In an LM2500, where is fuel introduced?

In the LM2500 gas turbine, fuel is introduced through 30 fuel nozzles located in the combustion chamber, which is part of the Combustion and Rotor Frame (CRF). This design allows for uniform distribution of fuel within the combustion chamber, optimizing the combustion process and enhancing overall turbine efficiency. The presence of multiple nozzles ensures that the fuel-air mixture is well-mixed before ignition, which is crucial for maintaining stable combustion and minimizing emissions.

The choice of 30 nozzles represents a design feature that helps to improve performance, especially under varying load conditions, as it allows for better control of the fuel flow and more efficient combustion dynamics. Such enhancements contribute to the engine's reliability, durability, and overall thermal efficiency, which are essential characteristics for gas turbine operation.
