It is respectively level-one attemperator and two level attemperators that the attemperator, which is two, wherein level-one attemperator and superheater and
High-pressure heater connects, and receives the superheated steam from superheater and the desuperheating water from high-pressure heater；Two level attemperator with
Level-one attemperator, high-pressure heater and steam turbine connection receive the desuperheated system from level-one attemperator and come from high pressure
The desuperheating water of heater, and to steam turbine feeding secondary desuperheated system.
Further include that a water feeding tank is connect with feed pump, water source is provided for feed pump.
It is additionally provided with oxygen-eliminating device in the water feeding tank.
Further include a low-pressure heater, low-pressure heater is connect with feed pump and high-pressure heater, and feed pump provides
Hot water to be added after low-pressure heater is heated enter high-pressure heater in.
