Just how to resolve the slagging of biomass boilers?<br>
Biomass boilers adopts biomass wastes or biomass pellets as fuel. In grain pellet mill for sale burning of pellet gas, the volatiles turn into gas and also have actually complicated reaction with smoke as well as dirt, coagulate and comply with the heating pipeline surface area. The slagging as well as ash down payment will affect the procedure and safety of boilers. In this article, I will certainly examine the features of slagging, find out the reason of biomass boiler slagging, and also advanced efficient solutions.



Factors for biomass boiler slagging

The slagging of biomass boilers describes the ash created in the burning of biomass gas. At heat, the ash remains in fluid or soft strong condition. Once they touch the heating surface, they would stick to it and also develop right into slag.



Biomass fuel make-up and environmental tool

The ash melting point is impacted by the make-up of biomass fuel and ecological medium. If there are incompletely ignited fuels, they will make the ecological tool weakly reductive, as well as reduced the melting point. Under this problem, the ash are simple to attach to the hearth and the wall of superheater. If the biomass fuel has high wetness content, the heavy steam will soften potassium, which is the significant web content in ash.



Impurities in biomass gas create slagging

A huge part of biomass gas are made by more than 1 raw material. Sometimes they are mixed with dirt and also sand. animal pellet machine transformed the make-up as well as melting temperature of biomass gas. With high ash and also alkali steel content, these impure biomass fuels are much easier to cause slagging.



Inadequate air in boilers for burning

Occasionally the biomass gas are dispersed erratically in boilers. They become heat combustion mass and also shed with inadequate oxygen, which will certainly create slagging. Not enough ventilation quantity will boost the slagging level. Consequently, to avoid biomass boiler slagging, you ought to regulate the proportion of gas as well as air.



You can change the air proportion by getting rid of some gas. Besides, slagging might develop from boiler problems. The feeding device can trigger fuel stacking as well as aggravate slagging.



Uneven warm distribution of central heating boiler surface area

The boiler inside temperature level and also heat circulation have great effect on the slagging. As experience shows, slagging usually appears in flue as well as superheater surface area. When the liquid or soft solid ash approach the home heating surface area, it do not have adequate time to cool off, so it is simple to abide by the heating surface as well as gather. As looks into shown, the higher the boiler temperature, the even more slagging. Slagging impact the warmth exchange of boiler surface, block the flue, boost the smoke circulation rate, as well as aggravate the heating surface wear.



Just how to solve the slagging of biomass boilers?

Currently we know the slagging of biomass boilers emerges from the biomass fuel properties and boiler design. To minimize the slagging, we must select high quality biomass pellets and also high-efficiency central heating boilers, as well as manage the feeding speed. But you can not eliminate slagging completely. You require to clean the biomass boilers routinely.



Heavy steam residue blower

Generally, they use heavy steam residue blower to remove slagging in boilers, however the cleansing impact is barely sufficient. They need to wash the central heating boiler with high-pressure water.



The potassium in biomass fuel create silicon in burning and reduced the softening temperature level to 800 ℃, which is in the range of superheater. So the soften ash is easy to attach to the warm wall surface as well as hard to be gotten rid of by steam soot blower



Besides, vapor residue blowers has adhering to downsides. The central heating boilers cleaned by heavy steam soot blower have to wait for 15 days for following use. The removing area is limited, with some dead angles. As the soot blowing interval is long, there are way too much ash deposited in the heating surface area. They may sintered and set, as well as boost the cleaning problems.



defocusing inhibitor and also pulse gas ash blower.

Nowadays, several biomass central heating boilers adopt defocusing inhibitor as well as pulse gas ash blower to address biomass central heating boiler slagging as well as attained remarkable impact.




Defocusing inhibitor is a fuel additive with high melting point as well as combustion improver. When it is splashed right into the fireplace, it will mix with fly ash and also adhere to the half-melt ash. It will transform the melting point of ash as well as damage slagging. It can also form metal film on the pipeline surface area to stop acid dew point corrosion.



Pulse gas ash blower can remove the ash down payment on the boiler home heating surface area by purging, acoustic tiredness, thermal cleaning and also regional resonance. Finally, the gas flow eliminate the ash.



Select the best method to solve slagging trouble

To use premium quality biomass fuels in central heating boilers can decrease slagging, but the cost will certainly boost. If you have to use low quality biomass fuels, which has high moisture and also contaminations content, slagging is unavoidable. To make sure the stable running of central heating boilers, you can incorporate defocusing inhibitor as well as pulse gas ash blower to efficiently fix the slagging trouble.
