Stirling engine is device generating mechanical energy without combustion fuel inside cylinder. This fact allows to supply engine from any power source. Example of such energy source can be solar radiation, combustion low-calorie carbon in outside combustion chamber or waste heat from other device like combustion engine mounted in bus or lorry. Use that kind of device in car allows to reduce fuel consumption through increase of efficiency of utilization thermal energy produced in combustion engine. The paper presents commercial solution of Stirling engines powered by waste energy and project of conceptual Stirling engine type alpha powered by flue gases from truck. The initial analysis results of hydraulic resistance in that engine have been also included.

Abstract The purpose of this article is to present the possibilities of coal shale combustion in furnaces with bubbling fluidized bed. Coal shale can be autothermally combusted in the fluidized bed, despite the low calorie value and high ash content of fuel. Established concentrations of CO (500 ppm) and VOC (30 mg/m3) have indicated a high conversion degree of combustible material during combustion process. Average concentrations of SO2 and NOx in the flue gas were higher than this received from the combustion of high quality hard coal, 600 ppm and 500 ppm, respectively. Optional reduction of SO2 and NOx emission may require the installation of flue gas desulphurization and de-NOx systems.

One potential bioenergy that has not been explored to its full is the bioenergy potential of wood processing industry waste. The wood processing industry’s waste from saw mill wood is an alternative fuel substitute for IDO or MFO which has been widely used in the wood processing industry. The calorific value of saw mill wood waste is around 2,600 -3,400 kcal / kg, because there are many cellulose, sulfur, lignin, water biomass and so on. If the use is burned, it will directly give potential environmental impacts in the form of emission gas pollution in the form of Fly Ash, CO2, NOx and CxHy. This method is considered less efficient and gives less value. This study aims to obtain renewable energy sources by converting sawmill wood solid fuel wood processing industry into clean, sustainable and high-calorie gas fuel (syngas) as well as preventing air pollution. The method used is the development of gasification process technology in the burner vesel fluidized bed reactor with a controlled, low oxygen vertical perforated blade installation, resulting in Syngas. Through the gasification process, saw mill wood waste can be converted into gas that is more flammable with higher calorific value and environmentally friendly (clean energy). Syngas technology will be designed based on the principle of imperfect / oxygen-poor combustion at temperatures of 300 – 500°C, inside the closed vesel, so that the gas formed is CO, H2 and CxHx gas. The output is the development of gasification process technology that produces bioenergy syngas can be used in the substitution of boiler fuel for an environmentally friendly wood drying process.

The problem of the effective use of traditional energy sources and the search for alternative resources is currently urgent. Today, in Ukraine, the low-calorie gas potential, which in large quantities is formed in landfills from solid household wastes, in particular biogas, is almost not used. The number of existing domestic installations for the disposal of this gas is insignificant. Today, this valuable resource in quantities of up to 1 billion cubic meters per year is emitted into the atmosphere contaminating it, or burned in flares. Rarely biogas is used in automotive internal combustion engines. However, replacing gasoline with biogas results in reduction in engine power and an increase in fuel consumption. Knowing the component composition of biogas, one can calculate the heat of its combustion and the heat of combustion of gas-air mixtures.
According to the results of analytical studies, the graphic dependences of the change in effective power, torque and the effective specific biogas flow rate on engine revolutions were constructed and a comparison of these values with those of a petrol engine was performed. Dependencies show that the use of biogas as a fuel for the ICE leads to a significant reduction of the above parameters: in particular, the effective power decreases to 20%, torque to 22%, and the specific effective fuel consumption increases by 170%. However, due to the low cost of this type of automobile fuel and the considerable resource base for its obtaining in Ukraine, one can conclude - the use of biogas from landfills should be expanded and this is promising, in terms of energy independence of both separate economic entities and the state as a whole.

To determine the efficiency of biogas use in the existing industrial enterprises of the metallurgical industry of Ukraine and Zaporizhia region, in particular, the basic economic indicators of conversion of standard furnace equipment to biogas mixtures from various derivatives and sources available in the region are calculated. The technical feasibility and economic feasibility of using biogas mixtures as an alternative fuel for energy supply of thermal and heating furnaces of industrial enterprises on the example of a real object are determined. It is shown that to use low-calorie fuel in power equipment, taking into account its quality indicators, it is expedient both separately and in combination with traditional energy sources. It is revealed that the economic indicators of projects for the introduction of biogas technologies at metallurgical enterprises differ depending on many initial conditions, such as: sources of origin and chemical composition of biogas; characteristics of power equipment that is converted to such fuel; the proportion of natural gas substitution in the fuel mixture; etc. Based on the trend of constant growth in the cost of traditional energy resources, the introduction and use of their alternative and renewable counterparts in energy-intensive metallurgical enterprises is relevant and, with the right approach, cost-effective Keywords: energy efficiency, biogas technologies, biogas, natural gas, purification, enrichment, industrial furnaces, economic feasibility

Annotation – The analysis of scientific publications over the past ten years in the direction of creating gas ICEs in Ukraine, operating on natural gas, biogas or similar low-calorie fuels. The objectives of the work summarize the results of studies on the use of model gas in a gas internal combustion engine operating on a power plant drive. Developed recommendations on biogas additives to natural gas depending on the power plant load, and to develop a fuel control algorithm. The article provides recommendations on setting up the power system and automatic regulation of a gas engine running on a mixture of natural gas (methane) and biogas. To solve the tasks, a gas-electric installation with a rated power of 30 kW was tested. Initially, the installation was equipped with an 8-cylinder gasoline engine with spark ignition and an electric generator. The base ICE was converted to purely gas with a compression ratio of 8.5. In the physical modeling of biogas to natural gas additives in the model gas, the volume fraction of carbon dioxide increased to 30 % with a decrease in the load. By calculation, determined a similar ratio of compressed natural gas and biogas additives. For the calculation, it assumed that natural gas contains 90 ... 95 % methane, and biogas 60 % methane and 40 % carbon dioxide. The possibility of using biogas with 60 % methane as an additive to natural gas in piston ICEs with spark ignition has been confirmed. It was found that with a decrease in load, the biogas fraction increase and replace up to 85 % of natural gas. When working on biogas additives, the values of the concentrations of hydrocarbons and residual oxygen in the exhaust gases were determined to control the setting of the gas equipment of the internal combustion engine. Under operating conditions, three test modes selected for the power plant: idle, 50 % load, rated mode. The research results can serve as the basis for creating a control algorithm for the supply of biogas additives to natural gas, depending on load changes.

The methane-hydrogen fraction is a gaseous hydrocarbon by-product during oil processing for obtaining petroleum products. Until recently, the methane-hydrogen fraction was used as furnace oil in internal technological processes at a refinery. Some of the low-calorie methane-hydrogen fraction was burned in flares. Driven by the prospect of the methane-hydrogen fraction use as a fuel alternative to natural gas for burning in thermal power plants boilers, it became necessary to study the methane-hydrogen fraction combustion processes in large volumes. The conversion of ON-1000/1 and ON-1000/2 furnaces from the combustion of the methane- hydrogen fraction with combustion heat of 25.45 MJ/m3 to the combustion of the composition with combustion heat of 18.8 MJ/m3 leads to a decrease in temperature in the flame core for 100 °C as an average. The intensity of flame radiation on the radiant tubes decreases. Therefore, the operation of furnaces during combustion of methane-hydrogen fraction with a low heat of combustion at the gas oil hydro-treating unit is carried out only with a fresh catalyst, which allows lower flame temperatures in the burner.The experiments to determine the concentration of nitrogen oxides NOx and the burning rate w of the methane-hydrogen fraction in the ON-1000/1 furnace and natural gas in the TGM-84A boiler, depending upon the heat of combustion Qnr were carried out. The obtained results showed that the increase in the hydrogen content Н2 from 10.05 % to 18.36% (by mass) results in an increase in the burning rate w by 45%. The burning rate of natural gas with methane CH4 content of 98.89% in the TGM-84A boiler is 0.84 m/s, i.e. it is 2.5 times lower than the burning rate of the methane- hydrogen fraction with H2 content of 10.05%. The distributions of heat flux from the flame qf over the burner height h in the TGM-84A boiler were obtained in case of natural gas burning and calculation of burning of the methane-hydrogen fraction with a hydrogen content of 10.05% and methane of 28.27%. The comparison of the obtained data shows that burning of methane- hydrogen fraction causes an increase in the incident heat flux qf at the outlet of the burner.
