WebbBrayton cycle consists of three main components namely (1) compressor (2) combustor, (3) turbine, and (4) heat exchanger (in case of the closed system) All these components undergo compression, combustion, and expansion respectively. Different kinds of fuels like oil etc. can be used as heat sources for gas turbine engines. WebbCompared with the simple Brayton cycle, Brayton cycle with regeneration can produce the same work with less heat input. Brayton cycle with intercooling, reheating, and regeneration has the highest thermal efficiency and larger work output. Also, it consumes more fuel due to reheating compared with the other two cycles.
