Application of biomass boiler and wood pellet fuel
Application of biomass central heating boiler as well as timber pellet gas
Under the pressure of environmental management and energy situation, several nations has actually performed plans to reduce emission and also promote new energy. Under this problem, a growing number of coal-fired boilers have actually been changed by, or updated into biomass boiler

Traditional coal-fired central heating boilers send out a lot of black smoke and also sulfur gas. Some of them are not equipped with desulfurizer. They will certainly pollute the surrounding locations. To change them with gas as well as electricity calls for excessive efforts and also expense, numerous coal-fired boiler owner usage biomass gas to change coal. Taking into consideration most coal-fired central heating boilers are unfit for biomass fuel, there are specific biomass gas burning devices to resolve this trouble. They are made based upon the qualities of biomass gas and decrease the contaminant discharge.

Various types of biomass pellet central heating boiler
Biomass boiler takes on biomass power, generally biomass pellets, as gas. According to different energy media, they can be identified right into biomass vapor boiler, biomass warm water boiler, biomass warm blast range, biomass thermal oil heating system.

According to their objective, biomass central heating boilers can be identified right into biomass thermal boiler and also biomass electrical power boiler They both produce power by melting biomass gas. Biomass thermal central heating boiler usage thermal power, while biomass electrical power central heating boiler turn the thermal energy right into electrical power. Biomass thermal central heating boiler is still the most preferred type, whose modern technology is mature.

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

Little biomass boiler
These boilers makes use of strong or gasified biomass fuels They create warmth in the form of warm water. Small biomass boiler features tiny volume, simple structure, small cost, but it has reduced energy conversion efficiency and reduced power supply. Little biomass central heating boiler is mostly for home heating in rural areas as well as warm water supply.

Large-scale biomass boiler.
These sort of biomass central heating boiler usage strong biomass fuel and also supply warm water or heavy steam. The innovation is mature, the power supply is high, and also the energy loss is low. But some biomass boiler has gas cocking owing to insufficient burning, and the assistance facility is not best.

Resources for biomass boiler.


Biomass boiler has large resource of raw materials. All photosynthetic plants can be utilized as basic materials, consisting of sawdust, wood chips, rice husk, sunflower seed shell, sorghum stalk, corn stalk, bean stalk, etc. By high-heat and high-pressure handling in the molding devices, these biomass materials are built into columnar biomass fuel. They are fed right into biomass boilers to generate heat.

2 usual biomass fuels.
Usually, biomass molding gas has 2 types-- biomass briquettes and wood pellet gas. The length of biomass briquettes is greater than 15cm, the size is 30-40mm. They are made by biomass briquette press. Timber pellets is 6-8mm in size. They are made by timber pellet mill. Wood pellet gas gradually fill in biomass briquettes owing to high density, wide application as well as hassle-free making use of. They burns more adequately than biomass briquettes.

Biomass pellet fuel has fiber content of 70%. The sulfur content is much lower than coal High thickness makes it convenient to shop and also transport. It can be used in different equipment. Biomass pellets burns sufficiently, with much less smoke as well as ash content, as well as the burning rate is 11% more than coal.

Advantages of wood pellet gas over coal.
Low carbon material: biomass gas has at most 50% carbon web content, so the heat value is lower than coal.
High hydrogen material: biomass fuels has more volatiles, so they are less complicated to burn. description and also hydrogen are combined into low molecular hydrocarbon, which will separate out volatiles at heat.
High oxygen content: biomass gas has even more oxygen web content than coal, so the warm worth is low.
fish feed pellet machine : the density of biomass gas is less than coal. Loosen up texture makes it simpler to wear out. The recurring carbon is lower than coal ash.
Reduced sulfur material: the sulfur content in biomass fuels are less than 0.12%. You do not require to mount desulfurizer gadget.
Reduced carbon discharge: biomass gas is carbon-neutral, simply put, zero carbon exhaust
Waste reuse: the fostering of biomass fuel can make complete use of wastes, and also alleviate their damage to atmosphere. Besides, the recurring ash after burning can be made use of to generate fertilizer.
Combined firing: Biomass gas can be burned together with coal as well as enhance the burning performance.

Biomass central heating boiler air pollution exhaust.
Biomass boiler give off small quantity of air pollutants, and solid waste that can be recycled.

Polluting gases
Biomass gas produces little NOx and no Co2. The SO2 exhaust is less than 33.6 mg/m3, and the smoke as well as ash exhaust is lower than 46mg/m3. They are much less than the nationwide standard.

Solid waste
The main solid waste of biomass central heating boiler is ash. They can be recycled by made right into potash plant food.

By gearing up the biomass central heating boiler with desulfurizing and also dust eliminating tool, we can minimize the contaminant emission to minimum.

Environmental benefits of biomass central heating boiler
To replace coal with biomass gas, we can lower the contaminant discharge in ambience. At the same time, the web carbon exhaust of biomass gas is no, which can soothe greenhouse effect.

Adoption of biomass gas is an effective means to utilize the plant waste. If these plant waste decay under natural condition, they will certainly create a lot of methane, which has higher pollution. By making them right into gas, we can turn waste right into riches.

The residual ash after melting can be utilized as potash fertilizer. This way, we accomplish the power reuse among straw-- fuel-- plant food.
