Application of biomass boiler and timber pellet gas<br>
Under the pressure of environmental protection and also power situation, numerous countries has carried out policies to cut exhaust and promote new power. Under this problem, more and more coal-fired boilers have been replaced by, or updated into biomass central heating boiler



Traditional coal-fired central heating boilers discharge a great deal of black smoke and also sulfur gas. Several of them are not geared up with desulfurizer. They will pollute the bordering locations. To change them with gas as well as electrical power requires too much initiatives and also cost, many coal-fired central heating boiler proprietor use biomass fuel to replace coal. Thinking about most coal-fired central heating boilers are unfit for biomass fuel, there are specific biomass fuel burning gadgets to solve this issue. They are developed based upon the characteristics of biomass gas as well as minimize the toxin emission.



Different types of biomass pellet central heating boiler

Biomass boiler adopts biomass energy, generally biomass pellets, as gas. According to various energy media, they can be categorized into biomass steam central heating boiler, biomass warm water central heating boiler, biomass hot blast stove, biomass thermal oil heating system.



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



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



Small biomass boiler

These central heating boilers utilizes strong or gasified biomass fuels They generate warm in the form of warm water. Little biomass boiler includes tiny volume, easy structure, small cost, yet it has reduced energy conversion efficiency as well as low power supply. Little biomass boiler is mostly for residence heating in backwoods and also hot water supply.



Massive biomass boiler.

These kind of biomass boiler use solid biomass fuel as well as provide hot water or vapor. The innovation is fully grown, the power supply is high, and the energy loss is low. However wood pellet press machine has gas cocking owing to inadequate burning, as well as the support center is not best.



Raw materials for biomass central heating boiler.

Biomass boiler has vast source of resources. All photosynthetic plants can be made use of as basic materials, consisting of sawdust, wood chips, rice husk, sunflower seed shell, sorghum stalk, corn stalk, bean stalk, and so on. By high-heat as well as high-pressure processing in the molding tools, these biomass products are formed right into columnar biomass fuel. They are fed into biomass boilers to produce heat.




2 typical biomass fuels.

Typically, biomass molding gas has 2 kinds-- biomass briquettes as well as wood pellet fuel. 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 slowly replace biomass briquettes owing to high density, vast application and hassle-free utilizing. They burns a lot more adequately than biomass briquettes.



Biomass pellet gas has fiber material of 70%. The sulfur web content is much less than coal High density makes it hassle-free to shop and transportation. It can be used in various tools. wood pellets fuel making machine burns completely, with much less smoke and also ash web content, as well as the combustion rate is 11% higher than coal.



Benefits of timber pellet gas over coal.

Low carbon content: biomass gas has at most 50% carbon web content, so the warm worth is less than coal.

High hydrogen content: biomass gas has even more volatiles, so they are easier to shed. The carbon and hydrogen are incorporated into reduced molecular hydrocarbon, which will certainly separate out volatiles at high temperature.

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

Reduced thickness: the thickness of biomass fuel is lower than coal. Loosen texture makes it less complicated to burn out. The recurring carbon is lower than coal ash.

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

Low carbon emission: biomass fuel is carbon-neutral, to put it simply, no carbon exhaust

Waste recycle: the fostering of biomass gas can make complete use wastes, and also alleviate their damage to setting. Besides, the residual ash after burning can be made use of to produce plant food.

Mixed firing: Biomass fuel can be melted together with coal and also improve the combustion effectiveness.



Biomass boiler contamination emission.

Biomass central heating boiler produce small quantity of air contaminants, and also strong waste that can be reused.



Contaminating gases

Biomass gas produces little NOx and no carbon dioxide. The SO2 discharge is lower than 33.6 mg/m3, as well as the smoke and ash emission is less than 46mg/m3. They are far lower than the national standard.



Strong waste

The primary 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 device, we can reduce the toxin discharge to minimum.



Ecological benefits of biomass central heating boiler

To replace coal with biomass gas, we can reduce the contaminant discharge in ambience. On the other hand, the internet carbon emission of biomass gas is absolutely no, which can eliminate greenhouse effect.



Fostering of biomass gas is a reliable means to make use of the crop waste. If these crop waste degeneration under natural problem, they will create a great deal of methane, which has greater pollution. By making them into fuel, we can transform waste into wealth.



The residual ash after shedding can be used as potash plant food. In this way, we attain the energy recycle among straw-- fuel-- fertilizer.
