Product plan and scale

The product of this 2.5t/h wood pellet plant project is biomass pellets. Its products and their estimated production scale are shown in the table below.

Product nameAnnual output (t/a)SpecificationStorage location
Biomass pellets6000Φ8mmFinished product storage area 1, finished product storage area 2

Product output accounting:

This project uses 4 pellet machines, each with a production capacity of 500-700kg/h, and the production time of this project is 2400 hours/year. After calculation, the production equipment of this project can meet the production capacity requirements of this project. In the actual production process, the product output is adjusted according to the impact of customer orders. Therefore, the production equipment and production capacity of this project match.

Consumption of raw and auxiliary materials

Name of raw and auxiliary materialsAnnual usage tMaximum storage capacity tStatus/store methodRemarks
Wood scraps6000.41200Solid state stackingDry wood, sourced from wood processing enterprises in the surrounding and counties without painting, gluing, and anti-corrosion treatment, only left over after sawing, planing, milling, etc., the wood type is hard miscellaneous wood, and the wood does not contain Toxic and hazardous substances

Amount of raw and auxiliary materials:

The raw materials used in this 2.5t/h wood pellet plant project are wood scraps. During the production process, the raw materials will be lost due to the formation of dust due to crushing, pressing and molding processes. Pollution production coefficient is 6.69×10-4t/t-product), that is, the loss is 4.014t.

About 90% of the lost dust is collected into the pulse bag filter for treatment, and most of it is collected as raw and auxiliary materials after being treated by the pulse bag filter, and the dust that has not entered the pulse bag filter is discharged in the workshop without organization.

Most of them are settled on the workshop floor by gravity and collected by the construction unit as raw and auxiliary materials for reuse. Through calculation, the amount of recycled dust is 3.6046t.

It can be calculated that 6004.014 tons of raw materials are needed to produce 6000 tons of biomass pellets. Among them, 3.6046 tons of raw materials are recycled dust, so the annual consumption of raw materials is 6000.41 tons.

The villages near this project are mixed industrial and residential villages, and most of the industries are wood processing industries. Therefore, it is very convenient for customers to purchase raw materials.

Public and auxiliary works

① Water supply

The 2.5T/H wood pellet plant project is supplied with water by the municipal water supply network, with a water consumption of about 450t/a, which is mainly used for domestic water for employees.

② Drainage

The system of “rain and sewage separation” is implemented. The rainwater is collected and discharged into the local river. No production wastewater is generated in the project.

The domestic sewage is treated in a septic tank (canteen wastewater is passed through a grease trap) and then taken over to the sewage treatment plant, and the tail water is discharged into the sewage treatment plant.

③Power supply

The annual power consumption of the construction project is 1.1 million kW·h, which is provided by the municipal power grid, and the power supply is reliable, which can meet the needs of this project.

④ Storage and transportation

Raw materials are stored in raw material warehouses, finished products are stacked in finished product warehouses, in-factory transportation relies on forklifts and loaders, and out-of-factory transportation relies on social professional logistics companies.

⑤ Risk prevention

The project needs to build a fire pool of 80m3 and an emergency pool of 100m³. (Maybe you are interested in solution: small wood pellet plant)

2.5T/H Wood Pellet Plant Process Design

The granulation production process of this project is: crushing-crushing-feeding-granulation-cooling-packing and storage

  1. Chipping: Put the waste wood raw materials into the chipper and cut them into small pieces. Due to the large particle size of the raw material, there is basically no dust on the conveyor belt. The slicer operates in a semi-closed manner, and the upper part is the feeding port. After slicing, the material is basically still in the form of strips, and the particle size is relatively large.
  2. Crushing: Put the chipped waste wood into the crusher through the loader and crush it into plate materials with a particle size of about 10 cm to 80 cm.
  3. Screening: The crushed material is automatically conveyed to the screening machine by the closed conveyor belt to select some scrap metal and other waste impurities mixed in the raw material.
  4. Grinding: The screened materials are automatically conveyed to the mill for further grinding through the closed conveyor belt. The grinding diameter is 12mm. The grinding process is carried out in a closed manner, which will generate a small amount of grinding dust.
  5. Granulation: After grinding, the product is transported to the wood pellet press granulator through a closed conveyor belt. The wood pellet machine is the key equipment of the production line. The raw material contains a certain amount of cellulose and lignin, and the lignin is the structural monomer in the material.
    It is a high molecular compound, which can strengthen the cell wall and bind cellulose. Lignin is non-crystalline, the main part is insoluble in any solvent at room temperature, has no melting point, but has a softening point.
    When the temperature reaches a certain value, the softening cohesive force of lignin increases, and under a certain pressure, the cellulose molecular clusters are dislocated, deformed, and extended, and the adjacent biomass particles inside are engaged with each other, recombined and pressed forming.
  6. Cooling: The formed biomass wood pellets are transported to the finished product warehouse by a closed conveyor belt, and are slowly and naturally cooled during the conveyor belt transmission process, without drying or drying.
    Since the pellet size of the formed biomass pellet is relatively large (diameter 8mm~10mm, length 2-4cm), and the airtight transportation is adopted, the dust emission during the material transportation process is no longer considered.
  7. Packing: The cooled products are packed manually and stored for sale.

Note: The raw materials are transported to the raw material warehouse by forklifts, and the finished products are transported by forklifts.

Biomass pellets mainly refer to densely formed products of plant biomass, which is a renewable energy source. Its raw materials mainly come from straw, forest residues (residues from harvesting, timber making and processing), sawdust, peanut shells, bark, etc.

After being carbonized by a biomass wood granulator, it is processed into a diameter of about 8mm, and its length is its diameter. 5x or so block fuel.

As a new commercial energy source, biomass pellets have been widely used in various industries, and because of their high density, high calorific value, regular shape, and good fluidity, it is easy to realize automatic combustion control.

Special combustion equipment is convenient to carry out energy-saving transformation of existing industrial boilers, especially the transformation of boilers using biomass fuel instead of coal-fired boilers can save a large amount of energy costs and environmental protection costs for enterprises.

As a renewable energy source, biomass fuel is increasingly favored and valued by countries all over the world.

Biomass pellet fuel has huge potential to be explored. With the advancement of technology, the proportion of application is expected to increase significantly, and the prospect is promising. Therefore, the establishment of wood pellet plants and the development of biomass pellet are of great significance to alleviating the energy crisis and protecting energy security.
