The bad performance problem of cold end system concerning home-made imported type 300 MW steam turbine units has universality

seriously affecting economic operation of the thermal power equipments

but it is difficult to reach a common understanding for lack of test data. A lot of thermal power plants are trying to improve the unit’s cold end performance by increasing cooling surface of its condenser

it is considered after calculation analysis and verification of field test data that the designed cooling surface of home-made 300 MW steam turbine units is suitable to keep in a range of (16 000～17 000)m~2.
