THERMAL POWER PLANT WITH A STEAM TURBINE

摘要

A thermal power plant has a primary heat supply, a steam generator, a steam turbine and an auxiliary gas turbine, wherein the primary heat supply is fluidically connected to the steam generator, wherein the auxiliary gas turbine is fluidically connected to the steam generator and is set up to keep the steam generator at a predefined minimum temperature when the primary heat supply is off-line, wherein a fan is encompassed, which fan is fluidically connected to the steam generator. A method is for the variable-power operation of such a thermal power plant, wherein the auxiliary gas turbine is brought on-line in dependence on an operating state of the primary heat supply, which is defined by the power to be provided by the latter.
