1. The working principle of dried wood pallets biomass pellet processing equipment

The overall principle of wood pallet pellet processing equipment is essentially to transform "irregular, high-impurity, high-moisture" waste wood pallets into "regular, impurity-free, high-density, and easy-to-store" biomass pellets through the continuous physical processing of "dismantling and impurity removal → crushing and volume reduction → crushing and refinement → drying and moisture control → high-temperature and high-pressure molding → cooling and stabilization." No chemical agents are added throughout the process, and molding is achieved by relying on the adhesiveness of the wood's own fibers. This not only solves the problem of environmentally friendly disposal of wood pallet waste, but also achieves resource recycling (the pellets can be used as fuel, feed carrier, etc.).

2. Characteristics of dried wood pallets biomass pellet processing equipment

(1) Strong adaptability to raw materials, compatible with a variety of biomass

 Wide processing capacity: Processable raw materials include wooden pallets, old furniture, demolition materials, etc. By adjusting the crushing and pulverizing equipment, it can adapt to raw materials of different hardness and fiber content.

 Clear requirements for raw material pretreatment: The moisture content of the raw materials must be controlled at 10%-15% (too high a moisture content will easily cause adhesion and mold clogging, while too low a moisture content will result in insufficient particle strength), and the particle size is usually required to be 1-3mm.

(2) Modularization of core equipment and continuous production process

 Modular combination: A typical production line consists of "crushing equipment (coarse crushing) → crushing equipment (fine crushing) → drying equipment (humidification) → granulating equipment (molding) → cooling equipment (cooling) → screening equipment (screening) → packaging equipment". Each module can be flexibly increased or decreased according to production capacity requirements (for example, for small production lines, some auxiliary equipment can be omitted).

Continuous operation: Through the connection of various links such as conveyor belts and screw feeders, automated continuous production from raw material input to finished product output is achieved.

3. Application scenarios of dried wood pallets biomass pellet processing equipment

Processing equipment provides fuel for factory boilers and kilns (replacing coal and oil), such as steam boilers in textile and food processing plants, and heating kilns in the ceramics and building materials industries. Stable pellet production ensures energy supply.

(1)Power Generation:Biomass power plants require large quantities of standardized pellets as fuel. Large-scale processing equipment can meet the power plant's stringent requirements for pellet calorific value and density, ensuring efficient combustion and stable power generation.

(2)Residential Heating:For pellets used in home fireplaces and space heaters, processing equipment must control pellet size and hardness to accommodate residential combustion equipment. The equipment's refined production capabilities directly impact the user experience of these pellets.

(3)Environmental Protection and Waste Management:In waste and sewage treatment plants, processing equipment converts organic waste (such as sludge and food waste) into fuel pellets for resource recovery. Corrosion-resistant and clogging-resistant designs are crucial.

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.

Advantages of Wood Pallet Pellets

Processing wood pallet pellets into biomass pellets not only offers numerous advantages in terms of environmental protection, economic and social development, and energy structure, but also boasts excellent combustion performance. The main advantages are as follows:

1. Calorific Value and Combustion Residues

The calorific value and ash content of biomass pellets after combustion are approximately 10% lower than those of medium-quality coal. However, pellets burn completely under normal operating conditions. Coal, on the other hand, does not burn completely, leaving residual ash containing 10% to 15% combustible components. Therefore, in practical applications, the effective calorific value of the two is comparable.

2. Combustibility

Pellets are more flammable and easy to ignite than coal, significantly reducing the ignition time required for combustion.

3. Solid Emissions

Biomass pellets produce significantly lower solid emissions than coal. This not only reduces slag disposal costs but also reduces environmental pollution. Solid emissions from biomass pellets are primarily ash, accounting for approximately 0.4% to 7.0% of the total weight. In contrast, solid emissions from coal combustion are a mixture of ash, alkali, and unburned coal, accounting for approximately 25% to 40% of the total weight. 4. Air Pollution and Corrosion

Coal causes far greater levels of air pollution and boiler corrosion than wood biomass pellets. Coal smoke contains large amounts of particulate carbon, as well as toxic and corrosive gases such as sulfur dioxide and carbon monoxide. Biomass pellets are primarily composed of C-H organic matter, and their flue gas contains no particulate carbon or sulfur dioxide. Instead, it consists primarily of C-H volatile gases, with virtually no sulfur dioxide or carbon monoxide. The smoke color during combustion is below Ringelmann Class I, significantly reducing air pollution and carbon dioxide emissions. Biomass pellets are internationally recognized as a "clean fuel."

4. Cost and Time Savings

Compared to coal, using biomass pellets as boiler fuel can save costs and time. For example, using wood biomass pellets for a 0.5-ton boiler can reduce costs by 11% and time by 34%. For example, compared to coal-fired power generation, a 0.5-ton boiler can reduce fuel costs by 10% and time by 16%.

5. Sustained Combustion

Wood biomass pellets typically burn 8 to 10 times longer than loose, soft materials, maintaining a stable and continuous combustion state, ensuring a more reliable energy supply.
