DZL type horizontal chain coal - fired steam boiler is a horizontal three - trip water - fire tube boiler.Two fire tubes are arranged in the pot barrel, and both sides of the furnace chamber are equipped with light tubes and water wall tubes.The combustion equipment adopts light chain grate to realize mechanical coal feeding, and is equipped with drum and induced draft fan to realize mechanical ventilation.The fuel falls on the grate from the coal sill, burns along with the grate, and the flue gas passes through the upper combustion chamber of the rear arch, enters the first bundle through the smoke chamber of the rear shed pipe to the front smoke box, folds into the second bundle from the front smoke box to the back smoke box, is introduced into the flue, dust collector and chimney through the induced draft fan, and finally exhausts to the atmosphere.The boiler automation level is high, the boiler feed water automatic regulation, high and low water level alarm, low water level interlock protection, lead, fan interlock protection.Boiler coal, slag and other operation mechanization, reduce the labor intensity of workers, complete supporting auxiliary machines.
DZL Automatic Coal Fired Steam Boiler features:
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
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.
