摘要： A method for operating a gas and steam turbine plant is provided. In the plant, the flue gas that escapes from a gas turbine is routed through a waste gas steam generator and where a flow medium that is used to drive a steam turbine is conducted in a flow medium circuit that includes several pressure stages. At least one of the pressure stages has an evaporator circuit with a steam collection drum that has a plurality of downpipes connected to the steam collection drum and a plurality of rising pipes downstream of the downpipes that are likewise connected to the steam collection drum and are heated by the flue gas in the waste heat steam generator. The height of the fluid column formed by the flow medium in the downpipes is monitored and a transient dry operation of the evaporator circuit can thus be detected and safeguarded against.

摘要： A method for operating a steam generator comprising a combustion chamber having a plurality of evaporator heating surfaces which are connected in parallel on the flow medium side is provided. An object is to provide a steam generator which has a particularly long service life and which is particularly reliable. For this purpose, a flow medium is introduced into an inlet of a first evaporator heating surface at a temperature which is lower than the temperature of the flow medium introduced into the inlet of a second evaporator heating surface.

摘要： A continuous evaporator for a horizontally constructed waste heat steam generator is provided. The continuous evaporator includes a first evaporator heating surface having a plurality of essentially vertically arranged first steam generator tubes through which a flow medium can flow from bottom to top, and a second evaporator heating surface which is mounted downstream of the first evaporator heating surface on the flow medium side. The second evaporator heating surface includes a plurality of additional essentially vertically arranged second steam generator tubes through which a flow medium can flow from bottom to top. The first steam generator tubes are designed in such a manner that the average mass flow density which may be controlled in the full load operation does not fall below the predetermined minimum mass flow density in the first steam generator tubes.

摘要： A method for operating a once-through steam generator including an evaporator heating surface is provided. A target value for the supply water mass flow is fed to a device for setting the supply water mass flow, which is predefined using the ratio of the heat flow currently being transferred in the evaporator heating surface from the hot gas to the flow medium to a target enthalpy increase predefined with respect to the desired live steam condition of the flow medium in the evaporator heating surface. A forced-flow steam generator used for carrying out the method is also provided. The heat flow transferred from the hot gas to the flow medium is ascertained for this purpose allowing for a specific temperature value characteristic of the current temperature of the hot gas at the evaporator inlet and a specific mass flow value characteristic for the current mass flow of the hot gas.
