Problems solved by technology

Furthermore, large temperature differences between the working fluid in the HRSG and the hot turbine exhaust gases, especially during the initial start-up phase, can cause thermal stress on various components of the HRSG, which can affect overall HRSG performance

Embodiment Construction

[0093] Reference will now be made in detail to embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. The detailed description uses numerical and letter designations to refer to features in the drawings. Like or similar numerals are used in the drawings and description to denote the same or like parts of the present invention. As used herein, the terms "first," "second," and "third" are used interchangeably to distinguish one element from another, and are not intended to indicate the position or importance of individual elements. The terms "upstream" and "downstream" refer to relative directions with respect to fluid flow in a fluid pathway. For example, "upstream" refers to the direction from which fluid flows, and "downstream" refers to the direction to which fluid flows.

[0094] Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled...

Abstract

A combined cycle power plant comprises a compressor, a combustion section including a compressor discharge casing which is disposed downstream from the compressor, a turbine disposed downstream from the combustion section and an exhaust duct disposed downstream from the turbine section. The compressor, the compressor discharge casing, the turbine and the exhaust duct define a primary flow passage through the gas turbine. A heat recovery steam generator is in thermal communication with the exhaust duct and in fluid communication with a steam turbine. A blower is in fluid communication with the primary flow passage upstream from the heat recovery steam generator such that the blower draws compressed air from the primary flow passage during turning gear operation of the gas turbine.

Description

technical field [0001] This application is based upon and enjoys the benefit of priority from U.S. Provisional Patent Application Serial No. 62 / 042814 filed August 28, 2014, the disclosure of which is hereby incorporated by reference in its entirety for all purposes middle. [0002] The present invention relates generally to combined cycle power plants. More specifically, the present invention relates to systems and methods for conserving thermal energy within a heat recovery steam generator portion of a combined cycle power plant during turning gear and / or non-combustion operation of a gas turbine. Background technique [0003] One type of combined cycle gas turbine power plant utilizes at least one gas turbine and at least one steam turbine in conjunction to generate electricity. The power plant is arranged such that the gas turbine is thermally connected to the steam turbine through a heat recovery system, such as a heat recovery steam generator "HRSG". A gas turbine g...
