【Abstract】 Determination method of optimal back-pressure for optimizing operation of double back-pressure condensers in large-scale power plants has been put forward, and computation model being given. Combined with data obtained from the optimization test of a 600MW steam turbine, optimal back-pressure of the double back-pressure condenser and the optimal operation mode of circulating water pumps are achieved from said computation. These results have been used in the field, obtaining better effectiveness.更多还原
