Public works

Water supply

The water consumption of this 6-6.5t/h straw pellet production line in Russia project is 2415m3/a. The water source of this project comes from the local municipal water supply network, which is mainly used as a water source for production, life and fire emergency, and can fully meet the requirements of this project.

Drainage

The drainage system of the factory area adopts a rainwater and sewage diversion system. Rainwater is discharged into the municipal engineering rainwater network nearby. This project does not generate production wastewater.

The wastewater is mainly domestic sewage of employees and canteen wastewater. The canteen wastewater generated by the project is pre-treated in the grease trap and discharged into the underground sewage treatment facility together with domestic sewage for treatment.

The treatment meets the "Comprehensive Sewage Discharge Standard" and finally enters the local river. The drainage volume of this project is 1932m3/a.

Power supply

The electricity used in this 6-6.5t/h straw pellet production line in Russia project is supplied by the local substation, which outputs 380V production power and 220V office and life electricity.

Fire protection

The fire protection design of the building of this project is based on the "Code for Fire Protection Design of Buildings".

Process design

The biomass pellet fuel of this 6-6.5t/h straw pellet production line in Russia project uses various crop straws, husks, etc. as raw materials. The production process consists of raw material crushing, granulation, cooling, etc. At the same time, each part is equipped with a strict quality monitoring system to ensure the quality of the product.

Process description:

1. Raw materials
   The raw materials of this 6-6.5t/h straw pellet production line in Russia project come from wheat straw, soybean straw, corn stalks, etc. in the surrounding rural areas. The purchased baled straw is transported to the factory area and temporarily stored in the raw material warehouse in the project area.
   The purchased bundled straw is sent to the workshop warehouse by loaders, forklifts, etc., and manually loaded and unloaded to the conveyor. The straw conveyor adopts a closed structure. Some raw materials with higher moisture content will be dried in the drying yard before use.
2. Crushing
   Wheat straw and corn stalks are crushed by a crusher. They can be granulated only after crushing. The raw materials after crushing are less than 5mm.
3. Pellet forming
   The biomass pellet fuel forming machine is a key equipment of the biomass pellet production line. The biomass fuel pellet machine can be used for different raw materials such as rice and wheat straw, sawdust, corn straw, bean straw, cotton straw and peanut shells, and the equipment runs stably.
   The density of the processed pellet fuel can reach 0.7-1.4 tons/cubic meter. The crushed material is sent to the elevator receiving hopper through a conveyor, and the material is sent to the feeder on the top of the straw pellet making machine through a bucket elevator. The feeder evenly sends the material to the pelletizer, and the surface of the pellets produced is smooth and the hardness is moderate.
   Friction between the material and the roller and the template in the pelletizer can generate a lot of heat, which can heat the material to about 80-110℃, soften the lignin, and sterilize it.
4. Cooling
   When the pelletizing and molding material is discharged, the temperature of the biomass pellet fuel is as high as 80-90℃, the structure is relatively loose, and it is easy to break. It must be cooled by the air cooling system and cooled to room temperature before it can be bagged and stored.
   It is sent to the cooler for cooling through the belt conveyor. The moving chain plate drives the particles to move. There is an air inlet at the bottom and a fan at the top. The cooling is completed after 2-3 minutes. The sealing process is completed inside the pellet machine. The pellet machine is closed and does not produce dust.
5. Packaging and storage
   This design uses a packaging conveyor for metering and belt packaging, and sends it to the finished product warehouse.

Rich Russian straw resources

Russia has abundant straw resources. ‌As a major agricultural country, Russia has vast arable land and abundant crop yields, which provides a solid foundation for the generation of straw resources. As a by-product of agricultural production, the amount of straw in Russia is considerable.

Straw pellet fuel uses solid waste such as corn stalks, wheat straw, rice straw, peanut shells, corn cobs, cotton stalks, soybean stalks, weeds, branches, leaves, sawdust, bark, tea seed shells, etc. as raw materials. After crushing, pressurization, densification, and molding, it becomes a modern clean fuel in the shape of small stick-shaped solid particles. It is also an emerging special fuel for biomass power generation, which can replace traditional coal.

Russia has abundant straw resources mainly for the following reasons:

• Vast arable land‌: Russia has vast arable land, especially large planting areas of major crops such as wheat, corn and soybeans, which have high straw yields.
• Large agricultural output‌: Russia has a large agricultural production volume, especially the annual output of crops such as wheat and corn, which makes straw resources very rich.
• Climate conditions‌: Most parts of Russia have a cold climate and long winters, which are conducive to the growth of crops and the production of straw.

Russia's use of straw resources mainly includes:

• Straw return to the field‌: Russia uses the method of returning straw to the field, returning straw directly to the farmland, increasing the organic matter content of the soil and improving soil fertility.
• Feed use‌: Straw can be used as feed for livestock, especially in winter and spring. As an important feed resource, straw plays an important supporting role in animal husbandry.
• Energy utilization: In some cases, Russia also uses straw as energy. Although this method is less common internationally, in some areas of Russia, straw is used as biomass energy.

Prospects for building straw pellet production lines in Russia

The prospects for starting straw pellet production line in Russia are generally positive. Russia has abundant forest resources, which provides a guarantee for the supply of raw materials for straw pellet fuel.

In addition, the Russian government has supported the straw pellet industry and promoted the development of the industry by issuing policy documents and establishing special management agencies. These factors work together to make the Russian straw pellet fuel market have broad development prospects.

Specifically, the development of the Russian straw pellet fuel market is affected by the following key factors:

• Market demand: Although the domestic demand for straw pellet fuel in Russia is relatively low, the export market is broad, especially the European market. 90% of Russia's straw pellet fuel is exported, mainly to European countries.
• Government support: The Russian government supports the production and export of straw pellet fuel by subsidizing export transportation and providing preferential loans. These measures help increase production and reduce the accumulation of domestic wood waste.
• Production costs: Russia has abundant forest resources and low raw material costs, which helps reduce production costs and improve the market competitiveness of products.
• Technical challenges: Although Russia's straw pellet fuel production shows a trend of sustained growth, there is a lack of efficient combustion technology in the country, and the existing municipal boiler room needs to be modernized.
• Impact of international sanctions: Affected by international sanctions, Russia's wood pellet plants face challenges in equipment maintenance and logistics costs. The loss of the EU market makes exports difficult.

In summary, despite some challenges, the strong support of the Russian government and abundant resource conditions provide a good foundation for starting straw pellet production line in Russia. By overcoming technical barriers and adapting to changes in the international market, Russia's straw pellet fuel processing industry is expected to achieve stable development.
