What factors affect the calorific value of biomass pellets in wood pellet mills? Quick look

Biomass pellets are an environmentally friendly fuel processed by sawdust pelletizers that emerged with the concept of environmental protection. Biomass pellets are processed from crop wastes, such as straw, peanut shells, bark and other materials. By using biomass Pellet can replace coal and other polluting fuels, and has an environmental protection effect. At the same time, because the raw materials for processing are waste, the cost price of biomass pellets is much lower than that of coal, but many users worry that the calorific value of biomass pellets will reach It does not meet the needs of its own use, which leads to the fear of using biomass pellets from wood pellet mills.

In fact, these concerns are not unreasonable, but as long as you understand the factors that affect the calorific value of biomass pellets, you don't have to worry about this problem. What are the factors that affect the calorific value of biomass pellets? Let's find out together.

The first is the raw material for making biomass pellets. In general, the calorific value of peanut shells is lower than that of straw, and the calorific value of straw is lower than that of bark. This is because different materials burn When the calorific value is different, the calorific value generated is naturally different, and the density that can be processed by different materials is also different, so it will naturally affect the calorific value of the biomass particles, so in the choice of At the same time, the calorific value of biomass particles can be controlled to meet the requirements by selecting raw materials.

Then there is the influence of the moisture content in the biomass particles, which is well understood, because the more moisture of the same volume of biomass particles, the less combustibles, and in the process of combustion, the evaporation of water will also take away heat.
