    摘要: A pressurized fluidized bed combined electricity generation system for improving gas turbine output increases and prevention of surging is provided. This pressurized fluidized bed combined electricity generation system is a combined electricity generation system including a steam turbine; a pressurized fluidized bed boiler for generating steam for supply to the steam turbine by combusting air from an air supply system and fuel from a fuel supply system; a gas turbine driven by exhaust gas such as combustion gas from the pressurized fluidized bed boiler and air; and a compressor directly coupled to the gas turbine. In addition, this pressurized fluidized bed combined electricity generation system has a first bypass duct communicating between the outlet side of the compressor and the exhaust gas side of the gas turbine and having a switching valve; a second bypass duct communicating between the outlet side of the compressor and the inlet side of the gas turbine and having a switching valve; and a control device which receives measured pressure values of a pressure detector which measures the pressure at the outlet of the compressor. This control device controls the switching valves of the first and second bypass ducts based on the relationship between the degree of opening of the inlet variable guide vane of the compressor which is determined in advance and a surge limiting pressure. A part of the steam generated by the pressurized fluidized bed boiler is extracted, mixed in with the exhaust gas or the above-mentioned air, and supplied to the gas turbine. Air from the compressor is supplied as fuel for the pressurized fluidized bed boiler.

    摘要: A combined cycle gas turbine system is improved to enhance a gas turbine efficiency and a combined efficiency by effecting steam-cooling of a combustor transition piece and a turbine blade. The combined cycle system has a gas turbine (8) having a generator (1), a compressor (2), a combustor (3), a blade cooling air cooler (4) and a turbine (6), a steam turbine (29) having a high pressure turbine (21), an intermediate pressure turbine (22) and a low pressure turbine (23), and a waste heat recovery boiler (9). Saturated water of a high pressure pump (27) is partially led into a demineralizer (118) and a water sprayer (116) for cooling steam to be supplied into a moving blade (52). The steam, after being used for cooling, is recovered into a reheater (20). Outlet steam of the high pressure turbine (21) is led into a stationary blade (53) for cooling thereof and the steam is then recovered into an inlet of the intermediate pressure turbine (22). Also, steam of an intermediate pressure superheater (16) is led into a combustor transition piece (54) for cooling thereof and the steam is recovered into the inlet of the intermediate pressure turbine (22). Thus, moving blade cooling steam is reduced and the combined efficiency is enhanced.

    摘要: A steam temperature Ts and a casing air temperature Ta are measured by thermometers. The measurement results are taken into measuring devices and converted into electric signals. The electric signal is A/D converted by the measuring device and then, is sent to a control apparatus where a difference between both the temperature is calculated by a subtracter of a processor provided in the control apparatus. When an absolute value ΔT=|Ta−Ts of this difference is contained within 10° C. continuously ten times, a control signal is sent from a computing unit to a controller which is the control section, a pressure adjusting valve and the like are controlled and a cooling medium is switched to steam.
