摘要： A gas turbine steam cooled system has a high temperature portion 8 outlet steam temperature maintained to a predetermined value without a cooling steam pressure becoming lower than the pressure in the gas turbine cylinder. Steam coming from an intermediate pressure superheater 10 of a waste heat recovery boiler 2 is led into the high temperature portion 8 of the gas turbine for cooling thereof. The temperature of the cooling steam at the outlet of the high temperature portion 8 is detected by a high temperature portion outlet steam temperature detector 15, and a signal thereof is sent a lower value selector 19 via a temperature controller 11. Pressure in the gas turbine cylinder is detected by a gas turbine cylinder pressure detector 17, and pressure of the cooling steam at the high temperature portion 8 outlet is detected by a high temperature portion outlet steam pressure detector 16. A differential signal thereof is sent to a pressure controller 18. Signals from the temperature controller 11 and the pressure controller 18 are inputted into the lower selector 19, and temperature control valve 12 is controlled by the lower value thereof to be opened and closed.

摘要： The present invention relates to a steam-cooling system for gas turbine combustors in combined plants possessing a steam-cooled combustor; in order to maintain the combustor outlet steam temperature at planned values even during the starting and during the periods of load fluctuation, a steam valve 12 is opened and steam from a boiler 4 is conducted, and thereby the combustor of the gas turbine 1 is cooled, and steam recovery valve 11 is opened and this steam is returned to steam turbine 5. During the starting, steam is caused to flow from an auxiliary steam source 3, and a warming up is conducted. When the amount of steam at the combustor outlet decreases, the temperature of the temperature sensor 31 increases, and when this exceeds a planned value, a temperature regulating valve 30 is opened and steam from steam turbine 5 is extracted and is let into the cooling steam outlet side flow path 61 of the combustor. Furthermore, when the value of a pressure sensor 24 reaches a predetermined value, a bypass valve 14 is opened and steam is caused to flow to a condenser 6, and thus the necessary amount of steam is maintained within the combustor. This is all controlled by means of the controller 10, which constantly maintains the temperature of the cooling steam at planned values.

摘要： Piping support of a gas turbine steam cooled combustor is improved such that even when the piping support is damaged by combustion vibration, dropping of the piping support from the piping is prevented, so as to avoid intrusion of fractions of the piping support into turbine portion. An outer fitting member is fixed to a wall surface of a tail tube by welds. A ring is pinched inside the outer fitting member to be fixed by welds. The ring having an inner diameter slightly larger than an outer diameter of steam piping is fitted around the steam piping to be fixed by welds at three places. The steam piping is fixed to the ring, the ring is fixed to the outer fitting member and the outer fitting member is fixed to the tail tube. Thus, the steam piping is supported to the tail tube and even when the welds are detached by combustion vibration, no case of the outer fitting member dropping from the steam piping occurs.
