Application of biomass boiler as well as timber pellet gas<br>
Under the pressure of environmental protection and power dilemma, numerous nations has actually accomplished policies to reduce exhaust as well as promote brand-new energy. Under this condition, a growing number of coal-fired central heating boilers have been replaced by, or upgraded into biomass boiler



Traditional coal-fired boilers send out a great deal of black smoke and sulfur gas. Some of them are not geared up with desulfurizer. They will certainly pollute the bordering locations. To replace them with gas and also power requires way too much initiatives and expense, so many coal-fired boiler owner use biomass gas to change coal. Thinking about most coal-fired boilers are unsuited for biomass gas, there are specific biomass fuel burning tools to fix this trouble. They are made based upon the qualities of biomass fuel as well as decrease the contaminant emission.



Various sorts of biomass pellet boiler

Biomass central heating boiler takes on biomass energy, typically biomass pellets, as fuel. According to small feed pellet machine , they can be classified right into biomass heavy steam boiler, biomass hot water central heating boiler, biomass warm blast range, biomass thermal oil heating system.



According to their objective, biomass boilers can be categorized right into biomass thermal central heating boiler as well as biomass electric power central heating boiler They both create power by burning biomass fuels. Biomass thermal central heating boiler usage thermal energy, while biomass electric power boiler turn the thermal power right into electric power. Biomass thermal boiler is still one of the most prominent type, whose technology is fully grown.



According to the range, biomass thermal boiler can be classified right into 2 kinds.



Little biomass central heating boiler

These central heating boilers utilizes solid or gasified biomass fuels They create heat in the form of hot water. matador pellet mill includes tiny quantity, easy framework, low cost, however it has reduced power conversion performance as well as low power supply. Little biomass boiler is mainly for home heating in backwoods and also warm water supply.



Large biomass boiler.

These type of biomass central heating boiler usage strong biomass fuel and provide warm water or vapor. The innovation is mature, the energy supply is high, and the energy loss is low. But chicken feed machine price has fuel cocking owing to inadequate burning, as well as the assistance center is not perfect.



Basic material for biomass central heating boiler.

Biomass central heating boiler has large source of resources. All photosynthetic plants can be used as basic materials, including sawdust, wood chips, rice husk, sunflower seed covering, sorghum stalk, corn stalk, bean stalk, and so on. By high-heat as well as high-pressure processing in the molding tools, these biomass materials are molded right into columnar biomass fuel. They are fed into biomass central heating boilers to create heat.



Two common biomass fuels.

Usually, biomass molding gas has 2 kinds-- biomass briquettes and also timber pellet gas. The size of biomass briquettes is greater than 15cm, the diameter is 30-40mm. They are made by biomass briquette press. Timber pellets is 6-8mm in diameter. They are made by timber pellet mill. Timber pellet fuels progressively fill in biomass briquettes owing to high density, wide application and also hassle-free utilizing. They burns extra completely than biomass briquettes.



Biomass pellet gas has fiber web content of 70%. The sulfur content is much lower than coal High thickness makes it hassle-free to store as well as transportation. It can be applied in different equipment. Biomass pellets burns adequately, with much less smoke and ash web content, as well as the burning speed is 11% higher than coal.



Advantages of timber pellet fuel over coal.


Low carbon material: biomass fuels has at many 50% carbon web content, so the heat worth is less than coal.

High hydrogen material: biomass fuels has even more volatiles, so they are easier to burn. The carbon and hydrogen are integrated right into low molecular hydrocarbon, which will separate out volatiles at heat.

High oxygen content: biomass gas has even more oxygen content than coal, so the heat worth is reduced.

Reduced density: the thickness of biomass fuel is lower than coal. Loosen appearance makes it less complicated to wear out. The recurring carbon is less than coal ash.

Low sulfur content: the sulfur web content in biomass gas are less than 0.12%. You do not require to set up desulfurizer tool.

Low carbon exhaust: biomass fuel is carbon-neutral, to put it simply, zero carbon emission

Waste recycle: the adoption of biomass fuel can make full use wastes, and eliminate their damages to atmosphere. Besides, the residual ash after burning can be made use of to produce plant food.

Blended firing: Biomass gas can be shed together with coal and enhance the burning performance.



Biomass central heating boiler pollution emission.

Biomass central heating boiler emit small quantity of air contaminants, and solid waste that can be recycled.



Polluting gases

Biomass gas creates little NOx and also no Co2. The SO2 emission is lower than 33.6 mg/m3, as well as the smoke and ash exhaust is lower than 46mg/m3. They are much less than the national requirement.



Solid waste

The major strong waste of biomass boiler is ash. They can be reused by made into potash plant food.



By gearing up the biomass boiler with desulfurizing as well as dirt eliminating tool, we can lower the pollutant emission to minimum.



Environmental advantages of biomass central heating boiler

To replace coal with biomass gas, we can reduce the toxin emission in atmosphere. Meanwhile, the internet carbon emission of biomass gas is absolutely no, which can eliminate greenhouse effect.



Adoption of biomass gas is an efficient means to take advantage of the plant waste. If these crop waste degeneration under all-natural problem, they will certainly generate a great deal of methane, which has higher pollution. By making them right into gas, we can turn waste right into riches.




The recurring ash after shedding can be made use of as potash fertilizer. This way, we accomplish the power recycle amongst straw-- gas-- fertilizer.
