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

Dry wood biomass pellet processing equipment operates by converting dry wood waste (such as sawdust, shavings, and wood chips) into high-density, regularly shaped biomass pellet fuel through a series of physical processes. This process relies on mechanical extrusion and the natural bonding of lignin, eliminating the need for additional adhesives. The dry wood biomass pellet processing process can be summarized as follows: raw material pretreatment → extrusion molding → post-processing. Because the raw material is "dry wood" (with a moisture content typically controlled at 10%-15%), deep drying is not required. Instead, the process focuses on densifying the material through mechanical force and utilizing the heat generated during processing to activate the bonding properties of lignin, ultimately forming stable pellets.

2. Characteristics of dried wood log biomass pellet processing equipment

(1) Clean and environmentally friendly, with low pollutant emissions

As a biomass energy source, carbon emissions during combustion are close to "carbon neutral" (the CO₂ absorbed during the growth process of wood is basically balanced by the CO₂ released during combustion), which can reduce greenhouse gas emissions by more than 70% compared to coal.

The sulfur and nitrogen content is extremely low (usually sulfur <0.05%, nitrogen <0.1%), and almost no sulfur dioxide and nitrogen oxides are produced during combustion. No complex desulfurization and denitrification equipment is required, and it meets environmental emission standards (such as EU EN 14961-2 standard).

The ash content is low (high-quality wood pellets have an ash content of <0.5%), and there is little residue after combustion, which reduces the frequency of ash cleaning and waste residue treatment costs. 

(2) High combustion efficiency and stable thermal energy.

The low calorific value is generally 16-19MJ/kg (approximately 3800-4500 kcal/kg), close to that of medium-quality coal (4000-5000 kcal/kg), but it burns more completely (burnout rate > 95%) and can achieve a thermal efficiency of over 85% (much higher than the 50%-60% of direct combustion of loose wood chips).

The combustion process is stable and the flame is uniform, making it suitable as a continuous fuel for boilers, fireplaces, and biomass power plants. The energy supply can be precisely adjusted through an automatic control system.

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

Wood processing plants (such as furniture, wood flooring, and plywood factories) generate large quantities of dry sawdust, shavings, offcuts, and scraps during production. These waste materials have a low moisture content (typically ≤15% after natural air drying) and can be directly processed into pellet fuel through dry wood pellet processing without additional drying, thus achieving a "waste-to-energy" internal cycle:

(1)Self-use energy supply:The pellets produced can be directly used in the factory's heating system (such as boilers and kilns), replacing traditional coal and natural gas, reducing energy costs (biomass pellets are typically 30%-50% cheaper than natural gas) and lowering carbon emissions.

(2)Reduced waste disposal costs: Wood waste can be recycled through processing equipment, eliminating the need for waste accumulation and waste incineration (which can be polluting). Excess pellets can even be sold to generate additional revenue.

1. Market Prospects and Project Advantages of Dry Wood Processing Biomass Pellets

Driven by global environmental protection trends and growing demand for clean energy, processing dry wood into biomass pellet fuel has become a highly promising business opportunity. As a coal alternative, biomass pellet fuel continues to see growing market demand, boasting a calorific value of up to 4,000 kcal/kg. Meanwhile, the utilization rate of wood processing residues is less than 30%, leaving a significant unmet market demand for biomass pellet fuel. This presents a vast market opportunity for entrepreneurs.

This project also boasts core advantages such as policy support (environmental protection industries) and readily available raw materials (abundant waste from the construction and furniture industries), demonstrating its potential to replace coal.

2. Project Details of Dry Wood Processing Biomass Pellets

Project Process: First, dry wood is crushed into sawdust in a crusher. These sawdust are then fed directly into a pellet mill to be processed into biomass pellet fuel.

1.Environmental friendliness:

Dry wood pellets are typically made from wood waste and sawdust. This utilization method reduces wood waste and aligns with modern green production concepts. Furthermore, using dry wood pellets as fuel reduces dependence on fossil fuels, thereby reducing environmental pollution.

2.Energy-efficiency:

The production process for dry wood pellets typically requires low energy consumption and is highly efficient.

3.High combustion efficiency:

Dry wood pellets have a high combustion rate, with a calorific value of approximately 3,900 to 4,800 kcal/kg. After carbonization, the calorific value can even reach 7,000 to 8,000 kcal/kg. This makes them a highly efficient fuel option in the biomass energy sector.

4.Cleanliness:

Dry wood pellets contain no sulfur or phosphorus, are non-corrosive to boilers, and do not produce sulfur dioxide or phosphorus pentoxide. Therefore, they do not contribute to acid rain and pollute the atmosphere or the environment. Furthermore, their combustion produces minimal ash, reducing the space required for ash storage and the cost of ash removal.

5.Widely applicable:

Dry wood pellets can be used in a variety of applications. In the biomass energy sector, they can be used for power generation and heating. Dimensional stability: Dry wood particles are dried and hot-pressed during the production process, so they have good dimensional stability and strength and are not easy to warp or deform.
