Exactly how to solve the slagging of biomass central heating boilers?<br>
Biomass boilers adopts biomass wastes or biomass pellets as fuel. In the burning of pellet gas, the volatiles become gas and also have made complex reaction with smoke as well as dirt, coagulate as well as stick to the home heating pipeline surface area. The slagging as well as ash deposit will certainly impact the operation as well as safety of boilers. In this post, I will analyze the functions of slagging, figure out the factor of biomass central heating boiler slagging, and put forward effective remedies.



Reasons for biomass central heating boiler slagging

The slagging of biomass central heating boilers describes the ash created in the burning of biomass fuel. At high temperature, the ash is in liquid or soft strong standing. Once they touch the heating surface, they would certainly abide by it as well as create into slag.



Biomass fuel structure and also environmental tool

The ash melting point is influenced by the make-up of biomass fuel and environmental medium. If there are incompletely ignited fuels, they will certainly make the ecological medium weakly reductive, and reduced the melting point. Under this problem, the ash are simple to affix to the hearth and the wall surface of superheater. If richi pellet machine has high wetness content, the vapor will certainly soften potassium, which is the major web content in ash.



Contaminations in biomass gas cause slagging

A huge part of biomass gas are made by more than 1 basic material. Occasionally they are combined with dust as well as sand. These pollutants altered the structure and melting temperature level of biomass gas. With high ash and alkali steel content, these unclean biomass gas are easier to trigger slagging.



Not enough air in central heating boilers for burning

Sometimes the biomass gas are distributed unevenly in central heating boilers. They become high temperature burning mass as well as burn with insufficient oxygen, which will certainly cause slagging. Insufficient air flow quantity will certainly boost the slagging degree. Consequently, to stay clear of biomass central heating boiler slagging, you ought to regulate the percentage of fuel as well as air.



You can change the air percentage by eliminating some gas. Besides, slagging may emerge from central heating boiler troubles. The feeding gadget can cause fuel stacking as well as exacerbate slagging.



Unequal warm circulation of central heating boiler surface

The boiler inside temperature and also warm circulation have fantastic influence on the slagging. As experience programs, slagging generally appears in flue as well as superheater surface area. When second hand pellet mill or soft solid ash approach the heating surface, it don't have sufficient time to cool down, so it is easy to comply with the heating surface and also accumulate. As looks into verified, the greater the central heating boiler temperature, the even more slagging. Slagging impact the warmth exchange of central heating boiler surface area, block the flue, increase the smoke flow rate, as well as worsen the heating surface wear.



Just how to resolve the slagging of biomass central heating boilers?

Currently we know the slagging of biomass boilers develops from the biomass fuel buildings and central heating boiler design. To decrease the slagging, we must pick premium quality biomass pellets as well as high-efficiency central heating boilers, as well as regulate the feeding speed. But you can't get rid of slagging totally. You require to clean the biomass boilers regularly.



Vapor residue blower


Typically, they use vapor soot blower to eliminate slagging in central heating boilers, however the cleansing impact is barely sufficient. They 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 to 800 ℃, which remains in the range of superheater. So the soften ash is simple to connect to the heat wall as well as difficult to be eliminated by heavy steam residue blower



Besides, vapor soot blowers has adhering to negative aspects. The central heating boilers cleaned up by steam residue blower need to wait on 15 days for next usage. The purging location is limited, with some dead angles. As the residue blowing interval is long, there are too much ash transferred in the heating surface. They may sintered and harden, and also raise the cleansing difficulties.



defocusing inhibitor and pulse gas ash blower.

Nowadays, many biomass boilers take on defocusing inhibitor and pulse gas ash blower to address biomass boiler slagging as well as accomplished exceptional impact.



Defocusing inhibitor is a fuel additive with high melting point and also burning improver. When it is splashed right into the hearth, it will certainly mix with fly ash and also stick to the half-melt ash. It will certainly transform the melting point of ash and destroy slagging. It can additionally create steel film on the pipeline surface area to avoid acid dew point corrosion.



Pulse gas ash blower can clear the ash down payment on the central heating boiler home heating surface area by purging, acoustic exhaustion, thermal cleansing and also neighborhood resonance. Finally, the gas flow take away the ash.



Choose the best way to solve slagging problem

To use premium quality biomass fuels in central heating boilers can reduce slagging, but the expense will certainly raise. If you have to utilize poor quality biomass fuels, which has high wetness as well as contaminations material, slagging is inevitable. To make sure the stable running of central heating boilers, you can integrate defocusing prevention and also pulse gas ash blower to properly solve the slagging issue.
