Application of biomass central heating boiler and also wood pellet fuel<br>
Under the pressure of environmental protection and power dilemma, lots of nations has carried out plans to cut exhaust and also promote brand-new energy. Under this problem, an increasing number of coal-fired boilers have actually been replaced by, or updated into biomass central heating boiler



Conventional coal-fired boilers emit a great deal of black smoke and also sulfur gas. Several of them are not furnished with desulfurizer. They will contaminate the bordering locations. To replace them with gas and electricity calls for excessive initiatives and cost, numerous coal-fired boiler proprietor use biomass fuel to change coal. Taking into consideration most coal-fired central heating boilers are unsuited for biomass gas, there are specific biomass fuel burning tools to solve this issue. They are developed based on the characteristics of biomass gas and decrease the pollutant exhaust.



Different types of biomass pellet boiler

Biomass boiler adopts biomass power, usually biomass pellets, as fuel. According to various energy media, they can be classified right into biomass heavy steam boiler, biomass hot water boiler, biomass warm blast cooktop, biomass thermal oil heating system.



According to their objective, biomass central heating boilers can be categorized into biomass thermal central heating boiler and biomass electrical power boiler They both create power by burning biomass gas. Biomass thermal central heating boiler usage thermal power, while biomass electrical power central heating boiler transform the thermal energy right into electric power. Biomass thermal boiler is still one of the most popular type, whose modern technology is fully grown.



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



Tiny biomass central heating boiler

These central heating boilers uses strong or gasified biomass gas They create warm in the form of warm water. Tiny biomass boiler features small quantity, basic framework, affordable price, yet it has low power conversion efficiency as well as reduced power supply. Little biomass central heating boiler is primarily for house heating in backwoods as well as hot water supply.



Massive biomass central heating boiler.

These kind of biomass boiler use strong biomass gas as well as give hot water or heavy steam. The modern technology is mature, the power supply is high, and also the power loss is reduced. Yet some biomass central heating boiler has fuel cocking owing to inadequate burning, as well as the assistance center is not perfect.



Basic material for biomass boiler.

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



2 typical biomass gas.

Usually, biomass molding gas has 2 types-- biomass briquettes and also wood pellet fuel. The size of biomass briquettes is greater than 15cm, the diameter is 30-40mm. They are made by biomass briquette press. Timber pellets is 6-8mm in size. They are made by timber pellet mill. Timber pellet gas gradually replace biomass briquettes owing to high density, wide application and practical making use of. They burns a lot more sufficiently than biomass briquettes.



Biomass pellet gas has fiber web content of 70%. The sulfur content is far lower than coal High density makes it convenient to store as well as transport. It can be applied in different tools. paper pellet maker burns completely, with much less smoke and ash web content, and also the burning rate is 11% greater than coal.



Advantages of wood pellet gas over coal.


Low carbon material: biomass gas contends many 50% carbon material, so the warmth value is less than coal.

High hydrogen web content: biomass gas has more volatiles, so they are much easier to shed. The carbon and hydrogen are integrated into reduced molecular hydrocarbon, which will separate out volatiles at heat.

High oxygen material: biomass fuel has more oxygen content than coal, so the warmth worth is low.

Reduced thickness: the thickness of biomass fuel is less than coal. Loosen structure makes it simpler to stress out. machine for making chicken feed is lower than coal ash.

Low sulfur material: the sulfur material in biomass gas are less than 0.12%. You do not require to mount desulfurizer device.

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

Waste recycle: the fostering of biomass fuel can make full use of wastes, as well as relieve their damages to setting. Besides, the residual ash after shedding can be utilized to produce fertilizer.

Mixed shooting: Biomass gas can be burned along with coal as well as enhance the combustion efficiency.



Biomass boiler pollution exhaust.

Biomass boiler discharge small quantity of air toxins, and strong waste that can be reused.




Contaminating gases

Biomass gas generates little NOx as well as no carbon dioxide. The SO2 discharge is less than 33.6 mg/m3, and also the smoke as well as ash emission is less than 46mg/m3. They are much less than the national criterion.



Strong waste

The primary 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 getting rid of gadget, we can decrease the toxin emission to minimum.



Ecological advantages of biomass central heating boiler

To replace coal with biomass gas, we can lower the contaminant discharge in ambience. On the other hand, the net carbon emission of biomass fuel is absolutely no, which can relieve greenhouse effect.



Fostering of biomass gas is a reliable means to use the plant waste. If these plant waste degeneration under natural problem, they will produce a lot of methane, which has higher greenhouse effect. By making them into gas, we can transform waste into wealth.



The recurring ash after melting can be made use of as potash plant food. This way, we achieve the power recycle amongst straw-- fuel-- fertilizer.
