The pellet fuel raw materials produced by the wood pellet machine are mainly agricultural and forestry wastes, including straw, sawdust, wood chips, straw, etc., which are extruded into rod-shaped pellet fuel by pressure. So what are the advantages of pellet fuel compared with coal? Compared with coal, the pellet fuel produced by the wood pellet machine has many advantages. The specific analysis is as follows:

  1. The price of biomass pellet fuel is much lower than that of coal. At present, the price of coal in the market is 20-30 US dollars per ton higher than the price of biomass pellet fuel.

  2. Pellet fuel is a new type of biomass energy and is more environmentally friendly.

  3. Biomass pellet fuel has uniform shape, small volume and high density, which is convenient for transportation and storage.

  4. Biomass pellet fuel can be fully combusted. Sometimes coal cannot be fully combusted when the purity is not high, and there will be coal impurities. The burning rate of pellet fuel matches the rate of decomposition. Take straw as an example. After the straw is compressed into pellet fuel by the wood pellet machine, the combustion efficiency is increased from 20% to more than 80%; the heat of straw pellet combustion is 4500 kcal/kg, the average sulfur content is only 0.38%, and 2 tons of straw The calorific value of coal is equivalent to 1 ton of coal, and the average sulfur content of coal is about 1%; in addition, the fully burned straw ash can also be used as fertilizer to return to the field. Therefore, using pellet fuel as heating fuel has strong economic and social value.

  5. The pellet fuel has high volatilization rate and low ignition point, which can be directly used in coal-fired boilers.

  6. The pellet fuel produced by the wood pellet machine does not contain harmful chemicals. The ashes can be directly used in crops, and the ashes are rich in organic potassium. After coal is burned, it will produce a large amount of sulfur and phosphorus compounds and coal impurities, which will pollute the land if it is dumped everywhere.

  The above are the advantages of the pellet fuel produced by the wood pellet machine compared with coal. Promoting the use of environmentally friendly new energy fuels can not only save costs, but also help protect the environment. The development of wood pellet machines is bright.
