Combustion and Regeneration topics include: Combustion and its mechanics, thermochemistry, entropy, equilibrium, combustor, regenerator, its types, calculations and effectiveness, atomization, pressure losses and film coefficient. The regeneration cycle of a gas turbine uses heat from exhaust gases to preheat compressed air before combustion. This process can increase the turbine's thermal efficiency by 35–40%. Steam turbines: Use the expansion of high-pressure steam to create rotational motion. Gas turbines: Use the combustion of fuel and air to drive a high-velocity flow of hot gases...

The regeneration cycle of a gas turbine uses heat from exhaust gases to preheat compressed air before combustion. This process can increase the turbine's thermal efficiency by 35–40%. Steam turbines: Use the expansion of high-pressure steam to create rotational motion. Gas turbines: Use the combustion of fuel and air to drive a high-velocity flow of hot gases through the turbine. Regeneration: In regeneration, heat energy from exhaust gases is transferred to compressed air before it enters the combustion chamber. This process reduces waste heat and saves fuel. Reheating: In reheating, the combustion gases are expanded in two turbines instead of one. The exhaust of the high-pressure turbine is reheated and then expanded in a low-pressure turbine. This increases the power output of the turbine. Related Test: Steam and Gas Turbines Practice Test: Governors / Regulators and Performance Show less
