2.5T/H Bamboo Straw Wood Pellets Plant in Malaysia Project

Biomass mainly refers to crop straw, forestry and wood processing waste, etc. Biomass energy is an important renewable energy. Biomass can be converted into high-efficiency solid, liquid and gaseous fuels, which can be used to replace non-renewable energy sources such as coal, oil and natural gas.

Biomass pellet fuel has high volatile content, easy to precipitate, good carbon activity, flammability, less ash content, fast ignition, more fuel saving and lower use cost. The formed biomass particles are small in size, high in specific gravity, high in density, resistant to combustion, convenient for storage and transportation, and have a calorific value of 3900-4800 kcal. They are ideal new fuels and are widely used in domestic stoves and hot water boilers , industrial boilers and biomass power plants, etc.

In this context, in order to seize market opportunities, the Malaysia client of this project invested 300,000 US dollars to rent an idle plant to build a biomass pellet construction project with an annual output of 6,000 tons.

• The total land area of the project is 10,000m², and the total construction area is 6,400m², including production workshops (slicing area, crushing area, granulation area), drying workshop, finished product warehouse, raw material warehouse, living and office building, etc.
• The production scale is: 2.5 tons per hour, With an annual output of 6,000 tons of biomass pellets, it has been put into operation in April 2019.

It is worth mentioning that the client company is engaged in the production and sales of organic fertilizers. Because they are optimistic about the prospects of biomass pellets, they invested in the construction of this 2.5t/h bamboo straw wood pellets plant in Malaysia project.

Since the customer intends to expand the biomass pellet production line project in the future, RICHI engineers reserved at least 5t/h capacity when designing the process.

The total land area of the 2.5t/h bamboo straw wood pellets plant in Malaysia project is 10,000m², and the total construction area is 6,400m², including production workshops (slicing area, crushing area, and granulation area), drying workshops, finished product warehouses, raw material warehouses, living and office buildings, etc.

• Production workshop: Steel structure factory building with a construction area of 500m². (①Slicing area: mainly for cutting raw and auxiliary materials into flakes. ②Crushing area: mainly to crush the materials cut into flakes. ③Granulation area: the crushed material is granulated and shaped.)
• Drying workshop: a steel structure workshop with a construction area of 2500m², which is used to dry crushed materials;
• Raw material warehouse: used for stacking raw materials, steel structure workshop, construction area 500m²;
• 1# finished product warehouse: finished product warehouse, used to stack finished biomass pellets, steel structure workshop, construction area 1000m²;
• 2# finished product warehouse: spare finished product warehouse, used to stack finished biomass pellets, steel structure factory building, construction area 1000m²;
• Living and office space: 3F, used for living and office purposes, with a building area of 900m² and a brick-concrete structure.

Name	Annual usage	Source
Straw	3200t/a	Local purchase of crop straw
Scrap wood	2000t/a	Local lumber mill
Waste bamboo board	2000t/a	Local bamboo chip processing factory
Water	420t	Tap water
Electricity	100,000	Local grid supply
Biomass pellets	45t	Self-sufficient

Raw and auxiliary materials sawdust and waste wood are purchased from nearby wood processing factories and bamboo chip processing factories, and straw is purchased from local farmers.

• Slicing: The raw material waste wood is sent to the wood chipper by the conveyor belt, and the waste wood is cut into small pieces of 20mm*20mm by the wood chipper machine.
• Crushing: The cut wood chips are sent into the biomass pulverizer from the feeding hopper, impacted by the blade and the knife seat, the rotating knife and the fixed knife are sheared and pulverized at the same time, due to the action of the rotating centrifugal force, the material automatically flows out from the outlet.
  
  During the conveying process, the iron filings in the wood chips are magnetically separated and sent to the shredder.
• Drying: After the crushing is completed, determine whether to use drying according to the moisture content of the crushed raw materials. When the moisture content of the raw materials is relatively high, it needs to enter the drying furnace (the combustion method is heat storage type) for drying.
• Granulation: The crushed material is fed into the extrusion chamber of the biomass pellet mill by the feed hopper, and the crushed material is squeezed into the inner hole of the mold by the pressure roller, and is formed by hot extrusion of the mold.
  
  During the extrusion molding process, the material friction generate heat, about 40°C, the heat generated will dry the moisture in the material, and the extruded material will be cut into cylindrical particles at the outlet of the wood granulator. The whole process is physical extrusion without any bonding agent.
• Product packaging: Biomass particles enter the automatic packaging machine through the conveyor belt for packaging, and put them into storage for sale.

There are two sets of drying furnaces in this biomass pellet plant in Malaysia project, and each drying furnace is equipped with a cyclone dust collector. The drying furnace of this project uses the customer's own product (biomass fuel) as fuel. The annual raw material drying rate of the project is 6000t/a (after drying).

According to the technical data provided by RICHI engineers, the drying speed of each drying furnace is 2t/h, and the biomass fuel consumption is 15kg/h. After calculation, each drying furnace is used for 1,500 hours per year, with an average of 5 hours per day, and the two drying furnaces use 45 tons of biomass fuel per year.

01

Water supply

The water source of this 2.5t/h bamboo straw wood pellets plant in Malaysia project is tap water, and the total water consumption is 108m3/a.

02

Drainage

Based on 80% of the water consumption, the domestic sewage discharge of the project is 336t/a. The domestic sewage is treated by the septic tank set up in the factory area and used for fertilization of the surrounding farmland.

03

Power supply

The project electricity is supplied by the local power grid. .

04

Labor quota

There are 10 project workers, and the project provides board and lodging. Working 300 days a year, 8 hours a day, one shift.

05

Construction schedule

The construction period of this project is 3 months, from February 2019 to April 2019.

According to factors such as project terrain, external natural conditions, and access roads, the overall layout pattern is as follows: the gate of the factory area is located in the east of the factory area; the east of the factory area is arranged as an office building and parking lot; Drying area and raw material storage yard.

The layout of the 2.5t/h bamboo straw wood pellets plant area can meet the requirements of the production process, and it is continuous, short and convenient. The layout of the buildings complies with fire protection, sanitation regulations and various safety regulations and requirements, and appropriate greening is arranged on both sides of the road and around the buildings.
