Industrial Production complete system fuel fuel horizontal coal fired hot water boiler 's working principle

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.

Industrial Production complete system fuel horizontal coal fired hot water boiler 's feature

1.Smoke tube change single return instead of two return,avoid tube sheep crack coal boiler

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

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

4.This coal boiler has dust remove function by itself.It's automatic coal fired steam boiler

5.Many kinds of coal is adaptable.

6.automatically control pressure:water level control :safety automatically chain control(boiler super pressure pretection,boiler water lever overloading protection,feed water pump ,induced draft fan ,air blower,slag machine ,reduction gears ,coal conveyor as so on when failure occurred ,automatic alarm start .

SZL coal fired hot water boiler:

SZL horizontal double drums coal fired hot water boiler is the double-cylinder, water-tube assembly, chain grate boiler. Two cylinders are laid at the upper and lower level of boiler longitudinally along the center. Front section of the upper cylinder and water-cooled tubes at side walls form the radiation-heating area in the hearth. While the rear section and tube bank in the lower cylinder serve as convection-heating area, the coal economizer is mounted at the rear of boiler. Some heat of hot combustion fume is absorbed by the hearth, then hot combustion heat flows to the convection heating area through cooling chamber and exhausts outside through the chimney via coal economizer, dust collector and draught fan.

Advantages and features of SZL horizontal double drums coal fired hot water boiler:

1. Compact structure, small installation space, single-floor boiler room, cost-effective investment in infrastructure. Great assembly level, short installation period and cheap installation.

2. Heating surface distribution is sufficient and sensible, the boiler heating-up and pressure boost -up quickly, strong output, high thermal efficiency.

3.Introduce the air with air distribution chambers of grate. All air distribution chambers can adjust the air flow independently and grate speed can be regulated in the stepless way. It could be used by wide range of applicable coals and could burn thoroughly.

4.Electrical cabinet is equipped with complete automatic control and monitor instruments with high automation, safety, reliability and easy operation.
