摘要： A method for setting or regulating the steam temperature of the live steam and/or reheater steam, in particular under part load, in a combined-cycle power plant and a combined-cycle power plant so regulated. The power-plant has a water/steam cycle including a steam turbine, fired boiler and a means for superheating or reheating the steam generated in the boiler to form live steam or reheater steam, a gas turbine set, and a downstream heat recovery steam generator connected to the water/steam cycle in such a way that steam generated in the heat recovery steam generator is admixed with the live steam or reheater steam. Improved part-load behavior is achieved in that the steam temperature of the live steam and/or reheater steam is set or regulated by setting or regulating the steam temperature of the steam generated in the heat recovery steam generator.

摘要： A method to provide Primary Frequency Regulation to a steam turbine in a combined cycle plant that comprises storing energy in the form of internal energy of the steam contained within the piping and domes of the heat recovery boilers, and then using said energy when the power grid requires a sudden increase in output power. With the present method, the losses in power generation of the steam turbine, when said turbine is operating in the Primary Frequency Regulation mode, are reduced to a minimum. When the gas turbines in a combined cycle plant operate in PFR mode, the steam turbine reduces its output power because the gas turbines must operate below their rated power. The present method converts said decrease in output power of the steam turbine in a Spinning Reserve useful for PFR in said turbine. That is to say that the present method converts said Spinning Reserve in a rapid reserve, available after just a few seconds; if necessary, response times of less than 10 seconds can be attained. The present method introduces several novel steps, which constitute its essence, said steps permitting the continuous, long term operation of the steam turbine in a combined cycle plant in PFR mode, thereby ensuring at any time the effectiveness of mains frequency regulation and also guaranteeing the stability of the power generation process in said combined cycle plant.

摘要： A process for generating power from the expansion of steam in a steam turbine system. The steam is generated by at least partially vaporizing pre-heated water by heat exchange against a first fuel gas that is generated exothermically. The at least partially vaporized water is then heated to produce the steam by heat exchange against expanded combustion product gas that is generated by the combustion of a second fuel gas in the presence of compressed oxygen-containing gas and the subsequent expansion of the combustion product gas. The steam is then expanded in a steam turbine system having more than one pressure stage to produce power and an expanded steam stream.

摘要： In an improved system for recovering heat from a combustion gas produced by burning wastes, the combustion gas or combustible gas produced by partial burning of the wastes subjected to dust filtration in a temperature range of 450-650null C. at a filtration velocity of 1-5 cm/sec under a pressure of from null5 kPa (gage) to 5 MPa before heat recovery is effected. The dust filtration is preferably performed using a filter medium which may or may not support a denitration catalyst. Heat recovery is preferably effected using a steam superheater. The dust-free gas may partly or wholly be reburnt with or without an auxiliary fuel to a sufficiently high temperature to permit heat recovery. The combustion furnace may be a gasifying furnace which, in turn, may be combined with a melting furnace. If desired, the reburning to a higher temperature may be performed under pressure and the obtained hot combustion gas is supplied to a gas turbine to generate electricity, followed by introduction of the exhaust gas from the gas turbine into a steam superheater for further heat recovery. The system can raise the temperature of superheated steam to a sufficient level to enhance the efficiency of power generation without possibility of corrosion of heat transfer pipes by the combustion gas or combustible gas.

摘要： In a combined cycle system having a multi-pressure heat recovery steam generator, a gas turbine and steam turbine, steam for cooling gas turbine components is supplied from the intermediate pressure section of the heat recovery steam generator supplemented by a portion of the steam exhausting from the HP section of the steam turbine, steam from the gas turbine cooling cycle and the exhaust from the HP section of the steam turbine are combined for flow through a reheat section of the HRSG. The reheated steam is supplied to the IP section inlet of the steam turbine. Thus, where gas turbine cooling steam temperature is lower than optimum, a net improvement in performance is achieved by flowing the cooling steam exhausting from the gas turbine and the exhaust steam from the high pressure section of the steam turbine in series through the reheater of the HRSG for applying steam at optimum temperature to the IP section of the steam turbine.

摘要： An organic rankine cycle system is combined with a vapor compression cycle system with the turbine generator of the organic rankine cycle generating the power necessary to operate the motor of the refrigerant compressor. The vapor compression cycle is applied with its evaporator cooling the inlet air into a gas turbine, and the organic rankine cycle is applied to receive heat from a gas turbine exhaust to heat its boiler within one embodiment, a common condenser is used for the organic rankine cycle and the vapor compression cycle, with a common refrigerant, R-245a being circulated within both systems. In another embodiment, the turbine driven generator has a common shaft connected to the compressor to thereby eliminate the need for a separate motor to drive the compressor.
