All About Biomass Briquetting | Ecostan

 Let’s start the blog with the history; basically, the British mechanical engineering research institute first developed the Briquette with the usage of fertilizer raw material. After that, the technology was utilized to clean coal and progressively developed to utilize the raw material in the paper mills. In the year 1930, the screw-type biomass briquette machine was first designed by the United States. Simultaneously, in Germany and Sweden, modern piston briquetting machines were promoted and invented. In 1950, the screw-type briquetting machine was built in Japan. But in the decade of the ’80s, biomass briquetting technology was produced on a large scale. Let’s read more about biomass briquette.

 

Principle Of Biomass Briquetting:

The biomass material density and structure are relatively small and lost respectively, which is determined by the physiological characteristics of the plant. The loose biomass stuff, when subjected to a certain outside pressure, will increase the density and decrease the volume. The waste material particles go through consecutive stages of mechanical deformation, plastic rheology, and rearranging position. Generally, the cellulose can be shaped into a definite form with a small force in the presence of moisture.

 

In general, it is impossible to restore the original shape and it becomes a firm structure briquette when the water content is about 10%, however, it is essential to put on a big pressure to make it, because the viscoelastic or non-elastic fiber molecules are twisted and entangled together, after eliminating the outside pressure. Take the lignin as an example, plastic deformation occurs when the briquetting temperature reaches its softening point, thus bonding the raw fibers narrowly composed and preserving the established shape.

 

The strength of the shaped briquette is increased after cooling; thus we get a biomass briquette that is alike to wood burning performance. It is necessary to include a suitable proportion of binders, such as starch, waste paper, clay, and many more when the lignin content of the raw material is low, to form the briquette with a fixed shape and dense structure. There will be an adsorption layer on the surface of the biological particles after adding the binder, which will cause a gravitational force among the particles. the particles can also generate an electrostatic attraction between the particles when the external force is applied, consequential in particles a chain structure.

 

The Biomass Briquetting Process And Equipment:

In biomass briquetting, the most important process is biomass collection. In the briquette plant, biomass requires to be concentrated. There are two problems to be considered: the briquetting plant’s service radius, and the moisture of the raw biomass. The moisture should be lower if it is not harvested by machinery. Furthermore, focus on the entrainment of soil during the collection procedure. Crushing, drying, briquetting, heating, binding, and shape retention are some essential steps for biomass briquetting.
