Boiler Startup Drain Tank
The boiler startup drain tank is mainly applicable to the start-up system of supercritical or ultra supercritical unit. The high-temperature and high-pressure drain water is cooled, expanded and separated to obtain steam and water. The steam is directly discharged into the atmosphere or into the LP feedwater heater as a heat source to recover heat and improve the thermal efficiency of the unit. The water is collected in the drain tank.
