Coal Steam Boiler ,Coal fired steam boiler, travelling grate coal fired steam boiler China boiler Manufacturer , Thermax Boiler .

DZL type boiler is a horizontal three return fire and water tube type boiler. There are two fire tubes in the boiler barrel , with both sides light pipe water-wall tubes; the combustion equipment is chain grate , induced draft fan realize mechanical ventilation. Fuel from coal scuttle fell to grate stoker, along with the chamber into after burning, smoke after the upper chamber after arch, the smoke pass through behind of combustor, through up the combustor into the first tube bundle then get front smoke box ,then through the front smoke box into the second tube bundle then get to back smoke box , finally through the induced draft fan smoke the introduction into the flue, dust catcher and the chimney, the last row to the atmosphere. The boiler automation level is high, boiler water supply the automatic adjustment, high and low level alarm, low water level interlock protection, lead, blowers interlocking protection. Coal boiler, slag discharge supporting auxiliary engine is complete.

coal fired steam boiler design structure:

1.All designed with horizontal, smoke tube type.
2.Designed with one drum.
3.Burnt by chain grate, could burning more efficiently, and efficiency up to 78%.

Coal fired steam boiler systems and components:

1.Economizer / air preheater
2.Water treatment
3.Coal feeding system
4.Force draft fan / induce fan / air system
5.Dust remover
6.Electric controller
