Product Description

3 Pass CDZL Series Coal Wood Chip fired Hot Water Heater Boilers for bath center


New type DZL(H) hot water boiler is the single drum longitudinal type water and fire tube shell water boiler,the burning equipment is the moving grate.The furnace wall take heat resistance as the whole trumpet bell and ramming to be the new process,the boiler host outside is the solid figure guard board shell.

 

This hot water boiler adopt chain grate,suitable for molding pellet fuel,can add a small amount of wood,wood block,also can burn with coal.


Combustion Processe:

 

The fuel burning at the furnace through, the exhaust gas flow from the boiler barrel bottom to the smoke window outlet on the Eight character wall, then enter convection bank at the both wings, next enter the thread smoke tube through the front smoke box, pass by economizer, dust remover, and induced draft fan, finally discharged to the atmosphere by chimney.

 

Feeding System Introduction:

1.Conveyor feeding mode (For biomass particles)

2.Elevating automatic feeding (For coal)

3.Blast feeding (For size of less than 50mm of small sawdust, or rice husk)

4.Screw feeder
