A power plant is equipped with a 350MW pure condensate steam extraction unit and a 50MW back pressure unit.Due to the market factors of users,the heat load of the back pressure unit is sometimes insufficient,which leads to the unstable operation of the boiler and threatens the operation of the unit and the heating safety of the users.By coupling the steam used by the small turbine of the pure condensate extraction unit,a stable large heat user is added and the thermal efficiency of the back pressure unit and the pure condensate extraction unit are improved.Indirectly,the deep energy saving effect of the double unit operation is achieved,and a new idea is provided for the energy saving technology transformation of similar configuration heating units.
