How to fix the slagging of biomass central heating boilers?<br>
Biomass central heating boilers takes on biomass wastes or biomass pellets as fuel. In the burning of pellet fuels, the volatiles turn into gas and have actually made complex reaction with smoke and also dust, coagulate and also follow the heating pipeline surface area. The slagging and ash deposit will affect the procedure as well as safety of central heating boilers. In this article, I will assess the functions of slagging, learn the reason of biomass central heating boiler slagging, as well as advanced effective services.



Reasons for biomass boiler slagging

The slagging of biomass central heating boilers describes the ash created in the burning of biomass fuel. At high temperature, the ash remains in fluid or soft strong status. Once they touch the heating surface, they would certainly comply with it and form right into slag.



Biomass fuel composition and environmental medium

The ash melting point is impacted by the composition of biomass gas as well as environmental tool. If there are incompletely combusted fuels, they will certainly make the ecological tool weakly reductive, and lower the melting point. Under this problem, the ash are easy to connect to the hearth as well as the wall of superheater. If the biomass gas has high dampness web content, the steam will certainly soften potassium, which is the major content in ash.



Pollutants in biomass fuels create slagging

A huge part of biomass fuels are made by more than 1 resources. In some cases they are combined with dust and sand. These pollutants changed the composition as well as melting temperature level of biomass fuels. With high ash and alkali steel content, these impure biomass gas are less complicated to trigger slagging.



Insufficient air in central heating boilers for burning

Occasionally the biomass gas are dispersed erratically in central heating boilers. They come to be heat combustion mass and burn with not enough oxygen, which will certainly trigger slagging. Inadequate ventilation quantity will raise the slagging level. As a result, to avoid biomass boiler slagging, you must control the percentage of fuel as well as air.



You can readjust the air percentage by eliminating some gas. Besides, slagging might emerge from boiler problems. The feeding gadget can trigger fuel piling as well as aggravate slagging.



Irregular heat distribution of central heating boiler surface area

The boiler inside temperature as well as heat distribution have wonderful influence on the slagging. As experience shows, slagging generally shows up in flue and superheater surface. When the fluid or soft solid ash approach the heating surface area, it don't have sufficient time to cool, so it is easy to adhere to the heating surface area and collect. As investigates verified, the higher the central heating boiler temperature, the more slagging. Slagging impact the warmth exchange of central heating boiler surface, obstruct the flue, raise the smoke flow rate, as well as intensify the heating surface area wear.



How to fix the slagging of biomass central heating boilers?

Now we understand the slagging of biomass central heating boilers emerges from the biomass fuel properties and central heating boiler style. To decrease the slagging, we must choose premium quality biomass pellets as well as high-efficiency central heating boilers, as well as control the feeding rate. But you can not eliminate slagging entirely. https://carmenpelletmachine.weblog.to/archives/22313030.html need to clean up the biomass central heating boilers on a regular basis.



Vapor soot blower

Typically, they use vapor residue blower to get rid of slagging in boilers, however the cleansing result is barely acceptable. richi pellet machine need to wash the central heating boiler with high-pressure water.



The potassium in biomass gas create silicon in burning and also lower the softening temperature to 800 ℃, which is in the series of superheater. So the soften ash is easy to affix to the warmth wall surface as well as hard to be eliminated by steam soot blower



Besides, vapor soot blowers has following negative aspects. The central heating boilers cleansed by steam residue blower need to await 15 days for next use. The removing location is restricted, with some dead angles. As the soot blowing period is long, there are excessive ash deposited in the heating surface. They may sintered as well as solidify, and raise the cleansing problems.



defocusing inhibitor and also pulse gas ash blower.


Nowadays, lots of biomass central heating boilers embrace defocusing prevention as well as pulse gas ash blower to solve biomass boiler slagging and also achieved remarkable result.



Defocusing prevention is a gas additive with high melting point and also burning improver. When it is sprayed into the fireplace, it will certainly blend with fly ash as well as stick to the half-melt ash. It will change the melting point of ash and also destroy slagging. richi pellet machine can additionally develop metal movie on the pipe surface to prevent acid humidity corrosion.



Pulse gas ash blower can get rid of the ash down payment on the central heating boiler heating surface area by purging, acoustic tiredness, thermal cleansing and local vibration. Finally, the gas flow eliminate the ash.



Pick the most effective method to resolve slagging problem

To utilize excellent quality biomass fuels in boilers can decrease slagging, however the cost will increase. If you need to use low quality biomass gas, which has high dampness and contaminations material, slagging is unavoidable. To ensure the steady running of central heating boilers, you can integrate defocusing prevention as well as pulse gas ash blower to efficiently fix the slagging problem.
