Notes

Application of biomass boiler and also wood pellet gas<br>
Under the stress of environmental protection as well as power situation, lots of countries has actually performed plans to reduce discharge and promote brand-new power. Under this problem, an increasing number of coal-fired central heating boilers have actually been changed by, or updated into biomass central heating boiler



Traditional coal-fired central heating boilers discharge a lot of black smoke and sulfur gas. A few of them are not equipped with desulfurizer. They will contaminate the surrounding areas. To replace them with gas and power needs way too much efforts and also price, so many coal-fired boiler proprietor usage biomass gas to change coal. Thinking about most coal-fired central heating boilers are unfit for biomass fuel, there are specialized biomass fuel burning tools to resolve this issue. They are developed based upon the qualities of biomass gas as well as reduce the pollutant emission.



Various sorts of biomass pellet central heating boiler

Biomass central heating boiler takes on biomass power, typically biomass pellets, as fuel. According to various energy media, they can be identified right into biomass vapor boiler, biomass warm water boiler, biomass hot blast stove, biomass thermal oil heater.



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



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



Tiny biomass boiler

These central heating boilers makes use of strong or gasified biomass fuels They create warm in the form of hot water. Little biomass boiler features tiny quantity, simple framework, low price, but it has reduced energy conversion effectiveness and also reduced energy supply. Small biomass central heating boiler is mostly for home heating in backwoods as well as hot water supply.



Massive biomass central heating boiler.

These kind of biomass boiler use solid biomass gas and also provide warm water or heavy steam. The modern technology is mature, the power supply is high, and the energy loss is reduced. However some biomass central heating boiler has gas cocking owing to insufficient burning, and also the assistance center is not ideal.



Basic material for biomass boiler.

Biomass boiler has broad source of resources. All photosynthetic plants can be made use of as resources, consisting of sawdust, wood chips, rice husk, sunflower seed covering, sorghum stalk, corn stalk, bean stalk, etc. By high-heat and high-pressure handling in the molding equipment, these biomass materials are built right into columnar biomass fuel. They are fed right into biomass central heating boilers to generate heat.



Two usual biomass gas.

Normally, biomass molding fuel has 2 types-- biomass briquettes as well as wood pellet gas. The length of biomass briquettes is greater than 15cm, the diameter is 30-40mm. article source are made by biomass briquette press. Timber pellets is 6-8mm in size. They are made by wood pellet mill. Wood pellet gas slowly replace biomass briquettes owing to high density, broad application and convenient using. They burns extra completely than biomass briquettes.



Biomass pellet gas has fiber material of 70%. The sulfur web content is far lower than coal High density makes it convenient to shop and also transportation. It can be used in different equipment. Biomass pellets burns completely, with much less smoke and also ash content, and also the combustion rate is 11% higher than coal.




Advantages of timber pellet fuel over coal.

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

High hydrogen content: biomass fuels has even more volatiles, so they are less complicated to burn. additional resources and also hydrogen are combined right into reduced molecular hydrocarbon, which will certainly separate out volatiles at high temperature.

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

Low density: the thickness of biomass fuel is lower than coal. Loosen up texture makes it simpler to wear out. The residual carbon is lower than coal ash.

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

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

Waste recycle: the adoption of biomass gas can make complete use of wastes, and also soothe their damage to environment. Besides, the residual ash after melting can be made use of to produce plant food.

Combined shooting: Biomass gas can be melted together with coal as well as enhance the combustion performance.




Biomass boiler pollution exhaust.

Biomass central heating boiler release small quantity of air contaminants, as well as strong waste that can be reused.



Polluting gases

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



Strong waste

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



By furnishing the biomass boiler with desulfurizing and dirt removing device, we can reduce the contaminant exhaust to minimum.



Ecological benefits of biomass boiler

To replace coal with biomass fuel, we can reduce the pollutant discharge in ambience. On the other hand, the net carbon discharge of biomass fuel is zero, which can eliminate pollution.



Fostering of biomass fuel is an efficient method to take advantage of the crop waste. If Learn More Here under natural condition, they will produce a great deal of methane, which has higher greenhouse effect. By making them right into fuel, we can transform waste into wealth.



The recurring ash after melting can be made use of as potash plant food. In this way, we accomplish the power reuse among straw-- gas-- fertilizer.
