Application of biomass boiler and wood pellet fuel
biomass pellet plant of biomass central heating boiler and wood pellet gas
Under the pressure of environmental protection as well as power dilemma, numerous nations has actually performed policies to reduce exhaust and also promote new energy. Under this condition, more and more coal-fired boilers have been replaced by, or upgraded right into biomass boiler

Typical coal-fired central heating boilers give off a great deal of black smoke and sulfur gas. A few of them are not furnished with desulfurizer. pet food pellet machine will contaminate the surrounding areas. To replace them with gas and also electricity needs way too much initiatives and also expense, many coal-fired central heating boiler owner use biomass gas to replace coal. Thinking about most coal-fired boilers are unfit for biomass gas, there are specialized biomass gas burning devices to address this problem. They are made based on the attributes of biomass gas as well as minimize the toxin emission.

Different kinds of biomass pellet central heating boiler
Biomass boiler takes on biomass power, generally biomass pellets, as gas. According to different power media, they can be categorized right into biomass heavy steam central heating boiler, biomass hot water central heating boiler, biomass hot blast cooktop, biomass thermal oil heating system.

According to their purpose, biomass central heating boilers can be classified into biomass thermal boiler and also biomass electric power boiler They both create power by burning biomass fuels. Biomass thermal central heating boiler use thermal power, while biomass electrical power boiler transform the thermal energy into electric power. Biomass thermal boiler is still the most preferred kind, whose technology is fully grown.

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

Little biomass boiler
These boilers makes use of solid or gasified biomass fuels They produce heat in the form of warm water. Tiny biomass central heating boiler includes small quantity, straightforward structure, small cost, but it has reduced power conversion effectiveness and reduced power supply. Small biomass boiler is primarily for residence heating in rural areas as well as warm water supply.

Large biomass central heating boiler.
These kind of biomass central heating boiler usage solid biomass gas as well as provide hot water or heavy steam. The modern technology is fully grown, the energy supply is high, and the energy loss is reduced. However some biomass central heating boiler has fuel cocking owing to insufficient burning, and also the support facility is not best.


Raw materials for biomass central heating boiler.
Biomass boiler has wide resource of resources. All photosynthetic plants can be used as basic materials, consisting of sawdust, wood chips, rice husk, sunflower seed shell, sorghum stalk, corn stalk, bean stalk, etc. By high-heat and also high-pressure processing in the molding tools, these biomass products are formed into columnar biomass gas. They are fed into biomass boilers to generate warm.

2 common biomass fuels.
Generally, biomass molding fuel has 2 kinds-- biomass briquettes and also timber pellet gas. The size of biomass briquettes is more than 15cm, the diameter is 30-40mm. They are made by biomass briquette press. Wood pellets is 6-8mm in size. They are made by wood pellet mill. Timber pellet fuels gradually fill in biomass briquettes owing to high density, broad application and also hassle-free utilizing. They burns much more adequately than biomass briquettes.

Biomass pellet gas has fiber web content of 70%. The sulfur web content is much lower than coal High density makes it convenient to shop as well as transport. It can be used in various equipment. Biomass pellets burns sufficiently, with much less smoke and ash material, and also the combustion rate is 11% greater than coal.

Advantages of wood pellet fuel over coal.
Low carbon content: biomass fuels contends many 50% carbon material, so the warmth worth is less than coal.
High hydrogen material: biomass gas has more volatiles, so they are less complicated to burn. The carbon and hydrogen are incorporated right into reduced molecular hydrocarbon, which will separate out volatiles at heat.
High oxygen material: biomass gas has more oxygen material than coal, so the warmth value is low.
Low density: the thickness of biomass fuel is lower than coal. Loosen up structure makes it easier to wear out. The recurring carbon is lower than coal ash.
Reduced sulfur web content: the sulfur content in biomass fuels are less than 0.12%. You do not require to mount desulfurizer gadget.
Reduced carbon emission: biomass gas is carbon-neutral, simply put, absolutely no carbon discharge
Waste reuse: the fostering of biomass fuel can make complete use wastes, as well as ease their damages to setting. Besides, the recurring ash after shedding can be made use of to produce fertilizer.
Mixed firing: Biomass gas can be burned along with coal as well as enhance the combustion effectiveness.

Biomass boiler pollution emission.
Biomass central heating boiler release small quantity of air toxins, and solid waste that can be recycled.

Contaminating gases
Biomass gas creates little NOx and no Co2. The SO2 discharge is less than 33.6 mg/m3, and the smoke and also ash exhaust is lower than 46mg/m3. They are far less than the nationwide standard.

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

By outfitting the biomass boiler with desulfurizing as well as dirt removing tool, we can lower the toxin exhaust to minimum.

Ecological advantages of biomass central heating boiler
To change coal with biomass fuel, we can decrease the contaminant discharge in environment. On the other hand, the web carbon discharge of biomass gas is no, which can eliminate greenhouse effect.

Adoption of biomass gas is an efficient method to make use of the plant waste. If these crop waste decay under natural condition, they will create a great deal of methane, which has higher pollution. By making them into fuel, we can turn waste right into wealth.

The residual ash after burning can be used as potash fertilizer. This way, we achieve the power reuse amongst straw-- gas-- fertilizer.
