bed mattresses.

Abstract:

Bio mass was the fuel used for combustion and produce thermal energy. Gasification was a thermo chemical process it convert solid fuel into gaseous fuel. Gasification is the operation used to produce the combustible gas by burning solid biomass, that combustible gas is also named as producer gas. We are using downdraft gasifier to generate producer gas, why because the down draft gasifier produce a lesser amount of tar content and minimum pressure drop. In our country, large amount of solid waste like coconut shell, groundnut shell, carpentry wastage, bagasse this kind of waste is easily combustible biomass. So we can use that combustible waste to run the down draft gasifier to produce the producer gas. We have fabricated the down draft gasifier with 3.5kW power generation. Performance of gasifier has been analysed in-terms of different zone temperatures and pressure drop, wood consumption this things would be experimentally investigated.

Abstract:

In the general case, substandard combustible minerals include on-balance and off-balance reserves of primary energy materials - coal and peat deposits (solid combustible minerals) and oil and natural gas deposits (liquid and gaseous combustible minerals), which by physico-chemical, energy or geological-spatial conditions do not meet the economic criteria for extraction and use of traditional technological methods, as well as the potential of methane from coal deposits, arrays of man-made carbon-containing materials such as waste from coal mining, coal beneficiation, refining, etc. Review of the available reserves in terms of the use of modern technologies of environmentally friendly conversion can significantly expand the opportunities for the development of all types of combustible minerals in Ukraine. The paper considers the geological zoning of oil and gas fields and deposits of solid combustible minerals, as well as their reserves and production. It is shown that the reserves of the main primary energy resources in Ukraine many times exceeds the extraction and has significant opportunities to increase due to the use of substandard combustible minerals. The principles of ecologically safe conversion of substandard combustible minerals in terrestrial and underground conditions are presented. The importance of energy utilization of methane from coal deposits, arrays of such man-made carbon-containing materials as coal mining waste, coal beneficiation, oil refining, etc. was noted. The main mining-geological and technological criteria that contribute to the development of coal seams by underground gasification are given, as well as deposits and areas of coal basins of Ukraine that are suitable for underground gasification.

Abstract:

Solid waste management is commonly seen in Nigeria as simply pick up the waste and go dump it in a hole somewhere. Hence the current major solid waste management method in Nigeria is disposal at dumpsite. The solid waste management practice at the dumpsite is simple. The waste disposal trucks drive into the dumpsites through the access roads and dump their waste. Other vehicles that deliver waste to the site simply dump their waste indiscriminately by the road sides. The workers at the dumpsites use shovel to manually push the waste from the road and try to spread them as much as their strength can go. Thereafter, open air incineration without pollution control is carried out on the waste for volume reduction. This is not sustainable as it does not bring financial return at the end point of the waste. Therefore incineration with pollution control and energy recovery that will bring financial returns at the end point of the waste is ineviTable for sustainable solid waste management. In the work reported in this paper a study and preliminary design for incineration with energy recovery has been carried out. A review of solid waste component in Benin metropolis was carried out to determine the proportion of combustible material in the waste streams in the metropolis. Several conceptual designs were developed and one was selected. Detail design of a prototype for 15kW electrical power generation was done. The result obtained showed that about 43% of combustible commercial solid waste and about 16% of combustible domestic solid waste are generated in Benin metropolis. The result also showed that about 72Kg/s of combustible municipal solid waste is required for the generation of about 15kW of electrical power and the exhaust gas can be used for other process systems such as systems for drying agro-produce.

Abstract:

Waste management is a massive issue in India, most of the present systems cannot manage waste on a scalable level, thus creating pressure on the ecosystem. Before the elimination of waste, segregation needs to be done to manage individual types of waste. Hence taken the same approach to solving the problem, which most of the present-day systems fail to do. The goal is to segregate the garbage generated in individual households into solid, liquid, biodegradable, non-biodegradable, combustible, and non-combustible, using many subsystems that involve electro pneumatics, compression, and storage. Image processing techniques will further advocate the process. The desired system will further reduce the waste of an in-built pulverizer. After conducting in-depth research on the present solutions for the urban waste processing chain, the level of complexity increases as the waste goes further along the chain and, in the end, the only option left is incineration was figured out. The solution allows endpoints of the chain to process different types of garbage in a more organized fashion. Municipal solid waste (MSW) is solid waste that results from municipal community, commercial, institutional, and recreational activities. This paper aims to segregate the MSW generated by households into biodegradable, non-biodegradable, combustible, and non-combustible.

Abstract:

Based on analysis of municipal solid waste (MSW) in Shanghai city, a related integrated treatment process of MSW was studied. MSW was classified into organic, combustible, recyclable and other parts. The designed integrated treatment process includes mixed waste sorting, anaerobic digestion of the biodegradability organic waste, RDF production systems of combustible waste and deodorizing system. Organic MSW is digested under anaerobic conditions and produce biogas for power generation for electricity plant. The residue can be used to prepare organic and inorganic fertilizer; Combustible MSW has low water, high calorific value and can be prepared RDF; The recyclable trash (plastic, metal) are on sale. Other MSW is land filled. The designed integrated treatment process may provide a route to solve the problems of MSW in Shanghai.

Abstract:

AbstractFor selecting the most efficient treatment method of hospital waste, the composition analysis is generally considered to be the fundamental information. Currently, there are few studies regarding the characteristics of hospital waste. This study evaluated the physical and elemental composition of the hospital waste at the National Taiwan University Hospital (NTUH). The results should help us design an incinerator for the treatment of infectious waste, plastic syringes, pathological waste, and kitchen waste. During the study period, the estimated daily waste generation rate at NTUH was 4,600 kg/day, which consisted of 4,100 kg/day noninfectious refuse, 340 kg/day infectious waste, 70 kg/day kitchen waste, 50 kg/day pathological waste, and 40 kg/day plastic syringes. The NTUH waste consisted of 99.02% combustible wastes and 0.97% noncombustible wastes by mass. The combustibie wastes constituted paper (16.17%), textiles (9.77%), cardboard, wood, and leaves (1.12%), food waste (21.5 1%), and plastics (50.45%). The noncombustible waste included 0.40% metal and 0.57% glass. Furthermore, the analysis indicated that the wastes contained 38% moisture, 4% ashes, and 58% solid with an average heat value of 3,400 kcal/kg. From the elemental analysis, the dominant elements were found to be carbon (34%) and oxygen (15%).

Abstract:

The installation of food waste disposers has been prohibited in South Korea, due to conflicts with governmental policies that are focused on resource recovery from food waste and concerns about potential damage to the city’s sewer system. However, there is a growing demand for such systems in the country. This study proposes a system for the collective recovery of solid resources from food waste tailored for apartment complexes in South Korea, using an innovative solid–liquid separation technology. In the pilot experiment, 49.60% of the solids fed into the system were recovered as solid matter, confirming its practical applicability. Ultimately, a solid resource collective recovery system suitable for the high-rise apartment residence style of South Korea was developed and applied to an actual apartment complex. The final-stage solids were discharged from the system and processed through bio-drying, subsequently exhibiting a combustible material content of 67.06%, higher heating value (HHV) of 4843 kcal/kg, and lower heating value (LHV) of 3759 kcal/kg; moreover, they have the potential to be repurposed as biomass–solid refuse fuel (bio-SFR), compost, feed, and substrate for biogas production. The proposed food waste disposal system not only aligns with governmental policies, but also facilitates the recovery of high-quality resources from food waste, while providing a sustainable waste management solution.

Abstract:

Landfill mining is an innovative way to minimize environmental pollution, secure land and airspace, and recover secondary raw materials from landfills. The study examined the characteristics of landfilled waste at the Kumasi landfill and its potential for resource recovery. Samples were collected based on the deposition age and characterized in the laboratory. Characteristics determined were composition, volatile solids, moisture content, and heavy metal concentrations. The results indicated that the most significant recoverable resources were Decomposed Organic Materials (organic waste mixed with sand and papers) and combustibles (plastics, wood, and textile), constituting 44 % and 36 % by weight, respectively. The composition of the landfill waste was found to be influenced by the components of waste initially disposed at the landfill and its subsequent age of deposition. The metal content concentration was, however, independent of the age of deposition. The results indicate that a landfill mining project at the Kumasi landfill will make available about 89 % of the landfill volume and airspace for reuse. However, the DOMs recovered may not be suitable for application as compost on agricultural soils due to the high zinc concentrations unless applied to zinc-deficient soils. It may, however, be used as construction material in earthworks and as cover materials at landfill sites. The combustible component can be combusted to generate heat for producing hot water for hospitals, hotels, and old age care facilities.

Abstract:

The use of municipal solid waste as a raw material for alternative fuel is a promising direction for waste recycling and substitution of solid fossil fuels. Therefore, selecting of fuel composition and studying of its properties is an urgent task. The aim of this work is thermal characteristics analysis of the combustible components of municipal solid waste, which are the most common in Ukraine, for further selection of a fuel composition that will satisfy the consumer's requirements. The goal is achieved by studying the thermal destruction of samples by thermogravimetry and differential thermal analysis when materials are heated to 1000 ºС in the presence of air oxygen. Paper, cardboard, plastic, biodegradable film, textiles, leather, wood were investigated in this work. The most important results are the received data on the characteristic temperatures of destruction stages, content of water, organic and mineral substances, ash, as well as the calculated values of rate and conditional thermal effect of decomposition of organic substances. Strong formation of gaseous substances was registered for samples of polyethylene and biodegradable film, polyethylene terephthalate and cotton fabric. These features should be considered in the technologies of production and combustion of fuel. The significance of the results also lies in the fact that it is recommended to use data on the thermal stability of materials in order to prevent their ignition during drying when developing fuel production technology. In addition, the calculated values of the conditional thermal effect made it possible to evaluate the thermal characteristics of the studied materials as components of solid alternative fuels.

Abstract:

Biodiesel is obtained by transesterification of animal and vegetable triglycerides (fats), and have several advantages over fossil fuel, perhaps the most important being its renewable source and its lack of pollutants such as aromatic and sulfur components. However, biodiesel from vegetable sources such as Soya beans is expensive, and it raises the question of planting for combustibles not for food. The most interesting alternative source for biodiesel is the non expensive waste cooking oil, WCO, which also brings the obvious benefit of transforming a severe pollutant into a green combustible. WCO consists of the triglycerides, but also contains left over food solids, which must be removed by filtration, mono and diglycerides, which are the source of the WCO free fatty acids (FFA), which must be converted to esters before the transesterification of the triglycerides, or, as usually reported, saponification of the final biodiesel mixture will occur. Several methods have been devised to deal with these drawbacks, and generally involve expensive equipment in multistage processes, which include filtration, acid catalysis for the esterification of free fatty acids, removal of the acid catalyst, a base catalyzed transesterification reaction, and, finally, the separation of the glycerol by product and purification of the biodiesel. Herein we propose a new silica gel filtering system, which in one step removes both solids and free fatty acid contents of WCO. In this new approach for biodiesel, an unmodified household microwave oven is used to speed up the base catalyzed transesterification reaction, and a useful piece of advice is given for the easy follow up of the reaction progress by thin layer chromatography.

Abstract:

The first radionuclide vector (RV) for characterization of operational solid radioactive wastes (SRW) of Chornobyl Nuclear Power Plant (ChNPP) according to the IAEA methodology was established in 2018 and consisted of a set of scaling factors (SF), which have never been refined and updated, as it is recommended to be done from time to time. In this work, verification algorithm of previously established SF values, provided for by RV setting technique, was tested, and their values were updated with taking into account the implementation of a new approach for sorting ChNPP SRW into the streams. It was established that for such nuclides as 90Sr, 94Nb and 241Am, geometric mean values of SF or correlation function (CF) established on the basis of regression analysis of logarithms of nuclide content, can be used. For the other radionuclides (14С, 3Н and 235, 238U), whose activity levels were higher than the minimum detectable activity (MDA), arithmetic mean values of SF only can be used. For uranium isotopes 235, 238U, a high degree of correlation between their content is observed in all SRW materials, regardless of whether they belong to combustible or non-combustible operational waste of the ChNPP. According to the test results (testing for significance of difference under the null hypothesis) using the Student’s t-statistics, it was established that the same SF values can be applied to the waste temporarily stored in the eastern and western compartments of the ChNPP SRW repository. The waste should be separated into non-combustible and combustible materials only. This follows from the fact that combustible solid waste, if they are to be burned as it is planned, must be re-characterized using the SF value already determined for ash and by a different technique. However, until these wastes are burned, the obtained data allow estimating the expected levels of nuclide content in their ash residue.

Abstract:

The main directions of the concept of national strategies for sustainable development are considered, taking into account the problems of energy and resource saving, as well as the need for the rational use of natural and secondary resources in many countries of the world community in order to transition to a “green” economy. An assessment of the energy potential of combustible waste that has not found technological application is given as one of the priority areas in the field of nontraditional energy. The paper presents aspects of research into obtaining and production of multicomponent solid fuels. A technology is described for briquetting wet mixtures with the addition of various binders, including various combustible wastes, in order to obtain solid fuel. The features of the fuel frame formation are given, taking into account the factors affecting the performance of the briquetting plant, as well as achieving the optimal density of the briquette. A qualitative assessment was made with respect to various ratios of the components of briquetted fuel, at which the best production and consumer indicators are achieved. The features of the preparation of materials and the technological equipment used as part of the preparation and briquetting line are considered. The practical aspects of the production, drying, use of briquetted solid fuels are outlined in the paper. The paper presents studies of the energy and physico-chemical characteristics of multicomponent fuel compositions using various research laboratory equipment and methods. The proposed algorithm for solving the problem makes it possible to rationally use substandard combustible production waste to obtain multicomponent solid fuel, while energy and environmental aspects are taken into consideration at the production stage.

Abstract:

Waste to energy options can present an opportunity for effective waste management and addressing the energy crisis. This study aimed to produce Refuse Derived Fuel (RDF) from combustible Municipal Solid Waste (MSW), primarily plastics and paper. Cylindrical briquettes were manufactured from shredded raw materials using a screw extruder. The study examined the energy content, physical properties, and proximate analysis of the produced RDF. The briquettes exhibited a high calorific value of 6,736 Kcal/kg. Experimentation on briquette combustion was conducted in a pottery kiln in Thimi, Bhaktapur, revealing that RDF outperformed fuelwood both in terms of quality and quantity. The RDF shows promising potential due to its high calorific value and favorable combustion properties when supplied with air. However, the study recommends further analysis of the combustible characteristics of MSW.

Abstract:

In this study, a series of ISO 5660-1 cone calorimetry experiments were performed to understand how the heat release rate (HRR) and CO emission are affected by the thermal thickness and charring properties of solid combustibles. To this end, HRRs and CO emissions measured from burning Douglas-fir wood (which produces a charring layer during combustion) and poly methyl methacrylate (PMMA) (which does not produce a charring layer) in the ISO 5660-1 cone calorimetry experiments were compared. Relative to PMMA, Douglas-fir wood produced a lower rate of heat release and CO emission, helping lessen human damage in fires. Results obtained from the ISO 5660-1 cone calorimetry experiments clearly demonstrate that the heat release rate varies depending on the thermal thickness and the presence of charring layer within solid combustibles. Unlike PMMA, the charring layer developed for Douglas-fir wood during combustion further increases the thermal thickness, reducing the amount of thermal decomposition and the heat released from fire. The cone calorimetry experiment results also indicate that increases in charring properties of solid combustibles were directly correlated with reductions in the HRR and increases in the CO emission.

Abstract:

The heat transfer rate to a thin solid combustible from an attached diffusion flame, spreading across the surface of the combustible in a quiescent, microgravity environment, was determined from measurements made in the drop tower facility at NASA-Lewis Research Center. With first-order Arrhenius pyrolysis kinetics, the solid-phase mass and energy equations along with the measured spread rate and surface temperature profiles were used to calculate the net heat flux to the surface. Results of the measurements are compared to numerical solution of the complete set of coupled differential equations that describes the temperature, species, and velocity fields in the gas and solid phases. The theory and experiment agree on the major qualitative features of the heat transfer. Some fundamental differences are attributed to the neglect of radiation in the theoretical model. A scale analysis is developed that makes use of the experimental data at different ambient conditions to support the notion that radiation is important and to investigate the effect of pressure on the spread rate.
