Just how to resolve the slagging of biomass boilers?<br>
Biomass central heating boilers takes on biomass wastes or biomass pellets as fuel. In the burning of pellet gas, the volatiles develop into gas and have actually complicated response with smoke and dirt, coagulate and also adhere to the home heating pipe surface area. The slagging and ash down payment will certainly affect the operation and also security of boilers. In this article, I will certainly analyze the attributes of slagging, discover the reason of biomass central heating boiler slagging, and also advanced efficient solutions.



Reasons for biomass boiler slagging

The slagging of biomass central heating boilers describes the ash generated in the burning of biomass fuel. At high temperature, the ash remains in fluid or soft solid standing. Once they touch the heating surface, they would abide by it as well as form right into slag.



Biomass fuel make-up and ecological medium

The ash melting point is impacted by the structure of biomass fuel and also environmental medium. If there are incompletely combusted fuels, they will make the environmental tool weakly reductive, and lower the melting point. Under this condition, the ash are simple to attach to the hearth as well as the wall of superheater. If the biomass gas has high moisture content, the vapor will certainly soften potassium, which is the major material in ash.



Impurities in biomass gas trigger slagging

A big part of biomass fuels are made by more than 1 resources. Sometimes they are combined with dirt and also sand. These pollutants transformed the structure as well as melting temperature level of biomass fuels. With high ash and alkali steel web content, these impure biomass fuels are easier to trigger slagging.



Not enough air in central heating boilers for burning


Sometimes the biomass fuels are dispersed unevenly in boilers. They end up being heat combustion mass as well as shed with not enough oxygen, which will create slagging. Insufficient ventilation quantity will raise the slagging level. Consequently, to stay clear of biomass central heating boiler slagging, you should control the percentage of fuel and also air.



You can readjust the air percentage by removing some gas. Besides, slagging might arise from central heating boiler troubles. The feeding device can cause fuel stacking as well as exacerbate slagging.



Irregular warmth circulation of boiler surface

The boiler inside temperature level and also warmth circulation have wonderful impact on the slagging. As experience programs, slagging usually shows up in flue as well as superheater surface. When the liquid or soft solid ash move toward the heating surface, it don't have enough time to cool, so it is simple to comply with the home heating surface area as well as collect. As researches confirmed, the higher the boiler temperature, the even more slagging. Slagging influence the heat exchange of central heating boiler surface area, obstruct the flue, increase the smoke flow rate, and exacerbate the home heating surface wear.



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

Now we know the slagging of biomass boilers emerges from the biomass gas buildings and also central heating boiler layout. To decrease the slagging, we need to choose premium quality biomass pellets as well as high-efficiency boilers, as well as regulate the feeding speed. But you can not eliminate slagging entirely. You require to clean up the biomass central heating boilers consistently.



Steam soot blower

Typically, they make use of heavy steam soot blower to get rid of slagging in central heating boilers, yet the cleansing impact is hardly adequate. They have to clean the central heating boiler with high-pressure water.



The potassium in biomass fuel produce silicon in burning and also lower the softening temperature to 800 ℃, which remains in the variety of superheater. So the soften ash is very easy to affix to the heat wall and also difficult to be gotten rid of by steam soot blower



Besides, vapor soot blowers has following disadvantages. The central heating boilers cleaned up by steam residue blower have to wait for 15 days for following use. The purging location is limited, with some dead angles. As the residue blowing interval is long, there are way too much ash deposited in the heating surface area. They might sintered and harden, and increase the cleansing troubles.



defocusing inhibitor and pulse gas ash blower.

Nowadays, lots of biomass boilers embrace defocusing prevention and pulse gas ash blower to fix biomass central heating boiler slagging and achieved remarkable effect.



Defocusing inhibitor is a fuel additive with high melting point and burning improver. When it is splashed into the fireplace, it will combine with fly ash and adhere to the half-melt ash. It will alter the melting point of ash and destroy slagging. richi pellet mill can additionally create metal movie on the pipeline surface to avoid acid dew point corrosion.



Pulse gas ash blower can clear the ash deposit on the boiler heating surface by purging, acoustic fatigue, thermal cleansing and also neighborhood resonance. At floating fish feed machine price , the gas flow remove the ash.



Select the very best means to address slagging problem

To make use of top quality biomass fuels in boilers can lower slagging, but the price will boost. If you need to utilize low quality biomass fuels, which has high dampness and impurities web content, slagging is inescapable. To make certain the secure running of central heating boilers, you can incorporate defocusing prevention as well as pulse gas ash blower to efficiently address the slagging trouble.
