摘要
Abstract
During its operation process,the combined cycle unit will deviate from designed conditions,such as rise of exhaust gas temperature,change of exhaust gas flow,and so on,but the steam turbine will still keep its original sliding pressure curve mode,so it will deviate from optimal parameters in actual operation. This paper uses MATLAB to establish a simula-tion calculation model for heat recovery boiler-steam turbine for optimizing sliding pressure parameters and compares chan-ges of optimal sliding pressure curves under different exhaust gas conditions of the gas-steam turbine. Results indicate that when efficiency of the gas-steam turbine decreases and the unit runs with the mode of controlling exhaust gas temperature of the turbine,the optimal sliding pressure curve of the boiler will move up. Meanwhile,decline of efficiency of the turbine will cause rise of exhaust gas flow and increase of output of the turbine,which will reduce influence of efficiency decline of the turbine on decrease of output of the combined cycle unit.关键词
