Application of biomass boiler and also wood pellet fuel<br>
Under the pressure of environmental protection and energy dilemma, numerous countries has actually carried out policies to reduce exhaust as well as promote brand-new energy. Under this problem, an increasing number of coal-fired central heating boilers have been changed by, or upgraded into biomass boiler



Typical coal-fired central heating boilers produce a great deal of black smoke and sulfur gas. A few of them are not outfitted with desulfurizer. They will certainly contaminate the bordering locations. To change them with gas and power needs too much efforts and also expense, numerous coal-fired central heating boiler owner use biomass fuel to change coal. Taking into consideration most coal-fired boilers are unsuited for biomass fuel, there are specific biomass fuel burning gadgets to address this trouble. They are developed based on the attributes of biomass gas and reduce the toxin exhaust.




Different kinds of biomass pellet central heating boiler

Biomass central heating boiler takes on biomass power, typically biomass pellets, as fuel. According to different energy media, they can be classified into biomass steam central heating boiler, biomass warm water central heating boiler, biomass hot blast stove, biomass thermal oil heating system.



According to their purpose, biomass central heating boilers can be identified into biomass thermal boiler and biomass electrical power central heating boiler They both produce power by burning biomass gas. Biomass thermal central heating boiler use thermal power, while biomass electric power central heating boiler turn the thermal power into electrical power. Biomass thermal central heating boiler is still the most popular type, whose innovation is fully grown.




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



Small biomass central heating boiler

These boilers makes use of strong or gasified biomass fuels They create heat in the form of hot water. gemco wood pellet machine includes tiny volume, simple structure, affordable price, yet it has reduced energy conversion efficiency and low power supply. Tiny biomass central heating boiler is generally for house heating in rural areas as well as hot water supply.



Massive biomass boiler.

These type of biomass boiler use strong biomass fuel as well as offer warm water or steam. The innovation is mature, the power supply is high, as well as the energy loss is low. But some biomass boiler has gas cocking owing to not enough burning, and the support facility is not best.



Basic material for biomass central heating boiler.

Biomass central heating boiler has wide resource of basic materials. All photosynthetic plants can be utilized as resources, including sawdust, timber chips, rice husk, sunflower seed shell, sorghum stalk, corn stalk, bean stalk, and so on. By high-heat and high-pressure handling in the molding devices, these biomass products are molded into columnar biomass gas. They are fed right into biomass boilers to produce warm.



Two common biomass gas.

Generally, biomass molding fuel has 2 types-- biomass briquettes and wood pellet gas. The size of biomass briquettes is more than 15cm, the size is 30-40mm. They are made by biomass briquette press. Timber pellets is 6-8mm in diameter. They are made by wood pellet mill. Wood pellet gas progressively fill in biomass briquettes owing to high density, broad application and practical utilizing. They burns a lot more sufficiently than biomass briquettes.



Biomass pellet gas has fiber web content of 70%. richi pellet machine is much lower than coal High density makes it convenient to shop and also transportation. It can be applied in different devices. Biomass pellets burns sufficiently, with less smoke and ash material, as well as the burning rate is 11% higher than coal.



Advantages of wood pellet fuel over coal.

Reduced carbon content: biomass fuels has at the majority of 50% carbon content, so the warm value is less than coal.

High hydrogen web content: biomass fuels has more volatiles, so they are simpler to burn. The carbon and also hydrogen are incorporated right into low molecular hydrocarbon, which will certainly separate out volatiles at high temperature.

High oxygen content: biomass gas has more oxygen content than coal, so the warm worth is low.

Low thickness: the thickness of biomass gas is less than coal. Loosen texture makes it much easier to burn out. The residual carbon is lower than coal ash.

Reduced sulfur material: the sulfur content in biomass gas are less than 0.12%. You do not need to set up desulfurizer gadget.

Reduced carbon exhaust: biomass gas is carbon-neutral, in other words, no carbon exhaust

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

Mixed shooting: Biomass fuel can be burned together with coal and also boost the combustion effectiveness.



Biomass central heating boiler pollution emission.

Biomass boiler release small quantity of air contaminants, and strong waste that can be reused.



Contaminating gases

Biomass fuel creates little NOx and also no carbon dioxide. The SO2 emission is lower than 33.6 mg/m3, and also the smoke as well as ash discharge is lower than 46mg/m3. They are far lower than the nationwide requirement.



Solid waste

The major solid waste of biomass boiler is ash. They can be reused by made right into potash fertilizer.



By equipping the biomass boiler with desulfurizing and dirt eliminating gadget, we can minimize the toxin emission to minimum.



Ecological advantages of biomass central heating boiler

To change coal with biomass fuel, we can reduce the contaminant exhaust in environment. Meanwhile, the web carbon exhaust of biomass fuel is zero, which can relieve pollution.



Fostering of biomass gas is a reliable means to take advantage of the crop waste. If these plant waste decay under natural condition, they will certainly create a great deal of methane, which has higher pollution. By making them right into fuel, we can transform waste right into riches.



The recurring ash after burning can be utilized as potash plant food. In this way, we accomplish the power reuse among straw-- gas-- plant food.
