Abstract:
1. A gas-turbine power generating installation including a gas turbine installed in the vicinity of an overage gas field or an oil field and generating electric power with said gas turbine by using natural gas produced in the overage gas field or accompanying gas produced in the oil field, the generated electric power being supplied to a consuming site, wherein said gas turbine is a gas turbine in which air compressed by a compressor is introduced to a combustor for combustion after being mixed with fuel, a turbine is driven by generated combustion gas, and a power generator is driven by motive power obtained from a rotary shaft of said gas turbine, said installation further includes a boosting compressor driven by the motive power obtained from the rotary shaft of said gas turbine, and the natural gas or the accompanying gas is boosted in pressure by said boosting compressor and supplied as fuel to said combustor, wherein said power generator is driven by the rotary shaft of said gas turbine through a speed reducing gear, and said boosting compressor is driven by the rotary shaft of said gas turbine through a speed increasing gear.
