How to solve the slagging of biomass boilers
How to resolve the slagging of biomass boilers?
Biomass boilers embraces biomass wastes or biomass pellets as fuel. In the burning of pellet gas, the volatiles turn into gas and have complicated response with smoke and dirt, coagulate and also adhere to the heating pipeline surface. The slagging and ash down payment will certainly influence the operation and safety of central heating boilers. In this write-up, I will evaluate the features of slagging, learn the factor of biomass boiler slagging, as well as advanced effective options.

Factors for biomass boiler slagging
The slagging of biomass boilers describes the ash created in the burning of biomass fuel. At high temperature, the ash remains in liquid or soft solid condition. Once they touch the home heating surface, they would abide by it and also develop right into slag.

Biomass gas make-up as well as ecological tool
The ash melting point is impacted by the make-up of biomass fuel and also environmental tool. If there are incompletely combusted fuels, they will certainly make the environmental medium weakly reductive, as well as lower the melting point. Under this problem, the ash are easy to affix to the hearth and also the wall surface of superheater. If the biomass fuel has high moisture material, the vapor will soften potassium, which is the major web content in ash.

Contaminations in biomass fuels create slagging
A large part of biomass gas are made by more than 1 raw material. In some cases they are combined with dirt as well as sand. These contaminations altered the structure as well as melting temperature of biomass gas. With high ash and also alkali metal web content, these impure biomass gas are less complicated to trigger slagging.

Inadequate air in central heating boilers for burning
Sometimes the biomass fuels are dispersed erratically in central heating boilers. They end up being heat burning mass and also melt with inadequate oxygen, which will create slagging. Insufficient ventilation quantity will certainly raise the slagging level. Therefore, to avoid biomass central heating boiler slagging, you ought to manage the proportion of fuel and also air.


You can readjust the air proportion by getting rid of some fuels. Besides, slagging might develop from boiler problems. The feeding device can create fuel piling and also worsen slagging.

Uneven heat circulation of central heating boiler surface area
The central heating boiler inside temperature level as well as warm distribution have terrific effect on the slagging. As experience shows, slagging generally appears in flue and superheater surface. When the liquid or soft solid ash approach the heating surface area, it do not have enough time to cool off, so it is very easy to comply with the home heating surface and gather. As looks into verified, the higher the central heating boiler temperature, the even more slagging. Slagging influence the warmth exchange of central heating boiler surface area, obstruct the flue, raise the smoke flow speed, and intensify the home heating surface wear.

Just how to fix the slagging of biomass central heating boilers?
Currently we understand the slagging of biomass boilers emerges from the biomass gas properties as well as boiler style. To lower the slagging, we should pick excellent quality biomass pellets and also high-efficiency boilers, and regulate the feeding rate. Yet you can not eradicate slagging completely. You require to clean up the biomass central heating boilers consistently.

Vapor soot blower
Typically, they utilize steam residue blower to get rid of slagging in central heating boilers, however the cleaning result is barely adequate. rabbit feed pellet making machine have to clean the central heating boiler with high-pressure water.

The potassium in biomass fuel create silicon in burning as well as reduced the softening temperature level to 800 ℃, which is in the range of superheater. So straw pellet machine for sale soften ash is very easy to affix to the heat wall surface as well as difficult to be gotten rid of by steam soot blower

Besides, heavy steam residue blowers has complying with negative aspects. The boilers cleaned up by steam residue blower have to wait on 15 days for next use. The purging area is limited, with some dead angles. As the soot blowing interval is long, there are way too much ash transferred in the heating surface area. They may sintered as well as solidify, as well as boost the cleaning troubles.

defocusing prevention as well as pulse gas ash blower.
Nowadays, many biomass central heating boilers embrace defocusing inhibitor and pulse gas ash blower to resolve biomass central heating boiler slagging as well as attained impressive result.

Defocusing prevention is a gas additive with high melting point and also combustion improver. When it is splashed right into the hearth, it will certainly mix with fly ash and adhere to the half-melt ash. It will change the melting point of ash and destroy slagging. It can also develop metal film on the pipe surface to avoid acid dew point rust.

Pulse gas ash blower can remove the ash down payment on the boiler home heating surface area by removing, acoustic tiredness, thermal cleaning and also regional vibration. At last, the gas flow take away the ash.

Choose the best way to fix slagging issue
To make use of top quality biomass fuels in central heating boilers can lower slagging, yet the cost will raise. If you need to utilize poor quality biomass fuels, which has high moisture and also pollutants content, slagging is inevitable. To ensure the stable running of central heating boilers, you can incorporate defocusing inhibitor and pulse gas ash blower to efficiently solve the slagging trouble.
