GAS TURBINE FACILITY

摘要

A gas turbine facility 10 of an embodiment has a combustor 20 combusting fuel and oxidant, a turbine 28 rotated by combustion gas exhausted from the combustor 20, a heat exchanger 25 cooling the combustion gas from the turbine 28, a pipe 46 guiding a part of the combustion gas to the combustor 20 via the heat exchanger 25, and a pipe 45 exhausting a remaining part of the combustion gas to an outside. Further, the facility has a pipe 40 supplying fuel to the combustor 20, a pipe 41 supplying oxidant to the combustor 20 via the heat exchanger 25, and a pipe 42 branched from the pipe 41, bypassing the heat exchanger 25, and coupled to the pipe 41, so as to introduce the oxidant into the pipe 41.

主权项

1. A gas turbine facility, comprising:
a combustor combusting fuel and oxidant; a turbine rotated by combustion gas exhausted from the combustor; a heat exchanger cooling the combustion gas exhausted from the turbine; a working fluid supply pipe guiding a part of the combustion gas as working fluid to the combustor via the heat exchanger; an exhaust pipe exhausting a remaining part of the combustion gas to an outside; a fuel supply pipe supplying fuel to the combustor; an oxidant supply pipe supplying the oxidant to the combustor via the heat exchanger; and an oxidant bypass supply pipe branched from the oxidant supply pipe, bypassing the heat exchanger, and coupled to the oxidant supply pipe at a position between the heat exchanger and the combustor, so as to introduce the oxidant into the oxidant supply pipe.
