How to resolve the slagging of biomass central heating boilers?<br>
Biomass central heating boilers adopts biomass wastes or biomass pellets as fuel. In the burning of pellet gas, the volatiles develop into gas and also have complicated response with smoke and dirt, coagulate as well as stick to the home heating pipeline surface area. The slagging as well as ash down payment will affect the procedure and also safety and security of boilers. In this post, I will analyze the functions of slagging, learn the factor of biomass central heating boiler slagging, as well as put forward effective services.



Reasons for biomass central heating boiler slagging

The slagging of biomass boilers refers to the ash generated in the burning of biomass gas. At high temperature, the ash remains in fluid or soft solid status. Once they touch the home heating surface area, they would adhere to it and also form into slag.



Biomass gas composition as well as ecological medium

The ash melting point is affected by the structure of biomass fuel as well as environmental medium. If there are incompletely combusted homemade chicken feed machine , they will make the environmental medium weakly reductive, and also reduced the melting point. Under this problem, the ash are simple to affix to the fireplace as well as the wall of superheater. If the biomass fuel has high moisture material, the heavy steam will soften potassium, which is the major content in ash.




Contaminations in biomass gas trigger slagging

A big part of biomass fuels are made by greater than 1 raw material. Often they are blended with dirt and also sand. These contaminations altered the make-up as well as melting temperature of biomass gas. With high ash and also alkali metal content, these impure biomass fuels are much easier to cause slagging.



Not enough air in central heating boilers for burning

Often the biomass fuels are distributed unevenly in central heating boilers. They come to be high temperature combustion mass as well as melt with inadequate oxygen, which will certainly create slagging. Insufficient ventilation quantity will boost the slagging level. Consequently, to prevent biomass boiler slagging, you should manage the proportion of gas as well as air.



You can readjust the air percentage by eliminating some fuels. Besides, slagging might develop from central heating boiler problems. The feeding tool can trigger gas stacking as well as worsen slagging.



Unequal heat circulation of central heating boiler surface

The boiler inside temperature level and also warmth circulation have great effect on the slagging. As experience programs, slagging typically appears in flue as well as superheater surface. When the fluid or soft solid ash move toward the heating surface area, 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 investigates shown, the greater the central heating boiler temperature level, the even more slagging. Slagging rabbit pellet making machine of central heating boiler surface area, block the flue, boost the smoke flow rate, as well as aggravate the home heating surface wear.



Exactly how to address the slagging of biomass boilers?

Currently we know the slagging of biomass boilers occurs from the biomass fuel residential or commercial properties as well as central heating boiler design. To reduce the slagging, we need to choose high quality biomass pellets as well as high-efficiency boilers, as well as control the feeding rate. However you can not get rid of slagging completely. You require to clean the biomass central heating boilers regularly.



Vapor soot blower

Generally, they use heavy steam soot blower to eliminate slagging in boilers, however the cleaning impact is hardly satisfying. They need to wash the boiler with high-pressure water.



The potassium in biomass gas produce silicon in burning as well as lower the softening temperature to 800 ℃, which is in the range of superheater. So the soften ash is very easy to affix to the heat wall surface and tough to be removed by vapor residue blower



Besides, vapor residue blowers has following downsides. The boilers cleaned up by steam residue blower need to await 15 days for next usage. The removing location is restricted, with some dead angles. As the soot blowing period is long, there are way too much ash deposited in the heating surface. They might sintered and solidify, and also boost the cleaning troubles.



defocusing prevention and pulse gas ash blower.

Nowadays, numerous biomass boilers adopt defocusing inhibitor and also pulse gas ash blower to address biomass boiler slagging and also attained amazing impact.



Defocusing prevention is a fuel additive with high melting point and burning improver. When it is sprayed right 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 also damage slagging. It can additionally form metal movie on the pipeline surface area to avoid acid dew point rust.



Pulse gas ash blower can clear the ash deposit on the boiler heating surface by purging, acoustic tiredness, thermal cleaning and also neighborhood vibration. Finally, the gas circulation eliminate the ash.



Select the very best means to fix slagging problem

To utilize top quality biomass fuels in central heating boilers can lower slagging, yet the cost will certainly raise. If you need to use low quality biomass gas, which has high wetness as well as pollutants material, slagging is unavoidable. To make sure the steady operating of central heating boilers, you can combine defocusing inhibitor and pulse gas ash blower to properly fix the slagging issue.
