Abstract

Abstract

To provide reference experiences and optimization methods for steam cycle performance of F advanced class combined cycle, impacts of high pressure main steam pressure drop are investigated by GTpro software. The calculation results show that the loss of power output becomes smaller caused by pressure drop when steam turbine inlet steam pressure grows higher. By the analysis of main steam flow measuring methods, flow meter along main steam piping could be cancelled, which makes steam turbine higher efficiency and produces more profits. The research and analysis could provide a optimized design method of main steam system for other gas-steam combined cycle projects.
