1. Principle of wet wood pellet processing equipment

The core principle of wood pellet processing equipment (such as wood chip pellet machines) is to convert biomass feedstock into high-density pellet fuel through mechanical extrusion. The basic process includes three steps: feedstock pretreatment (crushing, drying, and screening), mechanical pressing, and finished product processing (cooling and packaging). For example, in a ring die pellet machine, a motor connected to a reducer via a coupling drives the ring die to rotate. Gravity forces the feedstock into the pressing zone, where the pressing rollers squeeze the material into the ring die holes. After being formed in the die, the pellets are cut into pellets of a fixed length by a cutter.

2.Characteristics of wet wood pellet processing equipment

(1)Wet wood biomass pellet processing equipment features high efficiency and low energy consumption. It can rapidly process biomass raw materials into fuel pellets, significantly improving production efficiency.

(2)The biomass pellet machine has strong material adaptability and is suitable for the molding of various biomass raw materials. The pellet machine is equipped with molds of various specifications. According to different biomass raw materials, the corresponding mold can be selected for processing, enhancing the adaptability of processing.

(3)The design of wet - wood biomass pellet processing equipment is mature. The finished pellets have stable molding, stable output, and high quality.

(4)Biomass pellet processing equipment is simple to operate, easy to use, has a high degree of automation, requires less labor, effectively reduces labor intensity, and improves production.

3. Application scenarios of wet wood pellet processing equipmen

1. Outstanding Environmental Protection and Low Carbon Emissions

Carbon Neutral: Wood pellet fuel is derived from wood processing waste (such as wood chips and sawdust) and is a biomass energy source. The carbon dioxide absorbed during plant growth is roughly balanced by the carbon dioxide released during combustion, making it a "carbon-neutral" energy source, significantly reducing its contribution to the greenhouse effect.

Low Pollutant Emissions: Compared to coal, wood pellets produce extremely low levels of pollutants such as sulfur dioxide and nitrogen oxides (often far below environmental standards) when burned, and dust emissions are also low, effectively reducing air pollution and meeting increasingly stringent environmental regulations.

2. Wide Source of Raw Materials and Controllable Costs

Abundant Raw Materials: The main raw materials are scraps, wood chips, sawdust, branches, and bark generated during wood processing. These materials are readily available and stable in forestry, furniture manufacturing, and papermaking. They can even be "turned waste into treasure," reducing the environmental impact of landfills or incineration.

Cost Advantages: The raw materials are mostly industrial waste, resulting in relatively low procurement costs. Furthermore, some regions offer subsidies for biomass energy projects, further reducing production and usage costs. Compared to other energy sources like natural gas and fuel oil, biomass energy is economical.

3. High Combustion Efficiency and Efficient Energy Utilization

High Density: Wood pellets are compressed and formed, resulting in a density significantly higher than that of raw wood or sawdust (typically 1.1-1.3 tons/cubic meter). They are less prone to loosening during combustion, maintaining a stable combustion state and a long-lasting flame. They also offer high thermal efficiency (typically exceeding 85%, compared to the 40%-50% of loose firewood).

Stable Combustion: The pellets have a regular shape and uniform size, facilitating automated feeding and combustion control. They can be precisely adjusted with a matching pellet stove, reducing energy waste and making them suitable for applications requiring a stable heat source.

4. Convenient Storage and Transportation

Small Size: Compressed pellets are only 1/5-1/8 the volume of raw sawdust, significantly saving storage space. They can be stored in bags or in bulk, eliminating the need for specialized storage facilities, making them suitable for homes, businesses, and other environments.

Low Transportation Costs: The high density allows for higher energy transport per unit volume, improving transportation efficiency and reducing transportation costs. Furthermore, the pellets are resistant to moisture (some products are treated to prevent moisture), minimizing loss during transportation.

5. Diverse Application Scenarios

Civilian Applications: They can be used for home heating and cooking (using devices such as pellet fireplaces and pellet stoves). They are simple and clean to operate, replacing traditional coal and firewood to improve the indoor environment.

Industrial Applications: They can be used as boiler fuel to provide steam or hot water for factories, hotels, and hospitals. In agriculture, they can be used for greenhouse heating and drying agricultural products (such as grains and medicinal herbs).

Power Generation: They can be used as fuel in biomass power plants, either mixed with coal or burned alone to generate electricity, contributing to the transformation of the energy structure.

1.Environmentally friendly features

(1)Low pollution emissions: The sulfur and phosphorus content during combustion is extremely low, and the concentration of SO₂ and NOx in the flue gas is much lower than that of coal. It will not produce acid rain, and CO₂ emissions are zero (because plants absorb CO₂ during growth)

(2)Ash utilization: Ashes after combustion are rich in organic potassium and can be recycled as high-efficiency organic fertilizer

2.Economical

(1)Wide range of raw materials: waste such as wood processing waste and crop straw can be used, and the production cost is lower than traditional fossil fuels.

(2)Substitution benefits: Replacing coal can save about 20% to 30% of fuel costs 

3.Wide range of application scenarios

(1)Industrial applications: Widely used in boiler heating, power generation and industrial production, such as textile factories, food factories, etc.

(2)Civil heating and living energy: Wood pellets have high combustion efficiency, are easy to store and use, and are safe and hygienic.

(3)Biomass industrial boiler: As the main fuel for industrial boilers, it replaces coal, heavy oil and natural gas to solve environmental pollution problems.
