Regularly drain and expand the container

Regularly drain and expand the container

The boiler regularly discharges sewage or waste hot water whose pressure is higher than that output by the regular blowdown expander, and separates secondary steam and waste hot water through decompression and expansion. The secondary steam can be discharged into the atmosphere or used as a heat source, and the waste hot water is generally discharged into the sewer system through the sewage cooling pool. In this way, the recovery of secondary steam and waste hot water can be used as a heat source, and a part of the heat loss caused by the boiler blowdown can be recovered, and the efficiency of the boiler can be improved.
