Development of gas turbine combustor preliminary design methodologies and preliminary assessments of advanced low emission combustor concepts

摘要: It is widely accepted that climate change a very serious environmental concern. Levels of carbon dioxide (CO2) and other emissions in the global atmosphere have increased substantially since industrial revolution now increasing faster than ever before. There thought this has already led to dangerous warming Earth’s atmosphere relevant changes around. Emissions legislations are going to be stringent as years will pass. Hydro carbon fuel cost also increasing substantially; more over non- renewable source energy. There an urgent need for novel combustor technologies reducing emission as well exploring alternative renewable fuels without effecting combustor performance. Development combustors needs comprehensive understanding conventional combustors. The design development gas turbine crucial but uncertain part engine development process. At present, process relies upon wealth experimental data correlations. Some major manufacturers addressed the above problem by developing computer programs based on tests empirical data assist designers, such proprietary. is a methodologies which would lead to substantial contribution knowledge field Developed design methodologies useful researchers preliminary design assessments gas turbine combustor. In study, step dual annular radial axial combustor, triple reverse flow been developed. Design developed could used carry out preliminary along with performance analysis combustion chambers. In study author proposed undertaken preliminary studies some concepts. A concept dilution zone less been this study. According air introduced through nozzle guide vanes provide optimum temperature traverse blades. Preliminary predicts length of shorter compared case, resulting in reduced weight, burn vibrations. Reduced eventually leads to lower emissions. Another hydrogen synthesis from kerosene reformation undertaken in work. Addition additive combustor shows large benefits engines addition to reduction NOx levels. two stages, combustion ~5% hydrocarbon occur first stage at higher equivalence ratios presence catalyst, eventually lead formation rich flue gases. subsequent the …
