What you need to know about Biomass Pellet Machinery 2022

Biomass pellet machinery is a kind of biomass energy pretreatment equipment. It mainly uses biomass such as wood chips, straws, rice husks, and bark from agricultural and forestry processing wastes as raw materials, which are solidified and formed into high-density pellet fuels through pretreatment and processing.

1, Introduction to Biomass Pellet Machinery

The biomass granulator is divided into two types: horizontal and vertical, both of which use ring die, but have different structures. Using biomass such as wood chips, straw, rice husk, and bark in agricultural and forestry processing waste as raw materials, after pretreatment, it is solidified into high-density pellet fuel.

2, Advantages of Biomass Pellet Machinery

Countries around the world are carrying out coordinated governance and management of energy and the environment to varying degrees. Straw fuel (that is, biofuel) is based on the solid waste of crops such as corn stalk, wheat straw, straw, peanut shells, corn cobs, cotton stalks, soybean stalks, weeds, branches, leaves, sawdust, bark, etc. , pressurized, densified and shaped by biomass pellet machinery, eventually becoming solid biomass pellet fuel.

Pellet fuel is made by extruding wood chips, straw and other raw materials through pressing rollers and ring die under normal temperature conditions. The density of raw materials is generally around 0.6-0.8, and the density of formed particles is greater than 1.1, which is very convenient for transportation and storage. At the same time, its combustion performance is greatly improved, reducing human dependence on petrochemical energy and atmospheric emissions.

4, Characteristics of Biomass Pellet Fuel

The characteristics of biofuels; the formed pellet fuel has a large specific gravity, a small volume, and is resistant to combustion, which is convenient for storage and transportation. The density after molding is 1.1-1.5. The calorific value can reach 3400~4800 kcal. It is a solid fuel with high volatile content and low sulfur content.

5, The Performance Index of Biomass Pellets

  • Density >1.1-1.5t/m3
  • Appearance Light yellow cylindrical φ6-10mm
  • Ash content ≤2%
  • Moisture ≤7-10%
  • Combustion rate ≥98%
  • Thermal efficiency ≥81%
  • Smoke blackness (Lingemann grade) <1
  • Dust concentration ≤80mg/

6, Uses of biomass Pellet Fuel

The formed biomass pellet fuel is a new type of biomass energy, which can replace firewood, raw coal, fuel oil, liquefied gas, etc., and is widely used in heating, living stoves, hot water boilers, industrial boilers, biomass power plants, etc.
