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

Wet wood biomass pellet processing equipment is used to chop and compress bundles or packets of wet - wood and other biomass raw materials into pellet fuel. Its working principle is to first chop the wet - wood raw materials through shredders and other pretreatment equipment. Then, it is pressed through the pelletizing machine, and finally, pellet biomass fuel that meets quality standards is produced.

2.Characteristics of wet wood log biomass pellet processing equipment

Wood pellet processing equipment (i.e., wood biomass pellet machines and supporting production lines) is designed specifically to process wood materials such as sawdust, wood chips, and branches into high-density pellets.

It is compatible with a wide range of wood materials: it can process sawdust, wood chips, shavings, wood chaff, chopped branches, and waste wood. Whether softwood (such as pine and fir) or hardwood (such as oak and birch), it can be efficiently processed after pre-treatment (crushing and pulverization).

To address fluctuations in raw material moisture: Dedicated drying equipment (such as drum dryers) can control the moisture content of the wood raw material to 10%-15% (the optimal moisture range for wood pellet production), avoiding problems such as blockage and loose pellets caused by over-moisture.

Flexible particle size processing: The accompanying pulverizer can crush the wood raw material to the size of sawdust, meeting the pellet mill's fineness requirements and ensuring uniform pellet formation.

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

(1) Domestic solid fuel:

Wet - Wood Log Pellet  fuel has a high utilization rate, is convenient for storage and use, and is hygienic and safe. It can be used for home heating.

(2) The main solid fuel for industrial boilers:

It can replace raw coal, heavy oil, and gas, reducing air pollution. For every 10,000 tons of biomass fuel burned, it can replace 7,000 tons of standard coal, reduce SO₂ emissions by 165 tons, smoke and dust emissions by 80 tons, and carbon dioxide emissions by 14,400 tons.

(3) Thermal power generation:

The fuel calorific value can reach 3400 - 6000 kcal.

In simple terms, wet - wood biomass pellet fuel can be described as "environmentally friendly", "energy - saving", "renewable", and "with zero carbon emissions". Biomass fuel is the best renewable energy source to replace coal. From the perspectives of cost, energy conservation, and environmental protection, biomass fuel is a better alternative to coal. 

TONY Brand 24-30 Ton/Hour Wet Wood Log Pellet Manufacturing Plant can take wet wood, various types of wood - related biomass materials, such as branches, small - diameter logs, and wood shavings, with wet wood as the main raw material. After pretreatment and processing, it is solidified into high - density wood pellet fuel. This fuel is an ideal substitute for coal and oil and plays a role in energy conservation and emission reduction. At present, it has been widely used in regions rich in wood resources.

1. With the increasingly severe energy and environmental crisis, biomass energy, as a renewable and clean energy source, has received growing attention. Taking crop straw as an example, its potential for in - depth development is enormous. There are various ways to utilize biomass, and processing biomass into compressed pellet fuel is an advanced approach to biomass utilization. The sulfur content in biomass pellet fuel is less than one - tenth of that in coal. Replacing coal combustion with it can effectively reduce the emission of sulfur dioxide in the atmosphere, and the ash generated after combustion is an excellent natural fertilizer. At present, the gasification combustion of biomass pellets is a clean and environmentally friendly combustion mode, which is of great significance for reducing pollution emissions and protecting the atmospheric environment.

2. Crop straw, as an extremely important resource in agricultural production, is very common in rural areas and exists in huge quantities. For a long time, there has been a lack of good treatment methods for straw. If it is burned on - site, it will cause pollution to the environment. However, choosing straw as the raw material for biomass pellets results in extremely low raw material costs. If there are a large number of straw resources in or around the area, the raw material cost can be almost negligible.

3. Biomass fuel is not only environmentally friendly but also provides an option for the country's energy needs. The market demand for biomass fuel is constantly increasing, and the price of biomass pellet energy made from straw is also rising steadily. For entrepreneurial projects, there is a considerable profit margin. Therefore, using straw to produce biomass pellets has multiple benefits. Besides protecting the environment and helping to solve employment problems, it can also bring considerable economic benefits and ensure the sustainability of energy.

As a biomass energy source, wood pellets have significant environmental protection characteristics and energy benefits. In terms of environmental protection, its production process does not contain any chemical additives, and it is smokeless and odorless when burned, has no pollution to the environment, and meets environmental protection requirements.

Compared with traditional coal, its carbon dioxide emissions are 97.91% less than coal, sulfur dioxide emissions are 99.15% lower than coal, and nitrogen dioxide emissions are 72.09% less than coal, almost achieving zero pollution emissions. At the same time, its raw materials are mainly agricultural and forestry waste, such as branches, sawdust, straw, etc., which are renewable energy sources and effectively realize the recycling of resources. In terms of energy efficiency, the calorific value of wood pellet fuel can reach 3600-4200 kcal/kg, and the thermal efficiency can reach more than 85% when using a special biomass heating furnace, which has a high energy density.
