A turbine bypass pipe is provided with a bypass valve. A branch pipe branches off a cold reheater pipe between the check valve and the reheater is connected to the condenser for introducing steam flowing through the turbine bypass pipe. A control valve is arranged in the branch pipe and a controller controls the bypass valve and the control valve. When the turbine bypass line is operational in one of a start-up or an auxiliary operation of the power plant, the control valve and the bypass valve are controlled by the controller so that the quantity of reheat steam introduced into the reheater is controlled and excess or surplus steam is discharged to the condenser through the branch pipe.

摘要： A method and system for controlling water level of a drum of a heat recovery steam generator for a combined cycle power plant is provided. The combined cycle power plant includes gas and steam turbines and the steam generator for recovering heat in exhaust gases from the gas turbine and for using the recovered heat to produce and supply steam to the steam turbine. At a start up operation, the water level of the drum is lowered in advance to the plant start up operation so that abrupt rise of the water level due to swelling phenomenon of the boiler water which may result in heat losses by damping water out of the plant is prevented. Also, a gas turbine load increase is maintained at a constant level during a period in which the abrupt water level rise is expected so that the swelling phenomenon is avoided.

摘要： A fuel cell power plant comprising a fuel cell employing a molten carbonate as an electrolyte, a reformer for reforming fuel into a reactive gas to be supplied into the anode of the cell, an expansion turbine connected to a compressor, a combustor for burning a gas exhausted from the anode and introducing the combustion gas into the cathode of the fuel cell along with a gas compressed by the compressor, and a waste heat recovery system. The power plant is characterized by the provision of another combustor on the passage through which cathode exhaust gas is sent from the cathode to the turbine and a passage for leading a part of the anode exhaust gas to the combustor, whereby unburned gas, included in the anode exhaust gas, is burned with the cathode exhaust gas supplied as oxygen source so that the temperature of the turbine driving gas is raised, as a result, the overall thermal efficiency of the power plant increases.

The coal gasification plant has a low-pressure steam generator for recovering heat from the furnace wall of a pressurized fluidized bed type coal gasification furnace, and a high-pressure steam generator disposed at the outlet of the gasification furnace and adapted to recover heat from the unrefined gas coming from the gasification furnace. The composite power generating plant includes a gas turbine which uses the gas generated in the gasification plant as the fuel gas, a boiler for recovering heat from the exhaust gas of the gas turbine, and high-pressure and low-pressure steam turbines which operate with the steam generated by the boiler. The high-pressure steam generated in the high-pressure steam generator is introduced to the high-pressure steam turbine, while the steam generated in the low-pressure steam generator is introduced into the low-pressure steam turbine, thereby to effectively recover the energy.
