Résumé :
This article discusses the technology used at the John W. Turk Jr. Power Plant in Fulton, Ark., to tackle the challenges of raising the pressure and temperature of the steam to new heights. The Turk plant is the first in the United States where the final steam conditions exceed both the critical pressure and a temperature of 1,100°F. Operating as an ultrasupercritical boiler, the Turk plant has the highest net plant efficiency of any solid fuel power plant in the United States. In this plant, Southwestern Electric Power Company tapped Babcock & Wilcox to design, supply, and erect the 600-MW advanced supercritical steam generator. To best optimize efficiency, the design team selected a single reheat cycle with elevated steam pressure and temperature. Babcock & Wilcox engineers also employed computational fluid dynamics modeling to place burners and overfire air ports to make the best use of low-sulfur coal.

Résumé :
This study examines five potential improvement projects that could be implemented at the Continental Tire manufacturing plant located in Mount Vernon, IL. The study looks at insulating of tire molds, installation of variable frequency drives on circulating pumps, pressure reduction turbines, waste heat utilization used for absorption cooling, and cogeneration using a gas turbine cycle. A feasibility study and cost analysis was performed for each project to determine recommendation for implementation. The two most appealing projects are the insulation addition and the installation of variable frequency drives. Adding insulation would produce energy savings in the range of 908 kJ/s (3,097 Btu/hr) to 989 kJ/s (3,374 Btu/hr) and annual savings between $13,390 and $14,591. Installation of variable frequency drives on two 200 hp circulating pumps would produce energy savings between 74.6 kW (100 hp) and (104.6 kW (140.2 hp) with annual monetary savings in the range of $41,646 to $58,384.

Résumé :
Bibliography: leaves 132-159. Boron efficiency in oilseed rape (Brassica napua L. and B. juncea L.) was investigated in a wide range of genotypes. Using a solution culture screening of 10 day old seedlings, root length best described shoot growth response, and was used to characterise a total of 65 genotypes. Varieties and breeders lines tolerant of B-deficient growing conditions were identified, and the screening process validated through field trials. B responses in plants sampled at the 'green bud' stage indicated that vegetative growth is important in B efficiency. Studies were conducted to investigate the mechanism of B efficiency in oilseed rape. Results suggest no association between B efficiency and the capacity to acidify the root rhizosphere, or an increased translocation of B from root to shoot. Boron retranslocation was also studied as a mechanism of B efficiency.

Frantz, Jonathan M. « Determining the Factors That Control Respiration and Carbon Use Efficiency in Crop Plants ». DigitalCommons@USU, 2003. https://digitalcommons.usu.edu/etd/6600.

Texte intégral
Résumé :
In the literature on plant respiration, there are two viewpoints concerning the source of respiratory control: supply (photosynthate availability) or demand (temperature dependent) limitations. While different studies indicate the primary dependency for respiration is either the supply or demand side, the two paradigms cannot both be true. The relative importance of each paradigm may depend on a number of factors including period of time during which respiration is measured, phase of plant development, environmental conditions, and species. Studies were performed using continuous CO2 gas-exchange instrumentation to monitor short- and long-term changes in whole canopies of lettuce, tomato, soybean, and rice in response to changes in light and temperature during vegetative growth. Respiration in all crops was less sensitive to temperature than previously reported. This is likely due to large amounts of temperature-insensitive growth respiration as a fraction of total respiration during early growth. Carbon use efficiency (CUE) decreased with warm night temperatures, but the change was too small to decrease the final dry mass or carbon gain after night temperatures decreased. Canopies with constant day/night temperature had the same CUE, in elevated CO2 (1,200 μmol moJ- 1), regardless of temperature. In ambient CO2 (400 μmol mol-1), CUE decreased significantly when temperatures were above 32C. Applying shade initially decreased CUE because of low photosynthesis and high respiration. After about 12 days, canopies acclimated, based on recovery of CUE. Different species acclimated to shade to different extents, but no interaction was evident between light and shade stress. These data were used to predict changes in photosynthesis, respiration, and carbon use efficiency given light, temperature, and CO2 concentrations.

Movahedi, Mahsa. « Identifying stomatal signalling genes to improve plant water use efficiency ». Thesis, University of Sheffield, 2013. http://etheses.whiterose.ac.uk/4539/.

Texte intégral
Résumé :
Water is lost from higher plants via transpiration through stomatal pores the aperture of which is regulated by pairs of guard cells. Genetic engineering of the guard cell abscisic acid (ABA) signalling network that induces stomatal closure under drought stress is a key target for improving crop water use efficiency. In this study experiments were designed to investigate whether the biochemical mechanisms associated with the N-end rule pathway of targeted proteolysis could be involved in the regulation of stomatal apertures. The results indicate that the gene encoding the plant N-recognin, PRT6 (PROTEOLYSIS6), and the N-end rule pathway, are important in regulating stomatal ABA-responses in addition to their previously described roles in germination and hypoxia. Direct measurements of stomatal apertures showed that plants lacking PRT6 exhibit hypersensitive stomatal closure in response to ABA, and IR thermal imaging revealed reduced evapotranspiration under drought-stress. Together with a reduction in stomatal density, these properties result in drought tolerant plants. Plants lacking PRT6 are able to synthesis NO but their stomata do not close in response to NO suggesting that PRT6 is required for stomatal aperture responses to NO. Double mutant studies suggested that PRT6 (and by implication the N-end rule pathway) genetically interacts with known guard cell ABA signalling components OST1 and ABI1, and that it may act either downstream in the same signalling pathway or in an independent pathway. Several other enzymatic components of the plant N-end rule pathway were also shown to be involved in controlling stomatal ABA sensitivity including arginyl transferase and methionine amino peptidase activities. These results indicate that at least one of the N-end rule protein substrates which mediates ABA sensitivity has a methionine-cysteine motif at its N-terminus. A separate set of experiments were designed to investigate whether stomatal ABA-signalling pathways could have been conserved throughout land plant evolution. Cross-genetic complementation experiments were carried out to determine whether Physcomitrella stomatal apertures are able to respond to ABA and CO2 using a similar signalling pathway to that of flowering plants. The results demonstrated involvement of OST1 and ABI1 orthologues indicating that the stomata of the moss respond to ABA and CO2 using a signalling pathway that appears to be directly comparable to that of the model flowering plant Arabidopsis thaliana.

Résumé :
This study models the HVAC system of a power plant. It involved Computer simulations to study the energy demand by the HVAC system of the power plant as well as the energy demand of the system with modifications on the plant such as the building materials, use of energy efficient lighting, etc. Further studies on the energy demand of the system with the power plant located at different regions of the country were done to understand the effects of climate and locations. It is important to have an understanding of how a plant generating energy uses it for Heating, Ventilating and Air conditioning within the power plant building itself. This study has provided a better understanding of the energy use and how the HVAC system use in the offices and other areas located in the power plant building operates. The study included implementation of energy efficient measures in the choice of building materials for the building. The U.S. Department of Energy (DOE) EnergyPlus program was used to model the HVAC system of the power plant making use of the parameters and modified parameters of the power plant. The results of this study show that the energy demand of the HVAC system of a power plant is significantly affected by the choice of materials for the building. It was found that there is a reduction in the power demand of the HVAC system of the plant by about an average of about 21.7 % at the different the locations. It was also found that this resulted in the amount of energy saved per year of about 87,600 kWh. This gives an average cost savings per year of about $10,512.

Résumé :
Increasing concerns over the distribution, abundance and security of fresh water resources in Australia have led to a nationwide re—evaluation of their management and sustainability. The potential for reductions in municipal water use through demand management are substantial, including the potential for savings through the improved design and management of the irrigated urban landscape. It is proposed that the selection of more appropriate plant species is essential to maximising outdoor water savings. Current plant selection practices are, however, typically based upon highly questionable and potentially flawed anecdotal evidence. Ideally, these decisions should stem from detailed investigation of the water requirements, drought tolerance and water use efficiency (WUE) of specific plants. Such investigation forms the basis of this thesis. An extensive range of ornamental plant species were therefore examined, chosen based on their origin (native vs. exotic) and aesthetic function or utility in the landscape. It was hypothesised that those plants of Australian origin, due to the frequency of drought in their native habitats, would demonstrate more tolerance to water stress than their exotic counterparts. In the first of three experiments, plants were subjected to varying levels of drought stress using differential rates of irrigation, each replacing a fixed percentage of potential evapotranspirational demand. Plant recovery capacity was subsequently assessed during an extended well—watered period. A range of physiological parameters was monitored and, using digital image analysis, changes in the level of foliar display and canopy transparency were assessed as objective measures of plant ornamentality and amenity value. Development of an improved method of imposing drought stress, for use in a subsequent study, involved a separate detailed assessment of a high molecular weight polymer, polydiallyldimethylammonium chloride (PDADMAC), which demonstrated its significant potential as an osmoticum. A detailed and intensively monitored third experiment was carried out with two groundcover species, the exotic Lobularia maritima (Sweet Alyssum) and the Australian native Chrysocephalum apiculatum (Yellow Buttons), each previously revealed as having particularly high WUE and drought tolerance. Each species was subjected to one of several rates of drought stress imposition using frequent incremental additions of PDADMAC to an air-lift irrigation system followed by a period of recovery. A similar range of physiological parameters was monitored in this study, in addition to carbon isotope discrimination measurement and a microscopic examination of leaf surface morphology. There was a high level of concurrence between the studies, with the plants of Australian origin generally exhibiting superior drought resistance and higher WUE than the exotic plants examined. The native plants typically maintained higher levels of foliar display and exhibited higher net photosynthesis rates, transpiration rates and final shoot dry weights than the corresponding exotics. The natives also maintained lower overall leaf water potentials, both in the absence and presence of drought stress, possibly enabling the positive water balance in plant tissues through the creation of a strong water potential gradient between plant and soil. C. apiculatum appears to have utilised other traits and strategies for its superior performance under drought stress, including its contrasting phenology to L. maritima and its greater level of pubescence. During recovery, the natives also demonstrated a greater overall capacity for regeneration than the exotics, as measured by foliar gains. The effect of decreasing water availability was also highly consistent across the studies, with decreasing water availability producing overall declines in foliar display, foliar display—based WUE, net photosynthesis rates, leaf water potentials, final shoot dry weights, survival times and general plant health. Based upon the implications of these findings, a number of practical recommendations were developed for use in the design and management of water conserving urban landscapes.

Résumé :
Abstract In Sri Lanka, around 50% of the electrical energy generation is done using thermal energy, and hence maintaining generation efficiencies of thermal power plants at an acceptable level is very important from a socio-economic perspective for the economic development of the country. Efficiency monitoring also plays a vital role as it lays the foundation for maintaining and improving of generation efficiency. Heat rate, which is the reciprocal of the efficiency, is used to measure the performance of thermal power plants. In combined cycle power plants, heat rate depends on ambient conditions and efficiencies of subsystems such as the gas turbine, Heat Recovery Steam Generator (HRSG), steam turbine, condenser, cooling tower etc. The heat rate provides only a macroscopic picture of the power plant, and hence it is required to analyse the efficiency of each subsystem in order to get a microscopic picture. Computer modelling is an efficient method which can be used to analyse the each subsystem of a combined cycle power plant. Objective of this research is to develop a computer based tool which simulates the performance of subsystems of a combined cycle power plant in Sri Lanka. At the inception of the research, only heat rate was measured, and performances of subsystem were unknown.                  During the analysis, plant is divided into main systems, in order to study them macroscopically. Then, these main systems are divided into subsystems in order to have a microscopic view. Engineering equation solver (EES) was used to develop the tool, and the final computer model was linked with Microsoft excel package for data handling. Final computer model is executed using both present and past operating data in order to compare present and past performance of the power plant.             In combined cycle power plants steam is injected into the gas turbine to reduce the NOx generation and this steam flow is known as NOx flow. According to the result it was evident that turbine efficiency drops by 0.1% and power output increase by 1MW when NOx flow increases from 4.8 to 6.2kg/s. Further it was possible to conclude that gas turbine efficiency drop by 0.1% when ambient temperature increased by 3 C; and gas turbine power output decrease by 2MW when ambient temperature increases from 27 to 31 degrees.   Regarding the steam cycle efficiency it was found that steam turbine power output drops by  0.5MW when ambient temperature increases from 27 to 31 degrees; and steam cycle efficiency increases by 1% when NOx flow increases from 4.8 to 6.2kg/s. Further, steam turbine power output decreases by 0.25MW When NOx flow increases from 4.8 to 6.2kg/s                 Heat rate, which is the most important performance index of the power plant, increases by 10units (kJ/kWh) when ambient temperature increases by 3 C. Heat rate also increases with raising NOx flow which was 6.2kg/s in 2007 and 4.2kg/s in 2011. Hence, heat rate of the power plant has improved (decreased) by 10units (kJ/kWh) from 2007 to 2011.                Other than above, following conclusions were also revealed during the study.                         1)       HRSG efficiency has not change during past 4 years 2)     Significant waste heat recovery potential exists in the gas turbine ventilation system in the form of thermal energy

Résumé :
E911 creep samples exposed to temperatures of 600˚C, 625˚C and 650˚C at differing stress levels were supplied by CORUS. The hardness of the gauge length that experienced both creep strain and temperature was found to be lower than that of the head where thermal softening only can be assumed. The changes in the morphology and size of precipitates were observed qualitatively by optical microscopy and Scanning Electron Microscopy. A creep fracture mechanism map of E911 steel was constructed with two modes of creep (transgranular and intergranular ). A fitted ellipse shape was used to characterise the irregular block shape by Electron Backscattered Diffraction (EBSD). It showed that the width of the block inside a prior austenite grain increases more rapidly in the gauge length than in the head; subgrain growth was also observed by EBSD. Transmission Electron Microscopy studies indicate that at 600°C E911 steel can reach up to 75647 hours creep rupture life (108MPa), which is due to the relatively small size of M23C6, Laves and M2X phases. However, Z phase precipitation results in a drop in creep resistance owing to the dissolution of fine MX phase and the transformation of M2X phase. At 625°C and 650°C, the creep rupture life decreases owing to the coarsening of Laves, M23C6 and M2X phases. Four experimental steel casts were prepared with varying levels of Ni and Cr to investigate the effect of these elements on Z phase formation. After 10,000 hours exposure, there was little evidence of Z phase in the samples studied and therefore it is difficult to draw definitive conclusions about the role of Ni or Cr in promoting Z phase formation. It is possible that the casts studied here will allow better conclusions to be drawn after exposing the samples to longer durations.

Résumé :
The objective of this paper is to evaluate methods to increase the efficiency of a gas turbine power plant. Advanced intercooled gas turbine power plants are quite efficient, efficiency reaching about 47%. The efficiency could be further increased by recovering wasted heat. The system under consideration includes an intercooled gas turbine. The heat is being wasted in the intercooler and a temperature drop happens at the exhaust. For the current system it will be shown that combining the gas cycle with steam cycle and removing the intercooler will increase the efficiency of the combined cycle power plant up to 60%. In combined cycles the efficiency depends greatly on the exhaust temperature of the gas turbine and the higher gas temperature leads to the higher efficiency of the steam cycle. The analysis shows that the latest gas turbines with the intercooler can be employed more efficiently in a combined cycle power application if the intercooler is removed from the system.
