1. The working principle of wet wood log biomass pellet processing equipment

The principle of wet sawdust pellet processing equipment is to compress wet sawdust into pellets by physical means. During the pelletizing process, the biomass sawdust raw materials fall vertically from the feed port. The rotation of the pressing wheel makes the material continuously and evenly distributed on the surface of the inner cavity of the mold. Under the rolling of the pressing roller, the powdered material passes through the hole of the mold. In this process, the material is subjected to high pressure and high temperature, which causes physical changes or appropriate chemical changes, prompting the powdered material to form a continuously elongated cylindrical solid body. The pellets are then cut by the cutting knife and discharged from the discharge port. At this point, the pellet pressing process is completed.

2. Characteristics of wet wood log  biomass pellet processing equipment

(1) Efficient molding and stable pellet quality. The core equipment, the ring die pelletizer, uses high-strength alloy ring die and wear-resistant pressure roller, which can withstand the high friction when wet sawdust is squeezed, ensuring continuous production.

(2)It has strong adaptability to high-moisture raw materials and can quickly reduce the moisture content to the 10%-15% required for pelleting. It can also operate stably even if the raw material humidity fluctuates greatly (such as sawdust collected in the rainy season).

(3)  Energy saving and environmental protection, high resource utilization

(4) High degree of automation and convenient operation. It can monitor raw material moisture, granulation temperature, output and other parameters in real time, automatically adjust drying time, feeding speed, roller speed, etc., and reduce manual intervention.

3. Application scenarios of wet wood log biomass pellet processing equipment

(1) Industrial energy field: Processed pellet fuel can be used as fuel for industrial equipment such as boilers, hot air furnaces, dryers, etc., replacing traditional fossil energy and reducing corporate carbon emissions.

(2)  Agricultural recycling: Processing wet waste such as corn stalks and peanut shells generated in agricultural production, converting them into heating fuel for breeding or raw materials for organic fertilizer, thus realizing resource recycling

(3)  Environmentally friendly waste treatment: Reduce the amount of wet wood log chips and sawdust generated by the wood processing industry, reduce landfill volume, and meet green production requirements

TONY Brand 4-5Ton/Hour Wet Wood  Log Pellet Manufacturing Plant can take wet wood log, various types of wood - related biomass materials, such as branches, small - diameter logs, and wood shavings, with wet wood  log as the main raw material.

Biomass pellet fuel, due to its clean, environmentally friendly, high calorific value, and stable combustion properties, is widely used in industrial boilers, heating equipment, livestock farms, and food processing. With the advancement of the national "coal to biomass" policy, the phase-out of traditional coal-fired boilers is accelerating, and market demand continues to grow.

2. Utilizing agricultural waste to convert energy aligns with the "dual carbon" goals and has gained both policy and public recognition.

3. It is a labor-intensive industry that can create rural jobs and contribute to rural economic development.

4. With stable production technology, franchisees can access technical support and operational solutions, lowering the barrier to entry for entrepreneurs.     

5. Biomass pellet processing projects offer both environmental benefits and economic potential, making them suitable for rural areas with favorable policies and abundant raw materials. By rationally controlling costs, selecting high-quality equipment, and precisely matching market demand, they are expected to achieve stable profitability.

Advantages of Wet Wood Log  as Biomass Pellet Fuel

When wet wood log is processed into biomass pellet fuel, it offers numerous advantages, which are not only evident in environmental protection, economic aspects, and contributions to social development and energy structure improvement, but also in its unique combustion performance. The main advantages are as follows:

1. Calorific Value and Combustion Residue

The calorific value of wet wood  log biomass pellet fuel after combustion, as well as its ash content, is approximately 10% lower than that of medium - grade coal. However, wet wood log biomass pellets burn out completely under normal working conditions. In contrast, coal cannot burn out entirely, leaving cinders with a combustible composition accounting for 10% to 15% of the total. As a result, in practical applications, the effective calorific values of the two are comparable.

2. Ignition Ease

wet wood log biomass pellet fuel has a better ignition property compared to coal. It ignites easily, significantly reducing the ignition time required for starting the combustion process.

3. Solid Emissions

The solid emissions of wet wood log biomass pellet fuel are much lower than those of coal. This not only cuts down on the cost of slag disposal but also reduces environmental pollution. The solid emissions of wet wood log biomass pellet fuel are mainly ash, accounting for about 0.4% - 7.0% of the total weight. In contrast, the solid emissions from coal combustion are a mixture of ash, alkali, and unburned coal, making up about 25% to 40% of the total weight.

4. Air Pollution and Corrosion

The degree of air pollution and boiler corrosion caused by coal is far greater than that of wet wood log biomass pellet fuel. Coal soot contains a large amount of particulate carbon and toxic and corrosive gases such as SO₂ and CO. The main component of wet wood log biomass pellet fuel is C - H organic matter. There is no particulate carbon and SO₂ gas in its flue gas. Instead, it mainly consists of C - H volatile gases, and its SO₂ and CO emissions are nearly zero. When burned, the smoke color is less than Ringelmann 1 level. This greatly reduces air pollution and carbon dioxide emissions, and wet wood log biomass pellet fuel is internationally renowned as a "clean fuel."

5. Cost and Time Savings

Using wet wood log biomass pellet fuel for boiler operation incurs less cost and time compared to burning coal. For example, a 0.5t boiler using wet wood log biomass pellet fuel costs 11% less than when burning coal and saves 34% of the time. In another case, for a 0.5t boiler, the fuel cost relative to coal is reduced by 10%, and the time saved is 16%.

6. Continuous Combustion

The continuous combustion time of wet wood log biomass pellet fuel is generally 8 to 10 times longer than that of soft, bulk materials. It can maintain a stable and continuous combustion state, ensuring a more reliable energy supply.
