Yongxing SZL Coal Biomass boiler adopts a double boiler barrel and vertical arrangement; the combustion mode is chain grate, fuel is coal or biomass.
Biomass energy has various advantages because of its vital reproducibility.
In the combustion process, we guarantee that the boiler you buy will not produce waste gas, waste, waste smoke, and low cost, easy to obtain, and will realize waste reuse, in line with the needs of the world’s environmental development.
The upper part of the SZL consists of the body pot, the descending tube, and the lower part of the chain grate.
When coal or biomass is burned in the chain grate combustion chamber, the flue gas will enter the tail flue through the boiler front furnace, #2 burnout chamber, convection tube bundle. Then it is discharged into the atmosphere through a multi-pipe dust remover, a water film dust remover, an induced draft fan, a chimney, etc.
SZL type biomass boiler adopts a membrane water-cooling wall structure on both sides of the furnace, which improves the boiler’s sealing and increases the volume and heating surface of the stove.
The best thing is that the front and rear walls are equipped with secondary air, which not only makes the fuel burn up thoroughly, improves the combustion efficiency and thermal efficiency, and reduces the input of fuel cost, but also reduces the generation of waste and waste residue.
What’s better is that our boiler has the advantages of a high automation level, safe and stable operation, a perfect protection function, and so on. It is the best choice for you to buy our boiler.
SZL Boiler Double Drum Coal Biomass Fired Steam Boiler System
1. For your configuration of high heat exchange efficiency of the convection tube bundles so that your SZL Boiler running efficiency is stable.
2. Let you enjoy the neat and beautiful chain grate panel, and the front and rear smoke box panels are all cut with a CNC plasma cutting machine.
3. You can see the pan’s large volume and the complete internal device.
4. You can get a full set of boiler protection functions, automatic feed water regulation, automatic alarm of high and low water level, automatic protection of overpressure, automatic protection of flameout, etc.
5. To ensure your operation’s safety, the SZL boiler is running smoothly and has a specific capacity for overload operation.
6. Match reasonable front and rear furnace arches; the furnace arch coverage rate is large, and the furnace temperature is high.
7. Main features: SZL Boiler double drum layout, high combustion efficiency, saving you 5-10% operating costs.
8. Reasonable design so that your boiler heating surface of the falling body and the cross-section of the rising pipe are in exemplary configurations, and the boiler running condition is stable.
9. You can adjust the amount of air required by different fuels in different combustion stages of each air chamber artificially. The horizontal wind pressure is consistent, and partial burning will not occur.
