Application of biomass boiler and also wood pellet gas<br>
Under the pressure of environmental protection and also power situation, several nations has executed policies to reduce exhaust and promote new power. Under this condition, increasingly more coal-fired boilers have actually been changed by, or upgraded into biomass boiler



Conventional coal-fired central heating boilers release a great deal of black smoke and sulfur gas. A few of them are not furnished with desulfurizer. granulator pellet will certainly pollute the surrounding locations. To change them with gas as well as electrical power calls for way too much efforts as well as price, so many coal-fired boiler owner use biomass fuel to change coal. Considering most coal-fired boilers are unfit for biomass fuel, there are customized biomass gas burning tools to fix this issue. They are designed based on the qualities of biomass gas as well as decrease the contaminant emission.



Different sorts of biomass pellet boiler

Biomass boiler adopts biomass energy, generally biomass pellets, as gas. According to various energy media, they can be classified right into biomass heavy steam central heating boiler, biomass warm water boiler, biomass hot blast stove, biomass thermal oil heater.




According to their purpose, biomass boilers can be categorized into biomass thermal boiler and also biomass electric power boiler They both create power by shedding biomass fuels. Biomass thermal boiler use thermal energy, while biomass electrical power central heating boiler turn the thermal power into electrical power. Biomass thermal boiler is still one of the most prominent kind, whose modern technology is fully grown.



According to the scale, biomass thermal boiler can be classified right into 2 types.



Small biomass central heating boiler

These central heating boilers utilizes solid or gasified biomass gas They generate warm in the form of warm water. Little biomass boiler includes tiny volume, simple framework, low price, yet it has reduced energy conversion effectiveness as well as reduced energy supply. Small biomass boiler is generally for home heating in backwoods as well as warm water supply.



Large-scale biomass central heating boiler.

These type of biomass central heating boiler use solid biomass gas and supply warm water or steam. The technology is mature, the energy supply is high, and also the power loss is reduced. But some biomass boiler has gas cocking owing to not enough burning, and the assistance facility is not ideal.



Raw materials for biomass boiler.

Biomass boiler has wide resource of resources. All photosynthetic plants can be utilized as resources, including sawdust, wood chips, rice husk, sunflower seed covering, sorghum stalk, corn stalk, bean stalk, etc. By high-heat as well as high-pressure handling in the molding equipment, these biomass products are molded right into columnar biomass gas. They are fed right into biomass central heating boilers to produce warmth.



2 typical biomass fuels.

Usually, biomass molding gas has 2 kinds-- biomass briquettes as well as timber pellet fuel. The size of biomass briquettes is greater than 15cm, the diameter is 30-40mm. They are made by biomass briquette press. Wood pellets is 6-8mm in diameter. They are made by wood pellet mill. Timber pellet gas progressively fill in biomass briquettes owing to high thickness, vast application and hassle-free using. They burns more adequately than biomass briquettes.



Biomass pellet fuel has fiber content of 70%. The sulfur content is far lower than coal High thickness makes it practical to store as well as transport. It can be used in different devices. Biomass pellets burns sufficiently, with less smoke and also ash content, and also the combustion rate is 11% greater than coal.



Advantages of wood pellet gas over coal.

Low carbon content: biomass gas has at many 50% carbon content, so the heat value is lower than coal.

High hydrogen content: biomass fuels has even more volatiles, so they are simpler to shed. chicken feed making machine for sale as well as hydrogen are combined right into low molecular hydrocarbon, which will certainly separate out volatiles at heat.

High oxygen web content: biomass gas has more oxygen content than coal, so the warmth value is reduced.

Reduced density: the density of biomass gas is less than coal. Loosen up texture makes it easier to wear out. The residual carbon is less than coal ash.

Reduced sulfur material: the sulfur material in biomass gas are less than 0.12%. You don't require to mount desulfurizer gadget.

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

Waste recycle: the adoption of biomass gas can make complete use wastes, and ease their damage to atmosphere. Besides, the recurring ash after melting can be made use of to create plant food.

Blended firing: Biomass fuel can be burned together with coal and enhance the burning effectiveness.



Biomass boiler air pollution discharge.


Biomass central heating boiler release small quantity of air pollutants, as well as strong waste that can be recycled.



Contaminating gases

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



Strong waste

The main solid waste of biomass central heating boiler is ash. They can be reused by made into potash fertilizer.



By furnishing the biomass central heating boiler with desulfurizing as well as dust removing tool, we can decrease the pollutant emission to minimum.



Ecological benefits of biomass boiler

To change coal with biomass gas, we can reduce the toxin discharge in atmosphere. On the other hand, the net carbon exhaust of biomass fuel is no, which can relieve greenhouse effect.



Fostering of biomass gas is an efficient method to utilize the plant waste. If these crop waste degeneration under natural problem, they will generate a lot of methane, which has higher greenhouse effect. By making richi machinery into fuel, we can turn waste into wide range.



The recurring ash after burning can be used as potash plant food. In this way, we achieve the energy recycle among straw-- fuel-- plant food.
