Development of a non-standard reheat parameter co-firing process waste gas coal powder boiler
Based on the cogeneration project in a certain chemical park,a 150 MW backpressure steam turbine generator unit is equipped.In order to treat the process waste gas produced in the production process of the chemical park,our company has inde-pendently developed and designed a non-standard reheat parameter mixed combustion waste gas coal powder boiler.The boiler has ultra-high temperature and subcritical parameters,with a maximum continuous evaporation capacity of 450 t/h,a pressure and temperature parameter of 17.5 MPa/571℃ for the superheater,and a steam flowrate of 439.3 t/h for the reheater.The pressure and temperature parameters of the reheater are 10.02 MPa/530℃,and the fuel is coal powder co-firing process exhaust gas.Af-ter the boiler is put into operation,it can safely and effectively co-firing process exhaust gas and all indicators operate normally,meeting user needs.
