METHOD FOR INCREASING THE EFFICIENCY OF GAS TURBINE GENERATOR SYSTEMS USING LOW BTU GASEOUS FUELS

摘要

An improvement in a process for operating a gas turbine system containing a compression unit, a combustion unit and an expansion unit to operate a generator, wherein a low BTU gaseous fuel is used in the combustion unit and a portion of the air from the compression unit is bled from the system so as to prevent surges in the compression unit by limiting the flow of combustion gases to the compression unit, which comprises heating the air charged to the compression unit so as to reduce the volume of air from the compression unit that is bled from the system, and thereby increase the efficiency of the gas turbine system.
