Exactly how to address the slagging of biomass boilers?<br>
Biomass boilers takes on biomass wastes or biomass pellets as gas. In the burning of pellet gas, the volatiles develop into gas as well as have complicated response with smoke as well as dust, coagulate and also abide by the home heating pipe surface. The slagging as well as ash deposit will certainly impact the procedure and security of central heating boilers. In this article, I will analyze the functions of slagging, discover the reason of biomass central heating boiler slagging, and also advanced efficient solutions.



Factors for biomass central heating boiler slagging

The slagging of biomass boilers refers to the ash created in the burning of biomass fuel. At heat, the ash is in liquid or soft strong standing. Once they touch the heating surface area, they would certainly comply with it and also create into slag.



Biomass fuel composition and also environmental tool

The ash melting point is impacted by the structure of biomass fuel and also ecological tool. If there are incompletely combusted gas, they will make the environmental medium weakly reductive, as well as lower the melting point. Under this condition, the ash are easy to affix to the hearth and the wall of superheater. If richi machinery has high wetness material, the steam will soften potassium, which is the significant material in ash.



Pollutants in biomass gas create slagging

A big part of biomass gas are made by greater than 1 resources. In some cases they are combined with dirt as well as sand. These pollutants transformed the structure as well as melting temperature of biomass fuels. With high ash and also alkali metal material, these unclean biomass fuels are simpler to cause slagging.



Not enough air in boilers for burning

Often the biomass fuels are distributed erratically in boilers. They end up being high temperature combustion mass and melt with insufficient oxygen, which will certainly cause slagging. Not enough ventilation amount will certainly boost the slagging level. As a result, to avoid biomass boiler slagging, you ought to control the proportion of gas and air.



You can change the air proportion by removing some gas. Besides, slagging might arise from central heating boiler issues. The feeding tool can trigger gas piling and also intensify slagging.



Unequal warmth distribution of central heating boiler surface area

The boiler inside temperature and warm circulation have terrific influence on the slagging. As experience shows, slagging generally appears in flue as well as superheater surface. When the fluid or soft solid ash approach the heating surface area, it don't have sufficient time to cool down, so it is simple to stick to the heating surface area and also accumulate. As researches confirmed, the higher the boiler temperature level, the more slagging. Slagging affect the heat exchange of boiler surface area, obstruct the flue, raise the smoke circulation rate, and exacerbate the home heating surface area wear.



Just how to solve the slagging of biomass boilers?

Currently we know the slagging of biomass central heating boilers arises from the biomass gas residential properties and boiler layout. To reduce the slagging, we should pick excellent quality biomass pellets and also high-efficiency boilers, and also regulate the feeding speed. But richi machinery can not remove slagging entirely. You require to cleanse the biomass boilers consistently.



Steam soot blower

Generally, they make use of heavy steam residue blower to eliminate slagging in central heating boilers, but the cleaning impact is hardly adequate. They have to clean the central heating boiler with high-pressure water.



The potassium in biomass gas create silicon in burning as well as reduced the softening temperature level to 800 ℃, which remains in the series of superheater. So the soften ash is easy to connect to the warm wall and also tough to be eliminated by heavy steam soot blower



Besides, vapor residue blowers has complying with drawbacks. The central heating boilers cleansed by heavy steam soot blower need to wait on 15 days for next usage. The removing location is restricted, with some dead angles. As the soot blowing interval is long, there are way too much ash transferred in the home heating surface. They might sintered and set, and also enhance the cleansing problems.



defocusing prevention and also pulse gas ash blower.

Nowadays, several biomass boilers embrace defocusing prevention as well as pulse gas ash blower to address biomass boiler slagging as well as attained impressive impact.



Defocusing prevention is a fuel additive with high melting point and burning improver. When it is sprayed into the fireplace, it will mix with fly ash and stick to the half-melt ash. It will certainly transform the melting point of ash and also ruin slagging. It can additionally form metal movie on the pipeline surface area to prevent acid dew point rust.



Pulse gas ash blower can remove the ash deposit on the central heating boiler heating surface area by removing, acoustic tiredness, thermal cleaning and local vibration. At last, the gas circulation remove the ash.




Pick the best means to solve slagging trouble

To use premium quality biomass gas in central heating boilers can reduce slagging, however the expense will increase. If you have to use low quality biomass fuels, which has high dampness as well as impurities material, slagging is inevitable. To make sure the steady running of central heating boilers, you can combine defocusing prevention as well as pulse gas ash blower to efficiently fix the slagging problem.
