摘要： A combined cycle gas turbine plant and a corresponding method for operating such a combined cycle gas turbine plant, in which, during load operation of the combined cycle gas turbine plant, a water mass flow which is supplied according to the forced-flow principle to a waste heat steam generator is adjusted such that the evaporator heating surface of the medium pressure stage is oversupplied and thus a defined amount of excess water, which is heated in the evaporator heating surface but not vaporized, is discharged via the water-steam separator to a heat exchanger circuit for preheating fuel for the gas turbine.

摘要： A method for operating a waste heat steam generator, in particular one designed according to the forced flow principle, having an evaporator, through which a flow medium flows; an economizer having a number of economizer heating surfaces, and having a bypass line, which on the flow medium side is connected in parallel to a number of economizer heating surfaces. A variable that is characteristic of the heat energy supplied to the waste heat steam generator for controlling or regulating the flow rate of the bypass line is used, wherein the regulating or controlling of the flow rate of the flow medium through the bypass line takes place at the inlet of the evaporator subject to a supercooling target value. The regulating or controlling of the flow rate of the flow medium through the bypass line also takes place at the outlet of the evaporator subject to an overheating target value.

摘要： A once-through steam generator includes a combustion chamber, the walls of which comprise vertically arranged evaporator pipes connected to one another in gas-tight fashion by pipe webs, through which evaporator pipes flows a flow medium from bottom to top. The evaporator pipes are combined by upstream inlet collectors to form more intensely and less intensely heated pipe groups. A feed water supply is assigned to respective inlet collectors. At least one regulating valve regulates throttling of the mass flow of the flow medium into the evaporator pipes. To determine a control variable for the regulating valve, temperature measurement device measures outlet temperatures of the flow medium exiting the evaporator pipes. Each of the more intensely and less intensely heated pipe groups is assigned to one of the inlet collectors and to an outlet collector, and each of the outlet collectors has one of the temperature measurement devices.
