摘要： A combined cycle power plant includes a gas turbomachine, a steam turbomachine operatively coupled to the gas turbomachine, and a heat recovery steam generator operatively coupled to the gas turbomachine and the steam turbomachine. The heat recovery steam generator includes a high pressure reheat section provided with at least one high pressure superheater and at least one reheater. The combined cycle power plant further includes a controller operatively connected to the gas turbomachine, the steam turbomachine and the heat recovery steam generator. The controller is selectively activated to initiate a flow of steam through the heat recovery steam generator following shutdown of the gas turbomachine to lower a temperature of at least one of the high pressure superheater and the at least one reheater and reduce development of condensate quench effects during HRSG purge of a combined cycle power plant shutdown.

摘要： Embodiments of the invention can provide systems and methods for pre-warming a heat recovery steam generator and associated steam lines. According to one embodiment, a method for pre-warming a heat recovery steam generator can be provided. The method can include providing heating steam from a steam source. The heating steam is directed from the steam source to a superheater so that at least a portion of the superheater can be warmed. Once exiting the superheater, the heating steam can be further directed from the superheater to at least one bypass line and maintained in the bypass line until the bypass line attains a predefined temperature or pressure. Furthermore, the method can include directing, after the bypass line attains a predefined temperature or pressure, at least a portion of the heating steam from the bypass line to a reheater so that the reheater can be warmed.
