Some examples of the deterioration to the turbine caused by fuel gas:
- High temperature in the compression chamber can cause distress to the blades
- Hydrocarbon liquid in the fuel gas that is not burned can ignite and create failure for the transition piece
- Back pressure built up can also cause compressor surge
In order to prevent the hydrocarbon liquid in fuel gas, it needs to be treated and have a superheat temperature of at least 500F above the hydrocarbon dew point.
