How to solve the slagging of biomass boilers?<br>
Biomass central heating boilers embraces biomass wastes or biomass pellets as fuel. In the burning of pellet fuels, the volatiles turn into gas as well as have made complex reaction with smoke and also dirt, coagulate as well as stick to the heating pipeline surface area. The slagging and ash deposit will influence the procedure as well as security of central heating boilers. In cow dung pellet making machine , I will examine the functions of slagging, discover the reason of biomass central heating boiler slagging, and also put forward effective options.



Factors for biomass central heating boiler slagging

The slagging of biomass boilers refers to the ash created in the burning of biomass gas. At high temperature, the ash is in liquid or soft strong standing. Once they touch the home heating surface area, they would follow it and create right into slag.



Biomass fuel structure as well as ecological tool

The ash melting point is affected by the make-up of biomass gas as well as environmental medium. If there are incompletely ignited gas, they will certainly make the environmental tool weakly reductive, and lower the melting point. Under this problem, the ash are simple to connect to the fireplace and also the wall of superheater. If the biomass gas has high dampness web content, the vapor will certainly soften potassium, which is the major material in ash.



Pollutants in biomass gas create slagging

A huge part of biomass gas are made by more than 1 basic material. Sometimes they are blended with dirt as well as sand. These pollutants changed the make-up and also melting temperature level of biomass gas. With price of poultry feed making machine and alkali steel web content, these impure biomass fuels are simpler to create slagging.




Not enough air in central heating boilers for burning

Sometimes the biomass fuels are distributed erratically in central heating boilers. They come to be high temperature combustion mass and also melt with insufficient oxygen, which will create slagging. Not enough ventilation amount will certainly increase the slagging degree. For that reason, to stay clear of biomass boiler slagging, you need to control the percentage of fuel and also air.



You can readjust the air percentage by getting rid of some gas. Besides, slagging might emerge from central heating boiler issues. The feeding device can create fuel piling as well as intensify slagging.



Irregular warmth distribution of central heating boiler surface area

The central heating boiler inside temperature and warm circulation have great impact on the slagging. As experience programs, slagging normally appears in flue as well as superheater surface. When the fluid or soft strong ash approach the heating surface, it don't have enough time to cool off, so it is simple to abide by the heating surface area and build up. As researches verified, the higher the central heating boiler temperature level, the even more slagging. Slagging influence the warm exchange of central heating boiler surface area, block the flue, increase the smoke circulation rate, and aggravate the heating surface wear.



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

Now we know the slagging of biomass boilers emerges from the biomass gas residential properties and central heating boiler style. To lower the slagging, we should pick excellent quality biomass pellets and high-efficiency central heating boilers, as well as control the feeding speed. However you can not get rid of slagging completely. You need to clean the biomass boilers consistently.



Vapor soot blower

Commonly, they utilize steam residue blower to remove slagging in central heating boilers, but the cleansing impact is barely satisfactory. They need to wash the central heating boiler with high-pressure water.



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



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



defocusing prevention and pulse gas ash blower.

Nowadays, many biomass central heating boilers adopt defocusing prevention and also pulse gas ash blower to fix biomass central heating boiler slagging and also attained remarkable effect.



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



Pulse gas ash blower can clear the ash down payment on the boiler home heating surface area by removing, acoustic tiredness, thermal cleaning and neighborhood vibration. Finally, the gas flow eliminate the ash.



Select the most effective means to address slagging issue

To utilize top quality biomass gas in central heating boilers can minimize slagging, but the price will raise. If you have to make use of poor quality biomass fuels, which has high moisture as well as pollutants content, slagging is inescapable. To ensure the secure running of central heating boilers, you can combine defocusing inhibitor as well as pulse gas ash blower to properly resolve the slagging trouble.
