Evaporator unit combined-cycle unit utilization type

摘要

The evaporator units are used in power engineering for combined cycle power plants for the production of additional water in the boiler and turbine combined cycle power plant cycle.; The technical result obtained by using the proposed utility model is to reduce the loss of thermal efficiency associated with water treatment, up to their complete exclusion by utilizing the heat of flue gas.; The solution of this technical problem is achieved by the fact that known evaporative installation combined cycle unit utilization type with the recovery boiler comprising an evaporator, piping feedwater, distillate and a first pump, according to the utility model is provided with a spreader having an input through the first pump and the three-way and regulating valves connected to the output of the gas preheater condensate recovery boiler, a pair of expander outlet is connected to the evaporator, and the output of a condensate - with a suction nozzle the second pump, the discharge nozzle is connected to the inlet gas preheater condensate.; 1 Fig.
