DZL type chain grate coal fired steam boiler is a kind of horizontal three-return water and fire pipe mixed steam boiler, which is arranged with a bunch of threaded smoke pipe inside the boiler barrel.The left and right sides of the furnace chamber are equipped with water cooling walls of light pipes.It adopts light chain grate to realize mechanical coal feeding, equipped with blower and induced draft fan for mechanical ventilation, and equipped with scraper type slag discharge machine to realize automatic slag discharge.The front and rear arch of the steam boiler adopts new energy saving technology.After the fuel falls on the grate from the coal sill and enters the furnace for combustion, the flame, through the refraction of the rear arch, turns upward through the burning Chambers on both sides of the body and turns to the front smoke box, and then turns back to the tube bundle in the pot by the front smoke box, enters the economizer through the rear smoke box, and then is pumped by the induced draft fan to the air through the flue to the chimney.
