Application of biomass central heating boiler and also timber pellet gas<br>
Under the pressure of environmental management and energy dilemma, lots of countries has performed plans to cut discharge and advertise new energy. Under this condition, more and more coal-fired boilers have actually been changed by, or upgraded into biomass central heating boiler



Traditional coal-fired central heating boilers release a lot of black smoke and sulfur gas. Several of them are not geared up with desulfurizer. They will contaminate the bordering locations. To replace them with gas and also power needs excessive efforts and expense, many coal-fired boiler owner use biomass gas to change coal. Thinking about most coal-fired central heating boilers are unfit for biomass gas, there are specialized biomass fuel burning gadgets to fix this issue. They are designed based upon the features of biomass gas and also minimize the pollutant emission.



Various sorts of biomass pellet central heating boiler


Biomass central heating boiler embraces biomass energy, usually biomass pellets, as gas. According to various power media, they can be categorized into biomass vapor boiler, biomass warm water boiler, biomass warm blast range, biomass thermal oil heater.



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



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



Small biomass boiler

These boilers makes use of strong or gasified biomass gas They produce warmth in the form of hot water. Tiny biomass central heating boiler features little quantity, straightforward framework, low price, but it has low energy conversion effectiveness and also reduced energy supply. Little biomass central heating boiler is mainly for house heating in rural areas and also hot water supply.



Large biomass boiler.

These type of biomass boiler use strong biomass gas and also offer hot water or steam. The innovation is fully grown, the energy supply is high, and the power loss is reduced. But some biomass boiler has fuel cocking owing to insufficient burning, as well as the assistance facility is not excellent.



Basic material for biomass boiler.

Biomass boiler has wide resource of basic materials. All photosynthetic plants can be used as basic materials, including sawdust, wood chips, rice husk, sunflower seed covering, sorghum stalk, corn stalk, bean stalk, and so on. By high-heat as well as high-pressure handling in the molding equipment, these biomass materials are molded right into columnar biomass gas. They are fed into biomass boilers to produce warmth.



2 typical biomass fuels.

Normally, biomass molding gas has 2 kinds-- biomass briquettes as well as wood pellet gas. The size of biomass briquettes is greater than 15cm, the size is 30-40mm. They are made by biomass briquette press. Wood pellets is 6-8mm in diameter. They are made by timber pellet mill. poultry feed pellet machine price fuels gradually fill in biomass briquettes owing to high density, large application and also practical using. They burns extra sufficiently than biomass briquettes.



Biomass pellet gas has fiber material of 70%. The sulfur web content is far lower than coal High thickness makes it convenient to store as well as transport. It can be applied in different tools. Biomass pellets burns adequately, with much less smoke as well as ash content, and the burning speed is 11% higher than coal.



Advantages of timber pellet gas over coal.

Low carbon material: biomass fuels contends a lot of 50% carbon content, so the heat value is lower than coal.

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

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

Reduced density: the density of biomass fuel is less than coal. Loosen up texture makes it easier to stress out. wood pelletizer equipment is lower than coal ash.

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

Reduced carbon emission: biomass gas is carbon-neutral, simply put, zero carbon emission

Waste recycle: the fostering of biomass fuel can make full use of wastes, as well as alleviate their damage to setting. Besides, the recurring ash after burning can be made use of to generate plant food.

Blended shooting: Biomass gas can be shed along with coal and boost the combustion efficiency.



Biomass central heating boiler pollution emission.

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




Polluting gases

Biomass gas produces little NOx as well as no Co2. The SO2 discharge is less than 33.6 mg/m3, as well as the smoke and ash discharge is lower than 46mg/m3. They are much lower than the nationwide requirement.



Strong waste

The primary solid waste of biomass boiler is ash. They can be recycled by made into potash plant food.



By furnishing the biomass central heating boiler with desulfurizing and also dirt getting rid of device, we can minimize the contaminant emission to minimum.



Environmental benefits of biomass boiler

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



Fostering of biomass fuel is a reliable way to utilize the plant waste. If these plant waste decay under natural condition, they will produce a lot of methane, which has greater pollution. By making them right into fuel, we can transform waste into riches.



The residual ash after shedding can be made use of as potash fertilizer. In this way, we attain the power recycle amongst straw-- gas-- fertilizer.
