On what basis do briquettes types distinguish?
Briquettes are an environmentally friendly fuel, and the types can be distinguished according to many factors. The following are several common classification methods:
(What are the requirements of biomass briquetting machine for raw materials?)
1. Source of raw materials
The types of briquettes can be distinguished according to the source of their raw materials. Common raw materials include:
Sawdust: it is made of sawdust or waste wood from the sawmill.
Crop residues: such as rice husk, corn stalk, peanut shell, etc. Biomass mixture: a compressed material made by mixing a variety of biomass.
2. Shape and size
The shape and size of compressed briquettes are also important basis for differentiation. Common shapes include:
Cylinder shape
Square shape
Hexagon
The selection of these shapes and sizes is usually designed according to the requirements of combustion equipment.
3. Production technology
Production process will also affect the classification of briquettes. For example:
High-pressure forming: raw materials are pressed and formed by high-pressure equipment.
Adding adhesive: adding natural or chemical adhesive to raw materials to enhance the molding effect.
Non-adhesive technology: only through high temperature and high pressure, the natural cellulose in raw materials can be bonded.
4.Uses
According to the use, compressed briquettes can be divided into:
Household heating: usually suitable for fireplaces or household stoves.
Industrial fuel: used in industrial boilers, power plants, etc.
Barbecue: specially designed for outdoor barbecue, with less smoke when burning.
5. Calorific value and ash content
(What is the calorific value of biomass fuel related to?)
Different kinds of compressed briquettes have different calorific value (energy generated by combustion) and ash content because of different raw materials and processes. Products with high calorific value and low ash content are usually more popular in the market.
In a word, the classification of compressed briquettes mainly depends on raw materials, shapes, production technology, uses, combustion performance and other factors. Consumers can choose suitable products according to their own needs to achieve the best use effect.
