    摘要: In a method for operating a combustor 10 of an embodiment, before ignition in the combustor 10, a mixed gas containing oxygen is circulated through the combustor 10 as a circulating gas. Then, in an operating time from the time of ignition in the combustor 10 to the time of a rated load of a turbine, from the time of ignition until reaching stable combustion conditions allowing stable combustion, a combustion gas in which a controller 100 controls a flow rate of a fuel supplied from a fuel supply part 40 and a flow rate of an oxidant supplied from an oxidant supply part 50 to maintain the same oxygen concentration as an oxygen concentration in the mixed gas is circulated as the circulating gas.

    摘要: A combustor 20A of an embodiment includes: a combustor casing 70; a combustor liner 61 which is provided in the combustor casing 70 and combusts a fuel and an oxidant to produce a combustion gas; a pipe-shaped member 101 provided to penetrate the combustor casing 70 and the combustor liner 61; a heat-resistant glass 102 which is provided on the combustor casing side in the pipe-shaped member and closes the pipe-shaped member 101; a laser light supply mechanism 103 which irradiates an interior of the combustor liner 61 through the heat-resistant glass 102 and an interior of the pipe-shaped member with a laser light 110; and a contact prevention mechanism 104A which prevents a combustion gas in the combustor liner from coming into contact with the heat-resistant glass 102.
