SZL series coal-fired hot water boiler

SZL series coal-fired hot water boiler
Product Detailed
1.coal-fired hot water boiler 2.Heating capacity:1.4-21t/h 3.Pressure:0.7-1.25MPa

SZL packaged water-tube steam 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.Coal econnomizer is mounted at the rear of bolier.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 with the chimney via coal economizer,dust collector and draught fan.

Compact soize,small installation spaxe,single-floor boiler room,cost-effective omfrastructure.Great assembily level,short installation period and cheap installation.

Sufficient and reasonable heating area,quick temperature/pressure-rise of boiler,satisfactory productivity and high heating efficiency.

Introduce the air with air distribution chambers of grate.All air distribution chambers can adjust the air flow indepedently and grate speed can be regualated in the stepless way.Wide range of applicable coals.Thorough combustion.

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