70MW DHL series coal-fired hot water boiler for a heating power company

ZOZEN DHL series coal-fired watertube hot water boilers are ideal equipment for central heating. This series of boilers are forced-circulation, single-drum horizontal chain grate hot water boilers. Membrane water walls are arranged around and in the middle of the furnace to absorb the radiant heat of high-temperature flue gas in the furnace. And the large furnace extends the residence time of the flue gas in the furnace, making the fly ash and combustible gas be fully burned, which not only improves the thermal efficiency, but also greatly reduces the amount of fly ash and the original emission concentration of the boiler. The boiler arch adopts the scientific and technological achievements of the Xi'an Jiaotong University's to ensure the combustion effect of inferior coal and expand the coal adaptability. Boiler grate adopts bar grate to improve the operation safety. Through stepless speed regulation, users can adjust the load arbitrarily without affecting the thermal stability of combustion.

Heating companies in Liaoning have already provided heating guarantees to cope with severe cold weather. Among them, Fushun Shunnan Heating Power Co., Ltd. chose to cooperate with ZOZEN. Before the heating season of 2017, ZOZEN completed the commissioning of the DHL series coal-fired watertube hot water boiler for Shunnan Heating Power, and its excellent performance won the favor and praise of Shunnan Heating Power.
