8T/H Biomass Wood Pellet Production Line in South Korea

Project construction content and construction scale

The wood pellets plant has a construction area of 2905m2. It will purchase sawing machines, cutters, planers, combing machines, jointing machines and other equipment to produce related products.

After the wood biomass pellet plant project is completed, it will have an annual production capacity of 50,000 sets of paint-free doors, 5,000 m3 of flame-retardant wood, 10,000 m3 of finger joints, and 20,000 tons of biomass pellets. After the completion of this project, the main product names and output of the whole plant are detailed in the table below.

Quality standards for wood pellets in South Korea

The quality standards for wood pellets in South Korea include indicators such as particle size, moisture content, ash content, sulfur content, and nitrogen content. Among them, particle size refers to the size of the diameter of the wood pellets.

The standard stipulates that the diameter should be between 6mm and 8mm; the moisture content and ash content should be within the corresponding standard range; the sulfur content and nitrogen content should also meet the corresponding standard requirements.

Main wood pellet equipment of the project

South Korea 8T/H Wood pellet plant process design

Brief description of wood pellets production process：

1. After the raw materials arrive at the site, some of them need to be crushed, and then loaded by a loader and lifted into the silo (the pelletizing extrusion compression equipment can reach about 100℃-120℃, and its own high temperature can be used to remove moisture);
2. The silo is equipped with a level meter to control the loading of the elevator to prevent the elevator from stopping after the silo is full;
3. A drum screen (with a magnet inside) is set at the bottom of the silo. Because some wood chip raw materials contain iron tools such as iron nails, iron impurities are removed to ensure product quality.
4. The working principle of the wood pellet mill is similar to that of the feed pellet machine, that is, the raw materials are added from the inside of the ring die (the moisture content of the raw materials is required to be preferably 11%-14%, and it is difficult to granulate if the moisture content is too large or too small), and the raw materials are rolled and extruded from the ring die to form granules. The extrusion pressure reaches 50-100MPa, and the raw materials are deformed and heated under high pressure.
5. After being made into granules, they are lifted into the silo by a belt conveyor and cooled and screened by an air-cooled cooling unit
6. After screening, the particles that do not meet the specifications are recovered and returned to the silo.
7. Qualified pellets are loaded by bucket elevators to the silo to be packaged, packaged by computer quantitative packaging machines, and then stored and sold in warehouses.

The raw and auxiliary materials are wood chips and shavings, and no adhesives or additives are added during the production process.

The scraps, wood chips and dust collected by the central dust collection system during the paint-free door, flame-retardant wood and finger-jointing process are collected and reused in the production of biomass pellets.

Public works

Supporting facilities

• Water supply system: supplied by the water company.
• Power supply system: connected to the nearest power grid by the power supply department.

Drainage

The wastewater of this 8t/h biomass wood pellet production line in South Korea project is mainly domestic sewage of employees.

After the domestic sewage is pre-treated in the septic tank and meets the "Water Quality Standard for Sewage Discharge into Urban Sewers" together with other wastewater, it is discharged into the sewage treatment plant.

Pollution prevention and control measures

The environmental protection measures taken by this 8t/h biomass wood pellet production line in South Korea project are as follows:

Environmental protection requirements for wood pellets in South Korea

In order to protect the environment, South Korea has very strict environmental protection requirements for wood pellets.

• First, imported wood pellets must meet South Korea's environmental protection standards and cannot cause pollution to the environment.
• Secondly, the emission of waste and exhaust gas should be reduced during the production process of wood pellets, and green production should be achieved.

The prospects for building biomass wood pellet production line in South Korea in South Korea

In recent years, the demand for industrial wood pellets in South Korea has grown rapidly and is expected to grow significantly in the next decade. The wood pellet market in South Korea has gradually emerged because it is widely used in the field of bioenergy and its renewable energy properties are widely recognized.

According to a survey report from the Korea Bioenergy Association, the total output of wood pellets produced in South Korea in 2023 is 421,700 tons, and it is expected to grow at a rate of 10% per year.

So, ‌the prospects for processing wood pellets in South Korea are quite optimistic.

• First, South Korea's demand for wood pellets continues to grow. According to statistics, as of September 2024, South Korea's imports of wood pellets increased by 41.9% year-on-year, showing that the market demand for wood pellets is increasing. In addition, South Korea imports a large amount of logs from countries such as New Zealand, the United States, Australia, Germany and Canada, which also provides a sufficient source of raw materials for the production of wood pellets.
• Secondly, wood pellets have a wide range of applications. Wood pellets can be used as biomass fuel in biomass power plants, fuel plants, industrial boilers and drying plants, etc., replacing traditional coal and other fuels. This transformation not only meets environmental protection requirements, but also reduces the operating costs of enterprises.

However, the Korean wood pellet market also faces some challenges.

1. First, its domestic wood supply is in short supply and the price of imported wood has risen, resulting in fierce competition for raw material security.
2. Secondly, the price and circulation system of logs are affected by loggers, and the price of wood fluctuates greatly.
3. In addition, South Korea's increased demand for renewable energy has also made the demand for wood pellets more dependent on policy and market changes.

Overall, the outlook for the Korean wood pellet market is optimistic, but attention needs to be paid to issues such as raw material supply and price fluctuations.
