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 chain grate which can feed coal by stocker/ and is equipped with drums, 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 operation mechanization, supporting auxiliary engine is complete.

Product characteristic:

1.Smoke tubechange single return instead of two return,avoid tube sheep crack.

2.With thread smoke tube,increase the transfer heating efficiency.

3.Working steady .adjust easily ,steam presure is enough,thermal efficiency is high.

4.This boiler has dust remove function by itself.

5.Many kinds of coal is adaptable.

6.Manually operate easy

7.using thicken and more quality insulating material

8 using Chinse charater "eight "fule gas arrangement ,the smoke entry the front smoke box smoothy ,drop down the temperature of tube plate in high temperature area avoied explosive .
