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

The core principle of wood pellet processing equipment, such as wood chip pellet mills, is to convert biomass feedstock into high-density pellet fuel through mechanical compression. The basic process involves three steps: feedstock pretreatment (crushing, pulverizing, and drying), mechanical compression, and finished product processing (cooling and packaging). For example, in a vertical ring die pellet mill, a motor connected to a reducer via a coupling drives the ring die. The feedstock enters the compression zone under gravity, where rollers squeeze the material into the ring die holes. After forming the pellets in the die, a cutter cuts them into pellets of fixed lengths.

2. Characteristics of dried wood pallets biomass pellet processing equipment

The  pellet processing equipment is a production line specifically designed for waste pallets (containing nails, metal connectors, and wood with uneven moisture and hardness). Its core features are tailored to the raw material characteristics, ensuring production efficiency, and optimizing finished product quality. The crushing stage processes the pallets into 25-55mm wood chips. The equipment design balances crushing efficiency with impurity tolerance. The pulverization stage processes pre-treated wood segments/chips into 2-5mm sawdust (the optimal particle size for pelletization). The drying stage controls moisture content and ensures pellet formation efficiency. The pelletizing stage forms the core and presses the powder into high-density pellets. The cooling and screening stages stabilize pellet properties and eliminate substandard products. The equipment in each stage works synergistically to transform raw materials into finished products.

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

Wood pellets (also known as "biomass pellet fuel") are a key alternative to traditional fossil fuels like coal and heavy oil due to their high combustion efficiency, low pollution emissions, and convenient storage and transportation. They are also the most popular application for wood pallet pellet processing equipment, including:

(1)Industrial Boiler/Kiln Fuel:Small and medium-sized boilers (steam boilers and hot water boilers) in the food processing, textile, chemical, and building materials industries, as well as heating equipment such as ceramic and glass kilns, can directly use wood pallet pellets (with a calorific value of approximately 4200-4800 kcal/kg, similar to medium-quality coal).

(2)Residential Heating/Household Energy:Wood pallet pellets can be used as fuel for household biomass heating stoves and fireplaces. The pellets burn stably (no black smoke or odor) and are automatically fed through a dedicated hopper, eliminating the need for frequent refills. Furthermore, some catering businesses (such as small restaurants) use them to replace liquefied petroleum gas for heating, reducing energy costs. 

(3)Power Plant Supplemental Fuel:Some biomass power plants mix wood pallet pellets with other biomass fuels, such as straw and sawdust, for power generation or combined heat and power (cogeneration) (generating both electricity and steam). The high density of wood pallet pellets (0.8-1.2 g/cm³) reduces transportation and storage space, lowering raw material storage costs for power plants. Furthermore, the high purity of the wood fiber (free of sand and impurities found in straw) reduces the risk of boiler slagging.

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.
