DZG serie biomass fired steam boiler



 Sort:  DZG serie biomass fired steam boiler Symbol:  DZG0.5-6-0.7/1.25/0.8-M
 Size:  
Price:  0  
Detail:

 

DZG serie biomass fired steam boiler is a horizontal package single drum vertical type water fire tube boiler shell fixed grate biomass fired steam boiler, top-bottom side combination type package structure, the top was made up of boiler proper, drum, boiler setting and insulation layers etc, the bottom was made up of grate installation. The boiler adopted horizontal type three pass water fire tube mixed structure, the drum was weld by tubesheet, cylindrical shell and pipe, it has a down comer of each sides of boiler, the down comer send the boiler water to side headers and water tube wall as a water circulation circuit, the boiler heating surface are at the right-left side of furnace collocate the waterwalls radiant heating surface and inter drum smoke tube convection heating surface.

 

The worker put the fuel from front or both sides boiler door to the high temperature area of furnace, through preheat dry distillation, combustion and burnaway become to slag drop into the slag pool which under the grate, finally, the worker clean out the boiler.

The flue gas become to eddy between the front - back arch, and mixed fully with air, heating front arch to improve the firing condition at the same time. Through the exit smokestack which at the top of arch and enter into the first convection smoke tube, passing the front smoke box enter into the secondary convection smoke tube, then through the economizer, dust collector of back smoker box, finally, will be discharged out off chimney by induced draft fan.

 

 

Fuel: fire biomass pellet, wood, sawdust, stalk, rice dull, bagasse etc biomass fuels.  

 

Features:

 

1. Lower operation cost, have the steam pressure and water leave protect equitment for ensuring operation safe and reliable.  

2. Higher thermal efficiency;

3. Hand-fired grate: feed fuel and clean slag by worker.

3. It is a package boiler, just installation the parts are valve gauge, tube, forced draft fan, induced draft fan, flue, dust collector and water electric system at the field , then can start to work. also has the feature of firing quickly, burning safely.

4. It is easy to transportation and install, lower capital investment.
