Wood pellets are a kind of biomass energy that uses wood or other woody materials as raw materials. In different countries and regions, the types and standards of wood pellets may be different. Below we will introduce the types of wood pellets in detail.
Hardwood pellets
Hardwood pellets are wood pellets made from hardwoods such as oak, beech, maple, black walnut, etc. Hardwood pellets have a high calorific value, a long burning time, and produce less ash, which is not easy to produce smoke and dust, so it is favored by some high-end users. Hardwood pellets are characterized by high calorific value, long burning time, and less smoke and ash.
Cork pellets
Cork pellets are wood pellets made of cork, such as pine, fir, cypress, etc. The calorific value of cork pellets is relatively low, but the raw materials are cheap and easy to obtain, so they are more popular in the market. Cork pellets are characterized by a shorter burn time and more smoke and ash.
Mixed particles
Mixed pellets are wood pellets made by mixing a variety of wood as raw materials. The proportion can be adjusted according to different needs. The calorific value and quality of the mixed pellets depend on the ratio and quality of the raw materials. The characteristic of the mixed pellets is that the calorific value and burning time are both Between hardwood particles and softwood particles, the amount of smoke and ash is also relatively moderate. The advantage of mixed granules is that they can be formulated as needed to meet different usage requirements.
Straw pellets
Rice straw pellets are wood pellets made of rice straw, which can effectively utilize crop straw resources, reduce waste, and at the same time reduce environmental pollution caused by open-air burning of crop straw. The calorific value of straw pellets is relatively low, but the price of raw materials Cheap, is a relatively economical biomass fuel. The characteristics of straw pellets are that the burning time is short, and the amount of smoke and ash is large, so it is not suitable for burning for a long time.
Rice husk pellets
Rice husk pellets are wood pellets made from rice husks. It is a relatively new type of pellets. The advantages of rice husk pellets are easy access to raw materials, stable quality, high calorific value, and not easy to be affected by moisture and mildew. Rice husk pellets It is characterized by a short burning time, a large amount of smoke and ash, and is not suitable for long-term burning.
Palm Shell Granules
Palm shell pellets are wood pellets made from palm shells, and the main production area is Southeast Asia. The advantages of palm shell pellets are easy to obtain raw materials, stable quality, high calorific value, not easy to be affected by moisture, and not easy to mildew. Palm shell pellets are characterized by short burning time, more smoke and ash, and are not suitable for long-term burning.
