Technical parameters of biomass pellet fuel

The production of biomass pellet fuel requires a lot of equipment, which can not be solved by a machine, and the amount of equipment used depends on the situation of raw materials, as well as the requirements for the degree of automation and environmental protection. Let's talk about the full set of equipment in general. 1. Crushing equipment:

The large pieces of raw materials are processed into a few centimeters in size, and the common ones are all kinds of wood chip machines, tyrannosaurus crushers, etc., 2. Crushing equipment: crushing materials to below 15mm, common ones are high-efficiency crushers, multi-functional crushers. 3. Drying equipment:

The moisture of the material is dried to less than 15%, mainly the drum dryer. 4. Granulation equipment: the core equipment for pressing raw materials into granules, centrifugal high-efficiency granulator.

5. Cooling equipment: the particles are brought to room temperature, and the counter-flow cooler is generally used. 6. Other equipment:

Silo, conveying equipment 、...

The difference between biomass pellet fuel and wood is:

1. Biomass fuel pellets are made of corn straw, rice husk, cottonwood, peanut husk, peanut seedling, wood chips, bamboo chips and other crop straws as raw materials, which are pressed and molded by straw pellet machine into small particles for replacing coal combustion.

2. After processing, biomass pellet fuel has become hard and smooth in appearance, high calorific value, resistant to combustion, not easy to coke, and less polluting.

3. It can completely replace coal as a raw material for combustion.

4, and wood can be used as a raw material for biomass pellets to be processed and made into pellets, 5, if wood wants to be used as a raw material for production, it needs to be crushed by a crusher for processing and manufacturing, but it is necessary to consider the moisture of wood chips, if the moisture is too large, it will cause the particles to be not easy to form and cracks, affecting the quality and appearance.

Volume is their biggest difference, followed by raw materials, manufacturers may use pine, fungus residue and so on as raw materials, poplar, straw.

Summary. Hello, biomass pellet raw materials peanut shells, straw, sawdust, rice husks, corn stalks, tree bark, etc.

Biomass pellets are processed by cold dense molding of crushed biomass straw, forestry waste and other raw materials under normal temperature conditions by pressing rollers and ring dies.

What are the raw materials of biomass pellet fuel?

Hello, biomass pellet raw materials peanut shells, straw, sawdust, rice husks, corn stalks, tree bark, etc. Biomass pellets are processed by cold dense molding of crushed biomass straw, forestry waste and other raw materials under normal temperature conditions by pressing rollers and ring dies.

Are there any other raw materials added to it, and chemical anti-chemical raw materials?

Nope. Why can't I make it, there should be something added to it.

What is the process of making it?

It will gelatinize and burn poorly.

Calories can't be reached.

The presence of moisture and impurities in it will affect the effect.

Dear, I am glad to answer for you: the latest national standard for biomass burning pellets The EU standard does not put forward a specific value for the calorific value of biomass pellets, but requires the seller to mark it. The Swedish standard requires that the calorific value of biomass pellets should generally be in megajoules.

According to the classification standards of biomass pellets in Sweden and the European Union, if the intermediate classification value is taken as an example, biomass pellets can be roughly described as the following characteristics: the diameter of biomass pellets is generally 6 10 mm, the length is 4 5 times of its diameter, the crushing rate is less, the dry base moisture content is less than 15%, the ash content is less than 2%, the sulfur content and chlorine content are less, and the nitrogen bond content is less than that. Biomass fuel is produced by processing straw, straw, rice husk, peanut shell, corn cob, camellia husk, cottonseed husk, etc., as well as "three dismantling and brightening of the leftovers".

The diameter of the biomass pellets is generally 6 10 mm. 1. The calorific value of biomass pellet fuel is large, the calorific value is about 3900 4800 kcal kg, and the calorific value after carbonization is as high as 7000-8000 kcal Biomass pellet fuel has high purity, does not contain other impurities that do not produce heat, its carbon content is 75-85%, ash content is 3-6%, water content is 1-3%, and it absolutely does not contain coal gangue, stones and other impurities that do not heat up but consume heat, which will directly reduce costs for enterprises. 3. Biomass pellet fuel does not contain sulfur and phosphorus, does not corrode the boiler, can prolong the service life of the boiler, and enterprises will benefit a lot.

4. Because biomass pellet fuel does not contain sulfur and phosphorus, it does not produce sulfur dioxide and phosphorus pentoxide when burned, so it will not lead to acid rain, pollute the atmosphere and the environment. 5. Biomass pellet fuel is clean and hygienic, convenient to feed, reduces the labor intensity of workers, greatly improves the working environment, and the enterprise will reduce the cost of labor. 6. There is very little ash ballast after the combustion of biomass pellet fuel, which greatly reduces the site for stacking coal ballast and reduces the cost of ballast.

30 to 50% wood chips, 30 to 40% straw, 20 to 30% coal dust.

The present invention proposes a formula of biomass fuel pellets and its production process, various agricultural and forestry scraps are processed into biomass pellets through automatic production lines, the finished product has good drying effect, the finished product is of high quality, the anti-slag performance has been improved, the sulfur oxide emission of Erziliang has been greatly reduced, and as an environmentally friendly fuel combustion, the utilization of energy has been realized.

The advantages of biomass pellet fuel are as follows:

Clean and environmentally friendly, biomass pellet fuel is a kind of pure natural, no chemical addition of biomass pellet fuel, can replace coal-fired fuel and other highly polluting fuels, with environmental protection, high combustion value, high combustion rate and other characteristics.

Biomass pellets have good environmental benefits. The application of coal and kerosene, not only to invest in expensive desulfurization and denitrification equipment, but also to pay expensive desulfurization and denitrification costs for project operation, biomass fuel sulfur, nitrogen, ash content is very low, in line with the clean fuel index, no need to take desulfurization, denitrification measures can meet the national environmental protection requirements when combusting, which is not only an environmentally friendly fuel, but also reduces the cost of environmental protection investment. As a result, cleaner production has been achieved in both production processing and production applications.
