Which component is NOT typically associated with gas turbines?

A boiler is not typically associated with gas turbines because gas turbines operate on a different thermodynamic cycle compared to steam turbines, which utilize boilers to convert water into steam. The primary purpose of a gas turbine is to convert the chemical energy in fuel into mechanical energy through combustion and the expansion of gases, which directly drives the turbine.

In gas turbine systems, the combustor is essential as it is where the air-fuel mixture is combusted to produce high-temperature, high-pressure gas that drives the turbine. A generator often accompanies gas turbines in power plants to convert mechanical energy into electrical energy. A recuperator serves to improve the efficiency of gas turbines by recovering some of the waste heat from the exhaust gases, which is typically used to preheat the incoming air.

Since gas turbines do not require the steam-generating function of a boiler, that component is not part of their typical setup.
