Experimental research on economical efficiency of sliding pressure operation of K-215-130-1 type steam turbine

Abstract

Abstract: Taking the Sovietmade K-215-130-1 condensing turbine as example, the thermodynamic performances of steam turbine under fixed valve position in constant pressure operation mode and in sliding pressure operation mode were tested and compared; and the optimal operation modes under different conditions were determined. The test results shows that, under the load range of 135MW to 175MW, the economical efficiency of sliding pressure operation mode is better than that of constant pressure operation mode. The result can be used to direct unit economical operation effectively and reduce the net coal consumption rate of the unit greatly.

Key words: steam turbine, constant pressure operation, sliding pressure operation, economical efficiency
