What is the exhaust from the turbine section called?

• A. Combustion chamber outlet
• B. Diffuser outlet
• C. Turbine exhaust
• D. Exhaust plenum

Answer: (C)

The exhaust from the turbine section is called turbine exhaust. In a gas turbine, hot gases expand through the turbine to extract work, and the gases that exit the turbine are labeled turbine exhaust. This is distinct from the diffuser outlet (air that’s slowed and pressurized before combustion) and the combustion chamber outlet (hot gases that feed the turbine). The exhaust plenum is simply a chamber that collects exhaust further downstream, not the immediate turbine exit. So, the direct outlet of the turbine is turbine exhaust.
