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 continuous steam generator is provided. The continuous steam generator includes a number of burners for fossil fuels, the outside wall thereof being fully or partially formed from steam generator tubes welded together in a gas-tight manner. The burners are arranged in a combustion chamber, and a vertical gas duct is mounted downstream of the combustion chamber above a horizontal gas duct on the hot gas side. A first part of the steam generating tubes forms a system of evaporation tubes mounted upstream of a water separator system, on the flow medium side, and a second side, and a second part of the steam generating tubes forms a system of superheater tubes mounted downstream of the water separator system on the flow medium side. Superheater tubes adjacent and parallel to evaporation tubes are mounted directly downstream of the water separator system on the flow medium side.

摘要： A fossil-fired steam generator for a steam power station includes a number of economizer, evaporator and superheater heating surfaces forming a flow path through which a flow medium flows in a plurality of pressure stages. In a high-pressure stage, an overflow line is connected to the flow path on its inlet side and leads to an injection valve disposed upstream in the flow path from a superheater heating surface in a medium-pressure stage on the flow medium side. The overflow line has two supply lines of which a first supply line branches off on the flow medium side upstream from a high-pressure preheater and a second supply line branches off on the flow medium side downstream from the high-pressure preheater.

摘要： A method is provided for regulating a brief increase in power of a steam turbine that has an upstream fossil-fired once-through steam generator having a plurality of economizer, evaporator and superheater heating surfaces which form a flow path and through which a flow medium flows. The flow of the flow medium through the fossil-fired once-through steam generator is increased in order to achieve the brief increase in power of the steam turbine. The method involves using desired enthalpy value at the outlet of an evaporator heating surface as a control variable for determining a desired value for the flow of the flow medium through the fossil-fired once-through steam generator. The desired enthalpy value is reduced in order to achieve the brief increase in power of the steam turbine.

摘要： A method is provided for controlling a short-term increase in power in a steam turbine including a fossil-fired steam generator having a flow path through which a flow medium flows. The method involves tapping off the flow medium from the flow path in a pressure stage and injecting it into the flow path on the flow-medium side upstream of a super heater heating surface of the respective pressure stage. A first characteristic value is used as a controlled variable for the amount of injected flow medium. The first characteristic value is characteristic of the deviation between the outlet temperature of a final super heater heating surface of the respective pressure stage on the flow medium side and a predetermined nominal temperature value. The nominal temperature value is reduced and, for the duration of the reduction in the nominal temperature value, the characteristic value is temporarily increased over-proportionately to the deviation.
