Introduction of DZL series coal-fired steam boiler
The DZL series quick-installed boiler is a horizontal three-pass water-fire tube chain grate boiler designed for bituminous coal combustion. The boiler features a single drum layout with threaded smoke tubes for convective heating surface, and water-cooled walls on both sides of the drum for radiant heating surface. The combustion equipment adopts a lightweight chain grate, and the boiler is delivered in a complete quick-installed form. The electrical control system enables infinitely variable control of the grate, with alarm and interlock protection for critical parameters.
Feature of DZL series coal-fired steam boiler
1. Arched tube sheets and threaded fire tube was first adopted in China to increase heat transfer and completely solve the problem of cracking of the back tube sheet.
2. The welding of smoke tube and the tube plate adopts pre-expansion to eliminate the gap between the tube and tube plate, then be welded by automatic argon arc welding, which effectively eliminate stress and prolong boiler life.
3.Threaded smoke tubes are highly efficient heat transfer elements which is from many years research of our company. After continuous optimization, the heat transfer coefficient is 1.8 times higher than normal smoke tubes.
4.The high-temperature smoke generated by the combustion first enters the horoscope flue on both sides of the body from the tail (in this case, the boiler is water tube type), and the flue gas flows outside the tube.
