GAS-FIRED GAS TURBINE POWER GENERATING FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a gas-fired gas turbine power generating facility capable of enhancing power generating efficiency by reducing energy loss following gas compression of low calorie fuel gas. SOLUTION: The gas-fired gas turbine power generating facility is provided with a low pressure fuel injector 18 injecting gas fuel 1 into air before compression at a flammability limit or lower, a high pressure fuel injector 19 injecting additional fuel into a combustor at high pressure, and a catalytic combustor 20 catalytically burning unburned components in exhaust gas. Preferably, the gas fuel 1 is the low calorie fuel gas and the additional fuel is liquid fuel.
