Reasonable layout

The project is adjacent to a temporary garbage storage point on the north side. The overall layout of the plant is “L” shaped. The area on the north side of the plant is reserved for employee living areas.

The raw material storage area, production workshop, warehouse, and living area are all located in the south side of the site. From west to east, they are arranged as raw material storage area, reserved factory building, production workshop, warehouse, and living area.

• The west side of the project is a ravine.
• The raw material storage area is located at the westernmost side of the south side of the site, far away from the living area, which reduces the incidence of accidental fire accidents and is easy to control after an accident occurs.
• The living area is located at the easternmost side of the south side of the site, in the crosswind direction of the production workshop, reducing the impact of production dust on the living area.
• There are 2 fire water pools in the site, one on the southeast side and one on the northwest side, which can prevent accidents in time.
• The distance between the workshops and the reserved roads on the north and south sides meet the requirements of fire protection distance and sanitary protection, and meet the width requirements for raw materials and finished products entering and leaving the factory.

Therefore, the layout of this project is very reasonable.

Process flow

The construction process of this project can be divided into four stages: preliminary preparation, construction, completion acceptance and completion operation. The construction stage of the project mainly includes the demolition of the original buildings in the factory area, site leveling, foundation engineering, main engineering, site hardening and equipment installation.

This project is a biomass pellet fuel construction project. The main process flow during the project operation period is:

1. Put the raw materials in the yard, such as sawdust, straw, etc., into the crusher for crushing, screen and mix, and then enter the crusher for crushing.
2. After that, the raw materials are transported to the fully enclosed drum dryer, and the hot flue gas of the biomass hot air furnace is introduced into the induced draft fan for drying.
3. The induced draft fan introduces all the sawdust and hot flue gas in the drum dryer into the drying moisture separator. The dryer end facility of this project is processed by the drying moisture separator.
4. The dried sawdust is discharged from the drying silo discharge port and sent to the pelletizer, and finally enters the separator to separate the dust and package the finished product.

The drying products of this project use hot air furnaces burning biomass materials. The general characteristics of biomass fuels are high moisture, low ash, high volatile matter, low calorific value, and irregular shape.

At present, the combustion devices developed for the characteristics of biomass fuels are: biomass fuel layered combustion device, biomass fuel fluidized bed combustion device, and biomass fuel diffusion combustion device. In order to meet the requirements of grain drying and ensure good performance, the following general principles should be followed when designing straw burning furnaces:

Simple structure, easy to manufacture, low cost; less labor required, easy operation and maintenance; complete combustion, good flue gas quality, high thermal efficiency; taking into account various uses other than drying and the adaptability of different fuels. The combustion quality depends on the following factors: furnace temperature, combustion time, turbulence and mixing degree in the furnace, air-fuel ratio, and the physical properties of the fuel itself.

Recommended values ​​of main design parameters:

Grate area: 70 pounds of fuel/square foot (70bf/in2-6894.76Pa); furnace volume: 10×grate area; theoretical air volume for corn straw combustion: 505kg air/kg fuel dry weight; excess air coefficient is greater than 0.5, and the optimal value is 1~4.

Some design experience: When the moisture content of the straw is high, the feed rate cannot be too large; if the feed is too much, it cannot be dehydrated, volatilized and burned in time, which will cause incomplete combustion.

The inner wall of the furnace should be made of a material with high reflectivity so that the radiant heat energy reached can be emitted back to the center of the flame to promote combustion.

When the furnace temperature is higher than 800℃, the slag produced after the fuel combustion will melt back, and after melting, it is easy to adhere to the grate, block the ventilation holes, and worsen the combustion condition.

To avoid the above situation, the temperature of the slag before discharge should be controlled below 800℃; the air intake should be sufficient to ensure complete combustion on the one hand and avoid slag melting on the other hand; when possible, it is best to process the fuel, such as flattening and chopping, to expand the contact area between air and fuel and make combustion faster.

Biomass energy is the use of biomass to produce energy. Currently, biomass used as energy is mainly crop straw, forestry and wood processing waste. With the continuous development of my country’s economy, the problem of energy shortage has become increasingly prominent.

Since biomass energy has the significant characteristics of being pollution-free and renewable, the development and utilization of biomass energy is particularly important. In this context, the client of this project, an investor from New Zealand, uses the existing factory building to build a project with an annual output of 20,000 tons of biomass pellets.

The labor quota is 5 people, none of whom are boarded and lodged in the factory area. Work 300 days a year and 8 hours a day.

Process flow

The raw materials of this complete wood pellet plant project are waste firewood, forestry residues, furniture factory scraps, straw, and sawdust. The moisture content of the raw materials will be controlled during the purchase.

1. Chipping: After the raw materials enter the site, they are stored in the raw material warehouse. The loader is used to move the waste firewood, wood veneer, thin branches, and furniture factory scraps to the conveyor belt, and then sent to the chipper through the closed belt to be crushed into small pieces of wood. The crushed wood blocks enter the closed material transfer room with the conveyor belt.
2. Crushing: Use a loader to move the crushed wood blocks, straw, and sawdust to the conveyor belt and send them to the crusher for crushing. The crushed materials enter the closed material transfer room through the conveyor belt.
3. Granulation: Use a loader to add the materials to the auger screw conveyor, and send them to the pelletizer through the conveyor, and press them into shape in the pelletizer. During the extrusion process, the friction between the machine and the biomass raw materials will generate heat, which softens the lignin contained in the raw materials and acts as a binder.
4. Cooling: The formed materials are transported to the finished product warehouse via a conveyor belt for natural cooling. The cooled finished products are packaged according to customer needs, and unqualified products can be returned to production as raw materials.

This is a Thai wood pellet project with an annual output of 30,000 tons. The total investment of the project is US$580,000, covering an area of 5,000 square meters and a construction area of 5,000 square meters.

1. Chipping: The raw materials are transported to the raw material warehouse of the project site by car for stacking. The raw materials are sent to the chipper crusher by a wood grabber for preliminary crushing into smaller block materials.
2. Crushing: The crushed block materials are sent to the hammer mill crusher by a conveyor for crushing. The particle size after crushing is not more than 7mm.
3. Granulation: The crushed materials are transported to the pellet machine and formed into finished products by extrusion. The extrusion process is a physical process. No adhesive is added and no chemical reaction occurs. Except for the connection of the feeding auger and the feed and discharge ports, they are all sealed.
4. Packaging and storage: The formed biomass pellets are packaged and stored in the finished product warehouse for sale.
