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.


Technical characteristics



One of the earlist manufacturers of fast-assemly thread pip chain grate boiler in China, In the past 10 years, the products have been replaced many times, more mature, similar products have produced more than 6000 units

2.Advance technolody

Adopt many advanced technology: threaded pipe, airfoil flue , Convex tube plate, the backwater towards high temperature tube plate, simple loop circuit, dust separated chamber, big furnace, compact structure so on.

3. Stable operation

The steam boiler has stable operation, low failure rate and never have safty accident.

Boiler can work 20 years.


The only boiler factory have 20 0000fatigue test to boiler in China


High efficiency, energy saving, good economy.

6. High level Aumotic control system

The boiler automaticon lelvel is high, the boiler feedwater automatic regulation, high-low water level alarm, low water level interlock protection, fan interlock protection, automatic feeding fuel, automatic water feeding, automatic ash remove function.
