Have you ever been plagued by mountains of waste wood, branches and leaves? If this is a real headache for you, we have great news: you’re actually sitting on a valuable resource pool—it just hasn’t been tapped yet. Wondering why we say that? Read on, and the answer will reveal itself.
Nowadays, coal resources are becoming increasingly scarce, and the massive harmful gases released during its combustion are causing worsening environmental pollution, leading to its gradual restriction. Once a vital mainstay for heating and power generation in the agricultural sector, coal is now facing obsolescence. This will undoubtedly impact people’s daily lives, creating an urgent need for a clean energy source that can replace coal.
Against this backdrop, biomass pellet fuel has emerged as the times require. You may already be familiar with biomass pellets, but do you know how they are produced?
In fact, the raw materials for biomass pellet fuel are extremely diverse and low-cost. Agricultural waste such as branches, leaves, offcuts from waste furniture, bamboo, and crop straw can all serve as feedstock for it.
Certainly, these raw materials need proper processing before production. For example, offcuts from waste furniture and crop straw must first be crushed by a wood crusher to reach the appropriate particle size. If the raw materials have a too high moisture content, they also need to be dried in a dryer. Of course, air-drying is a feasible option for small-scale production.
Once the raw materials are prepared, they can be processed by a wood pellet mill. In this way, agricultural waste, once regarded as useless trash, is transformed in the wood pellet mill into clean, high-efficiency pellet fuel.
After being compressed by the wood pellet mill, the raw materials see a dramatic reduction in volume and a significant increase in density. When burned, this pellet fuel produces no smoke at all, and its calorific value reaches an impressive 3000-4500 calories—with the specific value varying according to the type of raw materials used.
Therefore, converting agricultural waste into pellet fuel not only effectively addresses the disposal of the large amounts of agricultural waste generated in China each year, but also provides a viable alternative to fill the energy gap caused by the shortage of coal resources.
