How to fix the slagging of biomass central heating boilers?<br>
Biomass central heating boilers adopts biomass wastes or biomass pellets as gas. In the burning of pellet fuels, the volatiles turn into gas as well as have actually made complex reaction with smoke and also dust, coagulate as well as abide by the home heating pipeline surface area. The slagging and ash deposit will affect the operation as well as security of boilers. In poultry mash feed machine , I will certainly evaluate the features of slagging, figure out the reason of biomass boiler slagging, and put forward efficient solutions.



Factors for biomass boiler slagging

The slagging of biomass boilers describes the ash produced in the burning of biomass gas. At high temperature, the ash is in liquid or soft strong standing. Once they touch the heating surface area, they would follow it as well as develop into slag.



Biomass fuel make-up and also environmental tool

The ash melting point is impacted by the structure of biomass fuel and environmental tool. If there are incompletely ignited gas, they will certainly make the environmental tool weakly reductive, and lower the melting point. Under this condition, the ash are very easy to connect to the fireplace and the wall of superheater. If the biomass gas has high wetness material, the vapor will soften potassium, which is the major content in ash.



Impurities in biomass fuels create slagging

A large part of biomass gas are made by greater than 1 resources. Occasionally they are blended with dirt and also sand. cattle feed pellet machine altered the make-up as well as melting temperature of biomass fuels. With high ash as well as alkali metal material, these unclean biomass gas are less complicated to create slagging.



Insufficient air in boilers for burning


In some cases the biomass fuels are distributed unevenly in boilers. They come to be high temperature combustion mass and also burn with inadequate oxygen, which will cause slagging. Not enough air flow amount will boost the slagging degree. For that reason, to avoid biomass central heating boiler slagging, you need to regulate the percentage of gas and also air.



You can change the air proportion by getting rid of some fuels. Besides, slagging might occur from boiler problems. The feeding device can cause gas piling as well as aggravate slagging.



Irregular warm circulation of central heating boiler surface area

The central heating boiler inside temperature and heat distribution have excellent impact on the slagging. As experience shows, slagging typically shows up in flue and also superheater surface. When the liquid or soft strong ash move toward the heating surface area, it do not have enough time to cool off, so it is very easy to stick to the heating surface and build up. As looks into shown, the higher the central heating boiler temperature, the even more slagging. Slagging affect the warmth exchange of central heating boiler surface, block the flue, boost the smoke flow speed, and worsen the heating surface area wear.



Just how to fix the slagging of biomass boilers?

Currently we know the slagging of biomass central heating boilers develops from the biomass gas residential or commercial properties and also central heating boiler style. To lower die for pellet mill slagging, we ought to pick top quality biomass pellets and high-efficiency boilers, and also regulate the feeding rate. But you can't eradicate slagging entirely. You need to cleanse the biomass boilers on a regular basis.



Steam soot blower

Generally, they make use of vapor soot blower to get rid of slagging in central heating boilers, however the cleaning 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 also lower the softening temperature to 800 ℃, which is in the range of superheater. So the soften ash is simple to affix to the heat wall surface and also difficult to be eliminated by steam residue blower



Besides, heavy steam residue blowers has complying with negative aspects. The central heating boilers cleaned up by vapor residue blower need to wait for 15 days for following use. The removing area is restricted, with some dead angles. As the residue blowing period is long, there are too much ash deposited in the heating surface area. They might sintered and set, as well as enhance the cleansing difficulties.



defocusing prevention and also pulse gas ash blower.

Nowadays, lots of biomass central heating boilers take on defocusing inhibitor as well as pulse gas ash blower to resolve biomass central heating boiler slagging and also accomplished remarkable effect.



Defocusing inhibitor is a gas additive with high melting point as well as burning improver. When it is splashed right into the hearth, it will certainly combine with fly ash as well as stay with the half-melt ash. It will change the melting point of ash and ruin slagging. It can likewise develop metal film on the pipe surface area to stop acid dew point deterioration.



Pulse gas ash blower can get rid of the ash deposit on the boiler home heating surface area by removing, acoustic tiredness, thermal cleansing and also regional resonance. At last, the gas flow eliminate the ash.



Select the most effective method to address slagging trouble

To use excellent quality biomass fuels in boilers can minimize slagging, but the expense will raise. If you have to make use of low quality biomass fuels, which has high moisture and impurities material, slagging is unpreventable. To ensure the stable running of boilers, you can combine defocusing prevention as well as pulse gas ash blower to successfully solve the slagging trouble.
