Exactly how to solve the slagging of biomass central heating boilers?<br>
Biomass central heating boilers embraces biomass wastes or biomass pellets as fuel. In the burning of pellet fuels, the volatiles turn into gas as well as have actually made complex response with smoke as well as dirt, coagulate and abide by the home heating pipe surface. The slagging and also ash down payment will affect the procedure and safety and security of central heating boilers. In this article, I will analyze the attributes of slagging, figure out the factor of biomass central heating boiler slagging, and advanced efficient solutions.



Reasons for biomass boiler slagging

The slagging of biomass boilers refers to the ash produced in the burning of biomass gas. At heat, the ash remains in fluid or soft strong standing. Once they touch the heating surface area, they would abide by it as well as create into slag.



Biomass fuel structure and ecological medium

The ash melting point is affected by the structure of biomass fuel and environmental medium. If there are incompletely ignited fuels, small feed pellet machine price will make the environmental medium weakly reductive, and lower the melting point. Under this problem, the ash are simple to connect to the hearth and the wall surface of superheater. If the biomass fuel has high wetness content, the heavy steam will certainly soften potassium, which is the significant web content in ash.



Contaminations in biomass fuels create slagging

A big part of biomass fuels are made by greater than 1 basic material. Sometimes they are blended with dust as well as sand. These pollutants transformed the composition and melting temperature level of biomass gas. With high ash and alkali steel web content, these impure biomass fuels are simpler to trigger slagging.



Not enough air in central heating boilers for burning


Often the biomass fuels are dispersed erratically in boilers. They come to be high temperature burning mass and also shed with insufficient oxygen, which will certainly cause slagging. Not enough ventilation amount will certainly enhance the slagging level. Therefore, to prevent biomass central heating boiler slagging, you need to manage the percentage of gas as well as air.



You can readjust the air percentage by eliminating some fuels. Besides, slagging might emerge from boiler problems. chicken pellet machine feeding tool can cause gas stacking and worsen slagging.



Uneven warmth distribution of boiler surface

The central heating boiler inside temperature level as well as warm circulation have excellent effect on the slagging. As experience shows, slagging usually shows up in flue as well as superheater surface area. When the fluid or soft solid ash approach the heating surface, it don't have sufficient time to cool off, so it is very easy to adhere to the home heating surface and also collect. As researches confirmed, the greater the boiler temperature, the even more slagging. Slagging affect the warm exchange of boiler surface, obstruct the flue, increase the smoke flow speed, as well as worsen the heating surface wear.



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

Now we know the slagging of biomass central heating boilers emerges from the biomass fuel buildings and also central heating boiler layout. To decrease the slagging, we need to select premium quality biomass pellets and high-efficiency central heating boilers, and also manage the feeding speed. However you can't eliminate slagging totally. You need to clean the biomass central heating boilers frequently.



Heavy steam residue blower

Commonly, they use vapor soot blower to remove slagging in central heating boilers, yet the cleansing impact is hardly satisfactory. They have 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 series of superheater. So the soften ash is simple to attach to the warm wall surface and also tough to be removed by steam soot blower



Besides, heavy steam residue blowers has following disadvantages. The central heating boilers cleaned up by vapor soot blower need to await 15 days for next usage. The removing area is restricted, with some dead angles. As the soot blowing period is long, there are way too much ash transferred in the home heating surface area. They may sintered and solidify, as well as raise the cleaning troubles.



defocusing prevention as well as pulse gas ash blower.

Nowadays, numerous biomass boilers embrace defocusing prevention as well as pulse gas ash blower to solve biomass boiler slagging as well as accomplished impressive result.



Defocusing inhibitor is a fuel additive with high melting point and also combustion improver. When it is sprayed into the fireplace, it will blend with fly ash and adhere to the half-melt ash. It will change the melting point of ash and also ruin slagging. It can likewise develop steel film on the pipe surface area to stop acid humidity rust.



Pulse gas ash blower can remove the ash deposit on the central heating boiler heating surface by purging, acoustic fatigue, thermal cleansing and also local resonance. At last, the gas flow eliminate the ash.



Select the best way to solve slagging issue

To make use of high quality biomass gas in central heating boilers can minimize slagging, yet the price will boost. If you have to make use of low quality biomass fuels, which has high dampness as well as pollutants content, slagging is inevitable. To guarantee the secure operating of boilers, you can incorporate defocusing inhibitor and also pulse gas ash blower to properly solve the slagging problem.
