The hot section includes which components?

The hot section includes which components?

• A. Combustion, turbine, exhaust
• B. Inlet, diffuser, compressor
• C. Inlet, compressor
• D. Diffuser, exhaust

Answer: (C)

Hot section refers to the parts of a gas turbine where the gas is hot after fuel is burned. This includes the combustion chamber where fuel is burned, the turbines that extract energy from the resulting hot gas, and the exhaust where the gas exits. These components handle high temperatures and require special materials and cooling to cope with the heat. The inlet, diffuser, and compressor, on the other hand, are part of the cold section because air is brought in and compressed before combustion and does not experience the high temperatures. So describing the hot section as the combustion, turbine, and exhaust portion best reflects where the hot gases flow and where heat management is critical.
