What unique feature does the diffuser of a gas turbine generator have?

• A. It acts as a fuel filter
• B. It also serves as the GTG mount
• C. It is a cooling component
• D. It regulates fuel flow

Answer: (B)

The diffuser of a gas turbine generator plays a crucial role in managing the airflow and pressure within the system. One of its unique features is that it serves as a mounting point for the gas turbine generator itself. This dual purpose integrates structural stability with functionality, providing a secure base while also contributing to the overall efficiency of the gas turbine operation. The design of the diffuser helps to convert kinetic energy from the exhaust flow into pressure energy as the air expands and slows down, which is essential for optimal fuel and air mixing in subsequent stages of combustion. In contrast, while a fuel filter may be part of the fuel management system, the diffuser does not perform this function. It also does not directly regulate fuel flow, nor is it specifically a cooling component, though proper air management can influence cooling in the overall system. Therefore, the aspect of serving as a mount is what distinctly characterizes the diffuser in a gas turbine generator setup.
