1. The working principle of  wet straw biomass pellet processing equipment

Wet straw biomass pellet processing equipment converts wet straw (such as corn straw and wheat straw) 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 wet straw biomass pellet processing process can be summarized as follows: raw material pretreatment (crushing, pulverization, drying) → extrusion molding → post-processing. Because the raw material is "wet straw" (usually with a moisture content of 10%-15%), deep drying is required. Instead, the process focuses on densifying the material through mechanical forces and utilizing the heat generated during processing to activate the binding properties of lignin, ultimately forming stable pellets.

2. Characteristics of  wet straw biomass pellet processing equipment

Pelletizing is the core process, and the equipment design revolves around "utilizing the natural bonding of lignin to ensure pellet density":

(1) Ring pelletizer: thick-walled ring die + large-diameter pressure roller. The ring die is made of double-layer wear-resistant alloy steel (wall thickness 15-20mm, ordinary ring die wall thickness 8-12mm), with high die hole finish (Ra≤1.6μm), which can withstand the severe friction of coarse fibers and has a service life of 300-500 hours (ordinary ring die is only 150-200 hours); the pressure roller diameter is increased to 180-220mm (ordinary pressure roller is 120-150mm), with a larger contact area and more uniform extrusion force, avoiding local overload and ring die cracking.

(2) Adhesive-free design, relying on frictional heat generation：the equipment precisely controls the gap between the roller and the ring die (0.1-0.3mm) and the rotation speed (200-300r/min), generating a high temperature of 60-90°C in the die hole, which is just enough to soften the lignin (lignin softening point is 50-80°C). This eliminates the need for artificial adhesives such as starch and resin, reducing costs and avoiding the generation of harmful gases (such as formaldehyde) during combustion.

3. Application scenarios of  wet straw biomass pellet processing equipment

(1) Industrial boiler fuel

Application targets: Industrial enterprises that require a stable heat source, such as textile mills, paper mills, food processing plants, and chemical plants (such enterprises traditionally rely on coal-fired boilers, which puts great pressure on environmental protection).

(2) Civilian clean heating/cooking

Application targets: Winter heating, home cooking, and decentralized energy needs in small places such as homestays and farmhouses.

(3) Biomass power generation/cogeneration

Application targets: Small and medium-sized biomass power plants (installed capacity 10-30MW), industrial park cogeneration projects (providing electricity and steam for the park).

(4) Agricultural and animal husbandry auxiliary

Application targets: Organic fertilizer production enterprises, flower and seedling planting bases.

The straw biomass pellet project utilizes abundant straw resources, transforming high-moisture, difficult-to-process waste into clean, renewable, and high-value-added biomass pellets.

This resource recycling project aims to address straw's solid waste pollution while generating clean energy to replace fossil fuels, achieving a win-win situation for both environmental and economic benefits. The key to the success of the straw biomass pellet project lies in three key aspects:

1. Matching raw materials with production capacity: Avoiding raw material shortages caused by overcapacity or raw material waste caused by insufficient production capacity;

2. Matching equipment with raw material characteristics: Using specialized straw pellet equipment can reduce equipment failures;

3. Matching products with market demand: Customizing product specifications based on the needs of local customers (factories, power plants, and residential applications) ensures stable sales. Furthermore, environmental compliance and cost control (raw materials, labor, and energy consumption are core cost items) must be prioritized. The project leverages policy support to reduce upfront investment, ultimately achieving a win-win situation for both environmental and economic benefits.

The core value of straw biomass pellets lies in their excellent energy supply. Their energy properties are reflected in the following aspects:

1. Calorific Value (Energy Density)

The calorific value of straw pellets typically ranges from 15-19 MJ/kg (megajoules per kilogram), with the specific value affected by the type of raw material, moisture content, and processing method.

Higher Calorific Value: Including the latent heat of water evaporation, approximately 18-20 MJ/kg.

Lower Calorific Value: Excluding the energy of water evaporation, approximately 15-17 MJ/kg.

Pelletization significantly increases the calorific value of straw, bringing it close to that of high-quality coal (approximately 20-25 MJ/kg).

2. Combustion Characteristics

Ignition Point: Approximately 250-300°C, lower than that of raw straw (uncompressed).

Combustion Efficiency: After pelletization, combustion efficiency can reach over 85%, with low residual ash content (typically less than 10%). Volatile Matter Content: Approximately 60-75%. Combustion easily releases combustible gases, promoting complete combustion.

3. Energy Density, Storage, and Transportation

Pelletization increases volumetric energy density by 3-5 times, facilitating storage, transportation, and large-scale applications (such as boiler fuel).

Moisture Control: The moisture content after processing is typically less than 10%, significantly reducing transportation costs and the risk of mold.

4. Renewable Energy Properties

Carbon Neutral: The CO₂ released during combustion is essentially balanced by the CO₂ absorbed during plant growth, meeting low-carbon and environmental requirements.

Sustainable Raw Materials: Utilizing agricultural waste (such as corn stalks and rice straw) as raw materials reduces incineration pollution and enables resource recycling.

5. Other Related Properties

Ash Composition: Primarily contains minerals such as potassium and calcium, and can be recycled as fertilizer.

Breakage Resistance: Pellets typically have a diameter of 6-8 mm and high compressive strength (approximately 3-5 MPa), making them suitable for long-term storage.
