Biomass pellet machine is a kind of biomass energy pretreatment equipment. It mainly uses biomass such as wood chips, straw, rice husks, bark and other wastes from agricultural and forestry processing as raw materials, and solidifies it into high-density pellet fuel through pretreatment and processing. Biomass pellet machine is divided into flat mold biomass pellet machine and ring mold biomass pellet machine.

Intro

Biomass pellet machine is a kind of biomass energy pretreatment equipment. It mainly uses biomass such as wood chips, straw, rice husks, bark and other wastes from agricultural and forestry processing as raw materials, and solidifies it into high-density pellet fuel through pretreatment and processing. Biomass pellet machine is divided into flat mold biomass pellet machine and ring mold biomass pellet machine

Advantage

With the combined treatment of energy and environment in China, straw fuel (that is, biofuel) is the use of solid waste such as corn stalk, wheatgrass, straw, peanut shell, corn cob, cotton stalk, soybean stalk, weed, branches, leaves, sawdust, bark and other crops as raw materials, which is crushed, pressurized, densified and formed into small rod-like solid particle fuel. Pellet fuel is made by pressing wood chips, straw and other raw materials with roller and ring die under normal temperature. The density of raw materials is generally about 0.6-0.8, and the particle density after molding is greater than 1.1, which is extremely convenient for transportation and storage. At the same time, its combustion performance is greatly improved, reducing human dependence on petrochemical energy and atmospheric emissions.

Rational utilization

Biomass fuel is the use of crops of corn stalk, wheatgrass, straw, peanut shell, corn cob, cotton stalk, soybean stalk, rice husk, weeds, branches, leaves, sawdust, bark and other solid waste as raw materials, after crushing, pressurizing, densification, molding, into a small rod-like solid particle fuel. Pellet fuel is made by pressing wood chips, straw and other raw materials with roller and ring die under normal temperature. The density of raw materials is generally about 0.6-0.8, and the particle density after forming is greater than 1.1, which is extremely convenient for transportation and storage. At the same time, its combustion performance is greatly improved, which brings certain employment problems and economic benefits.

Process flow

Collection of agricultural and forestry raw materials → crushing of raw materials → drying of raw materials → granulation molding → cooling → screening → bagging

Fuel characteristics

Characteristics of biofuels; The pellet fuel after molding is heavy, small in size, resistant to combustion, and easy to store and transport. The density after molding is 1.1-1.5. The calorific value can reach 3400~4800 kcal. It is a high volatile solid fuel with low sulfur content.

Fuel use

The pellet fuel after molding is a new type of bioenergy, it can replace wood, coal, oil, liquefied gas, etc., widely used in heating, living stoves, hot water boilers, industrial boilers, biomass power plants and so on.

Main use

1. Domestic heating and living energy: high fuel utilization rate, easy storage;

2. Biomass industrial boilers: as the main fuel of industrial boilers, replacing coal and reducing atmospheric emissions and pollution;

3. Power generation: can be used as fuel for thermal power generation.
