How to solve the slagging of biomass boilers
How to solve the slagging of biomass central heating boilers?
Biomass central heating boilers adopts biomass wastes or biomass pellets as gas. In the burning of pellet gas, the volatiles turn into gas as well as have actually made complex reaction with smoke as well as dust, coagulate and also stick to the heating pipe surface. The slagging and ash down payment will certainly impact the procedure as well as safety of central heating boilers. In this post, I will certainly analyze the features of slagging, find out the factor of biomass boiler slagging, as well as put forward efficient options.


Factors for biomass central heating boiler slagging
The slagging of biomass central heating boilers refers to the ash produced in the burning of biomass fuel. At heat, the ash is in liquid or soft strong condition. Once they touch the home heating surface area, they would certainly stick to it as well as form right into slag.

Biomass fuel make-up and ecological tool

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

Pollutants in biomass gas cause slagging
A huge part of biomass fuels are made by more than 1 basic material. In some cases they are blended with dust and sand. These impurities altered the structure and melting temperature of biomass gas. With high ash and alkali steel web content, these impure biomass gas are easier to trigger slagging.

Not enough air in central heating boilers for burning
Often the biomass gas are distributed erratically in central heating boilers. They come to be heat combustion mass and burn with insufficient oxygen, which will certainly create slagging. Inadequate ventilation amount will certainly boost the slagging level. Therefore, to prevent biomass central heating boiler slagging, you need to control the percentage of gas as well as air.

You can readjust the air percentage by removing some fuels. Besides, slagging may arise from central heating boiler troubles. The feeding gadget can cause fuel stacking as well as worsen slagging.

Unequal heat circulation of central heating boiler surface
The boiler inside temperature as well as heat circulation have wonderful impact on the slagging. As experience programs, slagging usually appears in flue as well as superheater surface area. When the fluid or soft strong ash move toward the home heating surface area, it do not have adequate time to cool down, so it is very easy to abide by the home heating surface area and also accumulate. As looks into proved, price of poultry feed making machine , the more slagging. Slagging impact the heat exchange of boiler surface area, obstruct the flue, raise the smoke flow rate, as well as aggravate the heating surface wear.

Just how to address the slagging of biomass boilers?
Currently we understand the slagging of biomass boilers occurs from the biomass gas properties as well as central heating boiler style. To lower the slagging, we must pick premium quality biomass pellets and also high-efficiency boilers, and manage the feeding rate. Yet you can't get rid of slagging completely. You require to cleanse the biomass boilers frequently.

Steam residue blower
Typically, they use heavy steam soot blower to remove slagging in boilers, however the cleaning effect is hardly sufficient. They have to wash the boiler with high-pressure water.

The potassium in biomass fuel generate silicon in burning and lower the softening temperature level to 800 ℃, which is in the variety of superheater. So the soften ash is simple to attach to the warmth wall surface as well as difficult to be eliminated by vapor soot blower

Besides, steam soot blowers has following disadvantages. The central heating boilers cleaned up by vapor residue blower need to wait on 15 days for next use. The removing area is restricted, with some dead angles. As the soot blowing interval is long, there are too much ash transferred in the heating surface. They might sintered and set, and enhance the cleansing difficulties.

defocusing prevention as well as pulse gas ash blower.
Nowadays, straw pellet mill of biomass boilers embrace defocusing prevention and pulse gas ash blower to solve biomass central heating boiler slagging as well as accomplished remarkable impact.

Defocusing prevention is a gas additive with high melting point and also burning improver. When it is splashed into the fireplace, it will certainly blend with fly ash and also adhere to the half-melt ash. It will certainly change the melting point of ash and destroy slagging. It can also develop steel film on the pipeline surface area to stop acid dew point corrosion.

Pulse gas ash blower can remove the ash deposit on the central heating boiler heating surface by removing, acoustic fatigue, thermal cleaning as well as neighborhood vibration. Finally, the gas circulation take away the ash.

Choose the most effective way to solve slagging trouble
To use premium quality biomass gas in central heating boilers can reduce slagging, but the price will boost. If you need to make use of low quality biomass gas, which has high dampness and impurities material, slagging is inevitable. To make sure the steady running of central heating boilers, you can incorporate defocusing prevention as well as pulse gas ash blower to successfully fix the slagging problem.
