Steam and Gas Turbines Practice Test: Combustion and Regeneration
Fast practice, instant feedback. Timer auto-submits when time’s up.
Avg score: 65% Most missed: “____________ are also a part of gas turbine fuel injectors.”
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... Show more
