    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.

    摘要: The disclosed embodiments relate to a system and method that allows air to be extracted from a plurality of gas turbine engines and fed to a downstream process, even in situations in which one or more of the gas turbine engines are operating in a part load condition. For example, in an embodiment, a method includes monitoring signals representative of a header pressure of a header, or a pressure of extraction air flow from one or more gas turbine engines to the header, or both, and maintaining substantially continuous flows of extraction air from the gas turbine engines to the header. The substantially continuous flows are maintained when the gas turbine engines are under symmetric and asymmetric load conditions.
