Abstract

See full text

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.
