摘要： A method for operating a recirculating waste heat steam generator is provided, in which in a pressure stage of the recirculating waste heat steam generator, the feed water mass flow is guided on the basis of a specified desired value in order to control the water level in a drum. The method should give a recirculating waste heat steam generator a particularly high degree of efficiency and simultaneously a particularly high level of operational flexibility. For this purpose the thermal input introduced into an evaporator of the pressure stage is used as input variable in the determination of the desired value.

摘要： A steam turbine plant has a steam turbine and an inlet steam collection line with an inlet steam collection line segment is provided. The inlet steam collection line supplies a steam consumer and is introduced into outlet steam flow of the steam turbine at an inlet steam introduction point of the inlet steam collection line segment. A supply steam device has a switching armature for connecting the supply steam device to the inlet steam collection line segment upstream of the inlet steam introduction point. The armature is triggered and switched such that if outlet steam pressure in the inlet steam collection line segment is lower than target pressure, the inlet steam collection line segment is connected to the supply steam device for conducting steam and disconnected between the armature and the inlet steam introduction point, otherwise the supply steam device is separated from the inlet steam collection line segment.

摘要： A method of controlling a heat recovery steam generator (HRSG) includes measuring a first regulated output of the HRSG and a second regulated output of the HRSG. The method includes comparing the first regulated output to a first setpoint defining a first target output to generate a first error signal and comparing the second regulated output to a second setpoint defining a second target output to generate a second error signal. The method also includes generating, by a controller implementing a multivariable control algorithm having as inputs the first error signal and the second error signal, control signals to control the HRSG to adjust values of the first regulated output and the second regulated output.

摘要： An apparatus and method for steam cooling a gas turbine. An intermediate-pressure drum 106 of a recovery boiler supplies outlet steam, as a cooling steam, to a combustor 117 through a steam channel 116. The flow rate of steam guided into the combustor 117 is adjusted through opening or closing of a first flow control valve 120 by a controller 125 such that the pressure of the intermediate-pressure drum 106 becomes a set value set according to a load status of a gas turbine 101. A required amount of steam according to the load status of the gas turbine 101 is fed to the combustor 117. Thus, the flow rate of steam guided into the combustor 117 is controlled by adjustment of the existing first flow control valve 120 for maintaining the pressure of the intermediate-pressure drum 106 in a predetermined state, without the need to provide an expensive valve device in the steam channel 116.

摘要： A gas and steam turbine plant has a gas turbine producing exhaust gas, a water-steam loop in which water is preheated at a given high pressure and subsequently evaporated, a steam turbine in the water-steam loop, and a steam generator through which the exhaust gas flows for generating steam for the steam turbine. The steam generator has at least one preheater connected to the water-steam loop and a high-pressure heater connected downstream of at least one preheater. The water-steam loop has a partial loop connected parallel to the at least one preheater outside the steam generator for carrying an adjustable throughput quantity. A heat exchanger is disposed in the steam generator in the vicinity of the at least one preheater for removing usable heat. A method for operating the plant includes preheating a partial quantity of the water to be preheated outside the steam generator at the given high pressure, and adjusting the partial quantity as a function of an available total water quantity and admixing the partial quantity with the water preheated in the steam generator.
