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

The working process of the equipment includes the following main steps:

‌Feeding Stage‌: The raw materials enter the equipment through the feed port and are ready for the next step of processing.

‌Preliminary Crushing‌: Before the raw materials enter the compression chamber, they usually need to undergo preliminary crushing to ensure that the raw material particles are uniform in size, which is convenient for subsequent high-pressure compression and molding.

‌High-Pressure Compression‌: After the raw materials enter the compression chamber, they are subjected to strong compression force and are squeezed into strips or other shapes to enhance the bonding force between the particles.

‌High-Temperature Treatment‌: The compressed raw materials enter the high-temperature furnace for heat treatment to promote the pyrolysis and polymerization of components such as lignin, and further improve the calorific value and corrosion resistance of the particles.

‌Cooling And Molding‌: The raw materials after high-temperature treatment need to be cooled by the cooling system to prevent overheating, deformation or combustion, and then molded into regular granular solid fuels under the action of the mold or extrusion plate.

‌Discharging Stage‌: The molded particles are discharged through the discharge port to become the final biomass pellet fuel product.

2. Characteristics of  wet straw biomass pellet processing equipment

(2) Versatility: Not only suitable for straw, but also can process other biomass materials such as wood chips, peanut shells, rice husks, etc. This versatility makes it widely used in agriculture, energy and environmental protection industries. 

(3) High energy efficiency: Advanced power systems and energy-saving technologies are usually used to improve energy utilization efficiency, reduce energy consumption, and thus save operating costs. 

(4) High crushing uniformity: It can achieve uniform and fine crushing of biomass straw, making it easier to carry out subsequent fermentation, pressing or processing. 

(5) Automatic control: Many biomass straw crusher equipment is equipped with advanced automatic control systems, which can achieve intelligent operation, easy operation, and improve work efficiency. 

(6) Special materials and processes: The main load-bearing components are made of high-alloy wear-resistant materials, and the life of wearing parts is twice that of similar products.

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.

Advantages of Wet Straw Biomass Pellets

Processing straw into biomass pellets not only offers numerous advantages in environmental protection, economic and social development, and improving the energy structure, but also offers excellent combustion performance. The main advantages are as follows:

1. Calorific Value and Combustion Residues

The calorific value and ash content of straw biomass pellets after combustion are approximately 10% lower than those of medium-quality coal. However, straw biomass pellets burn completely under normal operating conditions. Coal, on the other hand, burns incompletely, leaving ash containing 10% to 15% combustible components. Therefore, in practical applications, the effective calorific value of the two is comparable.

2. Combustibility

Straw biomass pellets have better ignition properties than coal. They ignite easily, significantly reducing the ignition time required for combustion.

3. Solid Emissions

Straw biomass pellets have significantly lower solid emissions than coal. This not only reduces slag disposal costs but also reduces environmental pollution. Solid emissions from straw biomass pellets are primarily ash, accounting for approximately 0.4% to 7.0% of the total weight. In contrast, solid emissions from coal combustion consist of a mixture of ash, alkali, and unburned coal, accounting for approximately 25% to 40% of the total weight.

4. Air Pollution and Corrosion

Coal causes significantly higher levels of air pollution and boiler corrosion than straw biomass pellets. Coal smoke contains a large amount of particulate carbon as well as toxic and corrosive gases such as sulfur dioxide and carbon monoxide. Straw biomass pellets are primarily composed of C-H organic matter, and their flue gas contains no particulate carbon or sulfur dioxide. Instead, it is primarily composed of C-H volatile gases, with virtually no sulfur dioxide or carbon monoxide. The smoke color during combustion is below Ringelmann Class I, significantly reducing air pollution and carbon dioxide emissions, making straw biomass pellets an internationally recognized "clean fuel."

5. Cost and Time Savings

Compared to burning coal, using straw biomass pellets as a boiler fuel can save costs and time. For example, using straw biomass pellets in a 0.5-ton boiler can reduce fuel costs by 11% and shorten operating time by 34% compared to burning coal. For example, a 0.5-ton boiler can reduce fuel costs by 10% and shorten operating time by 16%.

6. Continuous Combustion

Straw biomass pellets typically burn 8 to 10 times longer than soft bulk materials, maintaining a stable and continuous combustion state, ensuring a more reliable energy supply.
