Briquetting is the process of processing of a material into briquettes- A piece having a uniform, geometric shape and practically identical weight. The briquette name comes from French language. It means brick. In earlier the briquette has a large in shape and they could be shacked. The briquette has lower ash sulfur content. Briquettes have high specific density and bulk density compared to loose bio mass. The briquettes are cheaper than a coal. Briquetting equipment is used in various industries as it is non-polluting with high calorific value.
Briquetting was proposed in Russia in the 1830’s by the Russian inventor F. P. Veshniakov, who developed a method of producing hard briquettes from waste wood charcoal and hard coal. Briquetting creates additional fuel resources from fine materials, primarily fuels and ores, the use of which would otherwise be inefficient or difficult; it also makes it possible to use waste products, such as dust, slags, and metal chips. In all cases, the usefulness of briquetting is judged by economic factors. Depending on the material to be processed, briquetting may be done with binders at medium pressures. In order to produce briquettes of high quality, the material used must meet specific requirements for fractional composition, moisture content, temperature, and the like.
No one can refuse from the fact that pollution increase due to excessive use of fossil fuels like petrol, diesel and black coal. These are a traditional source of energy and it increase pollution in the air. So briquetting are eco-friendly source of renewable energy as it does not spread pollution in the air and economical than black coal. In our daily life thousand tons of waste and organic material release but we do not know how to use it efficiently and we either burnt it or destroy it so briquetting is the revolutionary idea. They are economical than black coal and contains low ash. Loose biomass like waste have low density so we cannot move it from one place to another place but briquettes have high density and they are also easy to pack and store.
