Just how to solve the slagging of biomass central heating boilers?<br>
Biomass boilers embraces biomass wastes or biomass pellets as gas. In the burning of pellet gas, the volatiles become gas as well as have complicated response with smoke and also dust, coagulate as well as comply with the home heating pipe surface area. The slagging and ash deposit will certainly impact the operation as well as safety and security of central heating boilers. In this article, I will assess the functions of slagging, find out the reason of biomass boiler slagging, and also advanced efficient options.



Reasons for biomass boiler slagging

The slagging of biomass central heating boilers describes the ash produced in the burning of biomass fuel. At high temperature, the ash is in liquid or soft strong status. Once they touch the home heating surface area, they would adhere to it and develop into slag.



Biomass gas structure and also environmental medium

The ash melting point is impacted by the composition of biomass gas and also environmental medium. If there are incompletely combusted fuels, they will make the environmental medium weakly reductive, and reduced the melting point. Under used pellet making machines for sale , the ash are very easy to affix to the fireplace as well as the wall surface of superheater. If the biomass fuel has high moisture content, the vapor will certainly soften potassium, which is the major content in ash.



Contaminations in biomass fuels trigger slagging

A big part of biomass gas are made by greater than 1 resources. Often they are mixed with dirt and sand. These impurities changed the composition and also melting temperature of biomass gas. With high ash and also alkali steel content, these unclean biomass gas are much easier to cause slagging.




Inadequate air in boilers for burning

Often the biomass gas are dispersed unevenly in central heating boilers. They come to be high temperature burning mass as well as burn with inadequate oxygen, which will certainly trigger slagging. Inadequate air flow amount will certainly enhance the slagging degree. As a result, to stay clear of biomass boiler slagging, you should control the percentage of fuel and air.



You can adjust the air percentage by removing some fuels. Besides, slagging might emerge from central heating boiler issues. The feeding tool can trigger fuel stacking and worsen slagging.



Unequal warmth distribution of boiler surface area

The boiler inside temperature level as well as warm circulation have excellent influence on the slagging. As experience shows, slagging typically appears in flue and superheater surface. When richi pellet machine or soft solid ash move toward the heating surface, it do not have enough time to cool, so it is very easy to adhere to the heating surface and also gather. As looks into proved, the higher the central heating boiler temperature, the more slagging. Slagging influence the warmth exchange of central heating boiler surface, block the flue, enhance the smoke flow speed, and also worsen the heating surface wear.



How to solve the slagging of biomass central heating boilers?

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



Heavy steam soot blower

Commonly, they use vapor soot blower to eliminate slagging in central heating boilers, but the cleaning effect is barely sufficient. They have to clean the central heating boiler with high-pressure water.



The potassium in biomass fuel generate silicon in burning and reduced the softening temperature level to 800 ℃, which remains in the series of superheater. So the soften ash is easy to connect to the warmth wall and also difficult to be gotten rid of by heavy steam residue blower



Besides, vapor residue blowers has complying with disadvantages. The central heating boilers cleansed by vapor soot blower need to wait on 15 days for following use. The removing area is limited, with some dead angles. As the soot blowing interval is long, there are excessive ash deposited in the home heating surface area. They may sintered as well as harden, as well as raise the cleansing troubles.



defocusing inhibitor as well as pulse gas ash blower.

Nowadays, many biomass central heating boilers embrace defocusing inhibitor and pulse gas ash blower to fix biomass central heating boiler slagging and attained impressive effect.



Defocusing prevention is a fuel additive with high melting point as well as combustion improver. When it is splashed into the fireplace, it will certainly blend with fly ash as well as stay with the half-melt ash. It will certainly change the melting point of ash and also destroy slagging. It can additionally develop steel film on the pipe surface area to avoid acid humidity rust.



Pulse gas ash blower can remove the ash down payment on the boiler heating surface by removing, acoustic exhaustion, thermal cleansing and neighborhood vibration. At last, the gas circulation take away the ash.



Pick the most effective method to address slagging trouble

To utilize high quality biomass gas in central heating boilers can lower slagging, but the expense will raise. If you need to utilize poor quality biomass fuels, which has high dampness as well as pollutants content, slagging is unavoidable. To ensure the secure running of central heating boilers, you can combine defocusing prevention and also pulse gas ash blower to successfully address the slagging issue.
