Gas Turbine Fuel Booster

Compressors are used in gas turbine fuel booster applications for compressing natural gas from various sources to constant discharge pressures, such as those required by natural gas fired combustion turbine-generators for generating electricity. The fuel gas booster compressors ensure continuous supply of fuel gas at specified discharge pressures to the turbine-generators, where the volume of fuel gas required is dictated by the electric power demand on the system. Many of the new natural gas fired power plants use combined-cycle units, where each unit has a gas turbine and a steam unit, all in one. The waste heat from the gas-turbine process is directed towards generating steam, which is then used to generate electricity much like a steam unit.
