COMBINED CYCLE POWER PLANT HAVING REDUCED PARASITIC PUMPING LOSSES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17972606 titled 'COMBINED CYCLE POWER PLANT HAVING REDUCED PARASITIC PUMPING LOSSES
The abstract describes a combined cycle power plant (CCPP) that includes a gas turbine with compressor, combustion, and turbine sections, as well as a heat recovery steam generator (HRSG) with a first economizer. The HRSG receives exhaust gas from the turbine section and includes a fuel heating system with a high temperature heat exchanger connected to the fuel supply line and the first economizer. A feedwater pump is also included in the CCPP.
- Gas turbine with compressor, combustion, and turbine sections

Original Abstract Submitted
A combined cycle power plant (CCPP) is provided. The CCPP includes a gas turbine that has a compressor section, a combustion section, and a turbine section. The CCPP further includes a heat recovery steam generator (HRSG) that has a first economizer. The HRSG receives a flow of exhaust gas from the turbine section. The HRSG further includes a fuel heating system that has a fuel supply line and a high temperature heat exchanger disposed in thermal communication on the fuel supply line. The fuel supply line is fluidly coupled to the combustion section. The high temperature heat exchanger is fluidly coupled to the first economizer such that the high temperature heat exchanger receives water from the first economizer. The CCPP further includes a feedwater pump that is fluidly coupled to the high temperature heat exchanger.
