1. Principle of wet wood pellet processing equipment

The core principle of wood pellet processing equipment (such as wood chip pellet machines) is to convert biomass feedstock into high-density pellet fuel through mechanical extrusion. The basic process includes three steps: feedstock pretreatment (crushing, drying, and screening), mechanical pressing, and finished product processing (cooling and packaging). For example, in a ring die pellet machine, a motor connected to a reducer via a coupling drives the ring die to rotate. Gravity forces the feedstock into the pressing zone, where the pressing rollers squeeze the material into the ring die holes. After being formed in the die, the pellets are cut into pellets of a fixed length by a cutter.

2.Characteristics of wet wood pellet processing equipment

(1) Wet wood biomass pellet processing equipment features high efficiency and low energy consumption. It can rapidly process biomass raw materials into fuel pellets, significantly improving production efficiency.

(2) The biomass pellet machine has strong material adaptability and is suitable for the molding of various biomass raw materials. The pellet machine is equipped with molds of various specifications.

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.

Advantages of Wet Wood as Biomass Pellet Fuel

When wet wood is processed into biomass pellet fuel, it offers numerous advantages, which are not only evident in environmental protection, economic aspects, and contributions to social development and energy structure improvement, but also in its unique combustion performance. The main advantages are as follows:

1. Calorific Value and Combustion Residue

The calorific value of wet wood biomass pellet fuel after combustion, as well as its ash content, is approximately 10% lower than that of medium - grade coal. However, wet wood biomass pellets burn out completely under normal working conditions. In contrast, coal cannot burn out entirely, leaving cinders with a combustible composition accounting for 10% to 15% of the total. As a result, in practical applications, the effective calorific values of the two are comparable.

2. Ignition Ease

Wet wood biomass pellet fuel has a better ignition property compared to coal. It ignites easily, significantly reducing the ignition time required for starting the combustion process.

3. Solid Emissions

The solid emissions of wet wood biomass pellet fuel are much lower than those of coal. This not only cuts down on the cost of slag disposal but also reduces environmental pollution. The solid emissions of wet wood biomass pellet fuel are mainly ash, accounting for about 0.4% - 7.0% of the total weight. In contrast, the solid emissions from coal combustion are a mixture of ash, alkali, and unburned coal, making up about 25% to 40% of the total weight.

4. Air Pollution and Corrosion

The degree of air pollution and boiler corrosion caused by coal is far greater than that of wet wood biomass pellet fuel. Coal soot contains a large amount of particulate carbon and toxic and corrosive gases such as SO₂ and CO. The main component of wet wood biomass pellet fuel is C - H organic matter. There is no particulate carbon and SO₂ gas in its flue gas. Instead, it mainly consists of C - H volatile gases, and its SO₂ and CO emissions are nearly zero. When burned, the smoke color is less than Ringelmann 1 level. This greatly reduces air pollution and carbon dioxide emissions, and wet wood biomass pellet fuel is internationally renowned as a "clean fuel."

5. Cost and Time Savings

Using wet wood biomass pellet fuel for boiler operation incurs less cost and time compared to burning coal. For example, a 0.5t boiler using wet wood biomass pellet fuel costs 11% less than when burning coal and saves 34% of the time. In another case, for a 0.5t boiler, the fuel cost relative to coal is reduced by 10%, and the time saved is 16%.

6. Continuous Combustion

The continuous combustion time of wet wood biomass pellet fuel is generally 8 to 10 times longer than that of soft, bulk materials. It can maintain a stable and continuous combustion state, ensuring a more reliable energy supply.
