Application of biomass central heating boiler and also timber pellet fuel<br>
Under the stress of environmental management and power situation, several nations has carried out plans to reduce discharge as well as promote brand-new energy. Under this condition, a growing number of coal-fired central heating boilers have actually been changed by, or updated into biomass central heating boiler



Conventional coal-fired boilers produce a lot of black smoke as well as sulfur gas. Some of them are not furnished with desulfurizer. They will contaminate the bordering areas. To replace them with gas and electrical energy requires too much efforts and also price, so many coal-fired boiler owner use biomass fuel to replace coal. Considering most coal-fired central heating boilers are unsuited for biomass gas, there are specialized biomass gas burning devices to solve this trouble. They are created based upon the attributes of biomass gas and also decrease the toxin emission.



Various sorts of biomass pellet central heating boiler

Biomass central heating boiler embraces biomass energy, usually biomass pellets, as gas. According to various energy media, they can be identified into biomass steam boiler, biomass hot water boiler, biomass hot blast oven, biomass thermal oil heating system.



According to their function, biomass central heating boilers can be categorized into biomass thermal boiler and biomass electric power central heating boiler They both produce power by shedding biomass fuels. Biomass thermal boiler use thermal energy, while biomass electric power central heating boiler turn the thermal power right into electric power. Biomass thermal boiler is still one of the most popular kind, whose technology is fully grown.



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



Small biomass central heating boiler

These central heating boilers makes use of strong or gasified biomass gas They generate warmth in the form of warm water. Tiny biomass central heating boiler features tiny quantity, easy framework, affordable price, however it has reduced power conversion effectiveness and also reduced power supply. Little biomass boiler is mostly for home heating in backwoods and hot water supply.



Large-scale biomass boiler.

These type of biomass central heating boiler usage solid biomass gas and offer warm water or vapor. The modern technology is mature, the energy supply is high, and also the power loss is reduced. However some biomass central heating boiler has gas cocking owing to not enough burning, and the support facility is not excellent.



Raw materials for biomass central heating boiler.

Biomass central heating boiler has large source of basic materials. All photosynthetic plants can be made use of as resources, consisting of sawdust, timber 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 devices, these biomass products are formed into columnar biomass fuel. They are fed right into biomass boilers to produce heat.



2 common biomass fuels.

Normally, biomass molding gas has 2 kinds-- biomass briquettes and also wood pellet gas. The length of biomass briquettes is more than 15cm, the size is 30-40mm. They are made by biomass briquette press. Wood pellets is 6-8mm in size. They are made by timber pellet mill. Wood pellet fuels progressively replace biomass briquettes owing to high thickness, broad application and hassle-free utilizing. They burns a lot more sufficiently than biomass briquettes.



Biomass pellet fuel has fiber material of 70%. The sulfur material is far lower than coal High density makes it practical to store and also transportation. It can be used in different equipment. richi pellet machine burns adequately, with less smoke and ash content, as well as the burning speed is 11% greater than coal.



Advantages of timber pellet fuel over coal.

Reduced carbon web content: biomass fuels has at a lot of 50% carbon content, so the warm value is lower than coal.

High hydrogen content: biomass fuels has even more volatiles, so they are much easier to shed. The carbon as well as hydrogen are integrated into reduced molecular hydrocarbon, which will certainly separate out volatiles at heat.

High oxygen web content: biomass fuel has more oxygen content than coal, so the warm value is low.

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


Reduced sulfur web content: the sulfur content in biomass fuels are less than 0.12%. You do not require to set up desulfurizer gadget.

Reduced carbon exhaust: biomass gas is carbon-neutral, simply put, no carbon discharge

Waste reuse: the adoption of biomass fuel can make full use wastes, and also relieve their damages to setting. Besides, the recurring ash after burning can be utilized to produce plant food.

Combined shooting: Biomass fuel can be burned together with coal as well as enhance the combustion effectiveness.



Biomass boiler contamination exhaust.

Biomass boiler send out small quantity of air pollutants, and solid waste that can be recycled.



Contaminating gases

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



Solid waste

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



By furnishing the biomass central heating boiler with desulfurizing as well as dirt eliminating gadget, we can minimize the contaminant discharge to minimum.



Ecological advantages of biomass boiler

To replace coal with biomass fuel, we can lower the contaminant emission in ambience. At the same time, the web carbon exhaust of biomass gas is zero, which can alleviate pollution.




Fostering of biomass gas is an efficient way to utilize the plant waste. If these plant waste degeneration under natural problem, they will create a great deal of methane, which has higher pollution. By making small poultry feed making machine into gas, we can transform waste into riches.



The recurring ash after melting can be used as potash plant food. In this way, we achieve the energy reuse amongst straw-- fuel-- fertilizer.
