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

The wet straw pellet processing equipment uses wet straw as raw material, firstly processes it into sawdust-like raw material that meets the pelleting requirements through crushing and pulverizing equipment, then dries the pulverized material to control the moisture content, and then uses a biomass pellet machine to extrude the dried material into shape, and finally obtains the finished pellets after cooling and packaging. The whole process converts the originally discarded wet straw into usable pellet fuel, realizing the recycling and reuse of resources.

2. Characteristics of  wet straw biomass pellet processing equipment

(1)Efficient pelletizing and stable pellet quality. The core equipment, the ring die pelletizer, utilizes a high-strength alloy ring die and wear-resistant rollers to withstand the high friction of wet straw compression, ensuring continuous production.

(2)Highly adaptable to high-moisture raw materials, it can quickly reduce moisture to the required 10%-15% for pelleting. Even with large moisture fluctuations (such as sawdust collected during the rainy season), stable operation is maintained.

(3) Energy-saving and environmentally friendly, with high resource utilization.

(4)Highly automated and easy to operate, it monitors parameters such as raw material moisture, pelletizing temperature, and output in real time, automatically adjusting drying time, feed rate, roller speed, and other parameters to minimize manual intervention.

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.

1. Current Market Demand for Straw Pellets

Currently, straw pellets are not widely used in most parts of my country, primarily due to low market awareness, an imbalance between supply and demand, and immature technology. However, with national policies promoting green and environmentally friendly energy and supporting the industry, market demand for straw pellets is gradually growing. According to Zhilian Data, market demand for straw pellets has reached millions of tons, while supply only accounts for approximately 2% of the national bamboo production, creating a significant supply-demand imbalance.

2. Market Prospects for Straw Pellets

As a renewable fuel, straw pellets offer promising market prospects. First, they align with national policies on environmentally friendly and green energy, resulting in broad market demand. Second, straw pellets have a wide range of uses, including home heating, industrial heating, and power machinery fuel, creating a significant market opportunity. Furthermore, straw pellets have relatively low production and transportation costs, offering significant market advantages. Furthermore, as technology matures and production efficiency and output continue to rise, the competitiveness of straw pellets will continue to improve.

In short, the straw pellet fuel market has broad prospects, and its status will continue to rise with the development of China's economy and changes in the policy environment. Currently, related industry companies need to further strengthen technological research and development, improve product quality, and improve the market supply chain to ensure market prospects and production and sales market share.

1. Economical and Applicable.

Straw processed into pellet fuel has a calorific value of 15,100 to 16,800 kJ/kg and sells for around 450 yuan/ton. This price is 50 to 80 yuan/ton more than coal of the same calorific value (excluding energy savings and pollution fees), and significantly lower than diesel and natural gas. Biomass (pellet) gasification boilers offer significant economic advantages. Replacing oil, gas, or electric boilers can save users significant operating costs. While similar in price to coal, its superior environmental performance and recyclability are unmatched by coal-fired boilers. Due to its high volatility and flammability, straw fuel has a wide range of applications. For example, it can be used directly in coal-fired boilers with a capacity of less than 1 ton/h, tea bath furnaces, and low-temperature kilns for drying and heat treatment. With minor furnace modifications, it can also be used in larger boilers and special-purpose kilns with appropriate measures.

2. High combustion efficiency and energy conservation

Because straw fuel has high volatility, low ash and moisture content, and is easily flammable, heat loss from incomplete combustion, including mechanical, chemical, and smoke exhaust, is minimized, resulting in a combustion efficiency exceeding 95%.

In summary, wet straw biomass pellets offer the advantages of bein
