Abstract:For meeting the needs of steam system optimization and the requirements of unit quick start-up in large scale natural gas-fired combined cycle power plant, it is critically important to choose the steam turbine with appropriate structure. This paper expounds the features of steam turbine in combined cycle and make analysis and comparisons of steam turbine cylinder and exhaust models in combined cycle. Also the most appropriate steam turbines that meet tri-pressure and reheat steam system are recommended in this paper.
Keywords:natural gas  large combined cycle power plant  steam turbine
