ABSTRACT:
A system and method for controlling the temperature of a fuel gas. The system and method includes mixing an intermediate pressure feedwater stream from the heat recovery steam generator with a high pressure feedwater stream from the heat recovery steam generator, then using that mixture to heat the fuel gas mixture. The system and method may provide for improved control over the Modified Wobbe Index of the fuel gas, which may allow for greater variation in the composition of the fuel gas.
