coal boiler

DZL Biomass Fired Boiler advantages

1. Reliable Operation:
The heating surface of boiler is reasonably settled, the water circulation fluent, to ensure that each heating furnace cool down timely, and ensure the boiler running safety.

2. Easy Maintenance:
The top of boiler barrel set manhole, serviceman can enter to inspect and maintain. The front smoke box easy to open, serviceman can easy and clear inspect, provide excellent conditions for correctly handle.

3. Full Combustion:
In the cooperation of blower, and reasonable design of furnace structure, the fuel can be fully burning, can remove the black smoke effectively.

4. High Efficiency Grate:
Boiler grate use matching coal fuels grate, avoid the problem of air leakage, fuel leakage and uneven ventilation, and easy operation, have lots of advantages compared to traditional grate.

5. Easy to Remove Ash:
Set several remove ash hole on boiler, can remove ash timely and efficiently, to avoid ash deposition in boiler making the boiler running is affected or thermal efficiency is dropped etc. To ensure stability of boiler loading.

6. High Security:
Feed water system adopt computer controlling, automatic feed water. Equip with water lack protection and over pressure protection devices, security and reliable.

7. Long Life and Durable:
Excellent professional design, advanced production processes, strict quality inspection control, is the quality assurance of each boiler, the service life of normal use boiler all above 20 years.

8. Environmental Protection and Low Noise:
The boiler smoke is low emission, and equip with high efficiency dust remove device at boiler end, low noise fans, to make the smoke emission reach to nation environmental protection requirements.

DZL series steam boiler is the kind of automatic, horizontal, three-pass, and fire tube boiler;
Featureas of DZL boiler:
1. Adopting the new-type structure
The new-type structure steam boiler adopts single drum vertical type arrangement, and two sides of the furnace are arranged with water cooled wall. The upper part is welded with the boiler drum, and the lower part is welded with the right and left container. The back arch and the drum space are arranged with convection bank, whose upper part is welded with boiler drum, and whose lower part is connected with all containers. It is the compact structure.
2. Organizing the fire in the furnace reasonably. The furnace adopts double layers anti-burning structure which is formed by the pre-combustion chamber and combustion chamber. As for the boiler design, dividing the furnace into the pre-combustion chamber and combustion chamber, which is good for strengthening the fuel burning, and decreasing flying ash fuel and flying ash content.
3. Among the convection tubes, there are many smoke baffle walls, which can make fire turning-back many times and are good for removing the dust of the furnace. Boiler itself has a dust removal function, so that dust emissions from the boiler to reach the target state environmental regulations. This series of boiler adopts arched tube plate, two-wing flue pipe etc, thread, solve the smoke pot shell boiler tube plate cracking, the bulge, tube boiler water-cooled wall tube, thermal efficiency is low, the coal output, adaptability, etc.
