Biomass Pellet Manufacturing Proposal Of The 50 Tons Per Day Biomass Pellet Plant For Bio Fuel Pellets From Wood Straw Bamboo Powder

Origin of the 50 tons per day complete biomass pellet plant

Because the development of biomass pellets is restricted by factors such as raw materials, climate, and production costs, the government's efforts to encourage its development are not strong enough, and the development speed has not been fast.

However, with the continuous deterioration of the environment, the continuous improvement of people's awareness of environmental protection, and the non-renewable nature of natural resources, people are more concerned about "low-carbon, environmentally friendly" biomass pellet fuel.

Especially biomass pellet fuel, with its simple pellet production process, high product density, high calorific value, high combustion efficiency, environmental protection and other characteristics, makes people's attention to energy demand further aligned.

The 50 tons per day biomass pellet plant project client - Fujian Yuanzhusheng Agriculture and Forestry Technology Development Co., Ltd. is a manufacturer of lignin series functional materials. The biomass fuel company focuses on extracting lignin from the rich bamboo resources in Lexian County as raw materials, and to produce high-efficiency lignin, coal-water slurry additives, dispersants, viscosity reducers and other products.

In recent years, the customer company has researched the reasonable ratio of wood scrap powder, straw powder and bamboo lignin as raw materials, and the high-efficiency biomass pellet fuel produced has higher combustion efficiency and is more environmentally friendly.

Therefore, the company decided to invest in the construction of a complete biomass pellet plant project with an annual output of 15,000 tons through research, so that the production of this biomass pellet fuel can be industrialized, scaled and standardized as soon as possible, and quickly extended to industrial production, service fields and civil aspect.

Since this 50 tons per day complete biomass pellet plant project is an industry-university-research project, a 4-ton test boiler is required to test products for this biomass pellet plant project and provide energy for its production. The excess energy is supplied to the customer's own company's production gas.

This 50 tons per day complete biomass pellet plant project is located in Jishan Park, Jiangle Economic Development Zone, Jiangle County, Fujian Province. The 50 tons per day complete biomass pellet plant project land is leased to an open space for construction and production. The land is industrial land.

• Construction Nature: New build
• Factory area: 1000㎡.
• Production scale: Annual production of 15,000 tons of biomass pellets. According to the work system, it can be calculated that the output of this biomass pelleting plant project is 6-7t/h, 50t/d, 1250t/m.
• Labor capacity: 25 people, 20 of whom live in the biomass pellet plant and 5 live in the biomass pelletizing plant.
• Working system: 300 days of work per year, 8-hour workday, single-shift system.

Main raw material consumption 

The 50t/d biomass pelleting plant project makes full use of the surrounding enterprises to produce scrap wood scrap powder, straw powder and lignin powder to process into biomass pellets fuel. Biomass pellets: It is a cold compact molding process for crushed biomass, forestry waste and other raw materials under normal temperature conditions using a pressure roller and a ring die from biomass pellet making machine.

The density of raw materials is generally 0.1-0.13t/m³, and the pellet density after molding is 1.1-1.3t/m³, which is convenient for storage and transportation, and greatly improves the combustion performance of biomass.

Main biomass wood pellet manufacturing machines 

Biomass pellet plant procedure for bio fuel pellets from wood straw bamboo powder

Wooden scrap powder, straw powder and lignin powder are mixed and dried and fed into the feed bin, and then transported by a screw conveyor into a biofuel pellets machine for compression and granulation. Finally, the finished pellets are packed in packaging bags and put into storage.

1. Drying section——biomass pelletizing plant:

   After entering the factory, raw wood scrap powder, straw powder, lignin powder, etc. will be dried using a 4t/h biomass test boiler to provide steam;

2. Feeding section——biomass pelletizing plant:

   Mix the purchased raw material wood scrap powder, straw powder and lignin powder into the feeding bin;

   

3. Granulation section——biomass pelletizing plant:

   The mixed raw materials are sent to the biomass pellet mill machine through the screw conveyor, and the finished product is made by extrusion.

   The biomass pellet making machine extrusion process is a physical process, no adhesive is added, and no chemical reaction occurs. The connection of the auger, the outlet and the outside, the biomass pellet making machine and the material conveying process are all sealed.

   

4. Packing section——biomass pelletizing plant:

   The products after being granulated by the biomass pellet machine are subpackaged, packaged and put into storage.
