Abstract
The present application provides a power generation system. The power generation system may include a gas turbine engine, a steam turbine, and a steam turbine preheating system. The steam turbine preheating system may include a steam generator that creates a flow of steam to preheat the steam turbine from an extraction of the gas turbine engine.
Claims20
A power generation system, comprising:
- a gas turbine engine;
- a steam turbine;
- and
- a steam turbine preheating system;
- wherein the steam turbine preheating system comprises a steam generator that creates a flow of steam to preheat the steam turbine from an extraction of the gas turbine engine.
2 more elements
A method of preheating a steam turbine in a power generation system, comprising:
- extracting hot combustion gases from a gas turbine to a steam generator;
- flowing feedwater to the steam generator;
- exchanging heat between the hot combustion gases and the flow of feedwater to create a flow of steam in the steam generator;
- and
- flowing the steam to the steam turbine to warm a shell of the steam turbine.
2 more elements
A combined cycle power generation system, comprising:
- a gas turbine engine;
- a steam turbine;
- a heat recovery steam generator;
- and
- a steam turbine preheating system;
- wherein the steam turbine preheating system comprises a steam generator that creates a flow of steam to preheat the steam turbine from an extraction of the gas turbine engine and a flow of feedwater.
