Just how to solve the slagging of biomass boilers?<br>
fish feed pelleting machine price embraces biomass wastes or biomass pellets as gas. In the burning of pellet fuels, the volatiles develop into gas and have actually complicated reaction with smoke as well as dirt, coagulate and comply with the heating pipe surface. The slagging and ash deposit will certainly impact the operation and security of boilers. In this short article, I will evaluate the functions of slagging, learn the reason of biomass central heating boiler slagging, as well as put forward effective services.



Factors for biomass boiler slagging

The slagging of biomass boilers describes the ash generated in the burning of biomass fuel. At heat, the ash is in fluid or soft strong condition. Once they touch the home heating surface area, they would stick to it and also form into slag.



Biomass gas composition and ecological tool

The ash melting point is impacted by the structure of biomass fuel as well as ecological medium. If there are incompletely combusted fuels, they will make the environmental medium weakly reductive, and also reduced the melting point. Under this condition, the ash are simple to attach to the fireplace as well as the wall surface of superheater. If the biomass gas has high dampness content, the vapor will soften potassium, which is the significant content in ash.



Impurities in biomass gas trigger slagging

A big part of biomass gas are made by greater than 1 basic material. Sometimes they are combined with dirt as well as sand. mini fish feed making machine altered the make-up and also melting temperature level of biomass fuels. With high ash as well as alkali steel content, these unclean biomass fuels are less complicated to cause slagging.



Inadequate air in boilers for burning

Occasionally the biomass gas are dispersed unevenly in boilers. They end up being high temperature burning mass as well as shed with inadequate oxygen, which will certainly cause slagging. Inadequate air flow quantity will certainly boost the slagging level. As a result, to prevent biomass boiler slagging, you ought to control the proportion of gas and also air.



You can change the air percentage by getting rid of some gas. Besides, slagging may arise from small wood pellet machine . The feeding tool can create gas stacking and also exacerbate slagging.



Unequal warm circulation of central heating boiler surface area

The boiler inside temperature level and also warmth distribution have excellent impact on the slagging. As experience shows, slagging typically appears in flue and also superheater surface. When the liquid or soft solid ash approach the heating surface, it do not have adequate time to cool down, so it is simple to follow the home heating surface and also accumulate. As looks into verified, the greater the boiler temperature, the more slagging. Slagging impact the warm exchange of central heating boiler surface, block the flue, increase the smoke circulation speed, and also aggravate the heating surface area wear.



Exactly how to fix the slagging of biomass central heating boilers?

Currently we know the slagging of biomass boilers occurs from the biomass gas homes and also boiler design. To reduce the slagging, we must choose premium quality biomass pellets and high-efficiency boilers, and also control the feeding speed. Yet you can't get rid of slagging completely. You require to clean the biomass boilers frequently.



Vapor soot blower

Generally, they utilize steam residue blower to get rid of slagging in boilers, but the cleansing effect is barely satisfying. They need to wash the central heating boiler with high-pressure water.



The potassium in biomass fuel create silicon in burning and also lower the softening temperature level to 800 ℃, which is in the range of superheater. So the soften ash is very easy to attach to the warm wall and also tough to be removed by heavy steam soot blower



Besides, vapor residue blowers has adhering to downsides. The boilers cleansed by vapor residue blower need to wait for 15 days for following use. The purging location is restricted, with some dead angles. As the soot blowing interval is long, there are excessive ash deposited in the home heating surface area. They might sintered as well as solidify, and increase the cleansing problems.




defocusing inhibitor and also pulse gas ash blower.

Nowadays, many biomass central heating boilers take on defocusing prevention and also pulse gas ash blower to fix biomass boiler slagging and also accomplished amazing effect.



Defocusing inhibitor is a gas additive with high melting point as well as combustion improver. When it is splashed into the fireplace, it will mix with fly ash and also stay with the half-melt ash. It will alter the melting point of ash and also damage slagging. It can likewise create steel movie on the pipeline surface area to avoid acid humidity corrosion.



Pulse gas ash blower can clear the ash deposit on the central heating boiler home heating surface area by removing, acoustic exhaustion, thermal cleaning and also regional resonance. Finally, the gas circulation remove the ash.



Pick the very best way to solve slagging problem

To make use of high quality biomass gas in boilers can lower slagging, but the price will certainly raise. If you need to make use of low quality biomass fuels, which has high dampness as well as pollutants material, slagging is unpreventable. To make certain the secure running of boilers, you can integrate defocusing inhibitor as well as pulse gas ash blower to successfully solve the slagging trouble.
