Gas Turbine Theory - Principle of Operation and ConstructionSahyog Shishodia
This presentation tells all about basic principle behind Gas Turbine, their working, operation and construction. How they came into existence and where are they used.
Gas turbine power plants work by compressing air which is then mixed with fuel and ignited in a combustion chamber. This powers a turbine, which drives both a generator to produce electricity and the air compressor. Gas turbines have three main parts - an air compressor, combustion chamber, and turbine. They can use fuels like oil, natural gas, or pulverized coal and are used for power generation especially for peak loads or as backup. Advantages include easier fuel storage and handling as well as lower maintenance costs compared to steam plants.
Gas turbines operate using the Brayton cycle, which involves compressing air, adding heat through combustion at constant pressure, expanding the hot gases through a turbine, and rejecting heat at constant pressure. Early gas turbines had low efficiency around 17% but efficiency has increased through higher turbine inlet temperatures, more efficient components, and modifications like regeneration, intercooling, and reheating. Regeneration improves efficiency by heating the compressed air with the turbine exhaust, while intercooling and reheating involve multistage compression and expansion with cooling or heating between stages. Open cycle gas turbines exhaust combustion gases while closed cycle models re-circulate gases, improving efficiency but requiring more complex components.
