Briquettes a (also known as white Coal) is an ideal fuel which substitutes coal, fire, wood lignite and other conventional fuels for heating steam generation. The demand of white coal has emerged from the shortage of conventional fuels like coal, oil, wood, etc. The shortage of this conventional fuel is increasing day by day; thus it indicates a golden future for alternative fuel.
Briquetting is a process of fuel manufacturing system from Agro wastes like groundnut shells, saw dust, mustard husk, cotton stalk et., In 100% groundnut shell briquettes, pulvarised is to be done which increases the production cost. The Machine which produce Briquettes is called Briquetting Machine.
Biomass Briquettes are made from the Agriculture Waste, Forestry Waste and Industrial Waste. It is been converted into solid cylindrical shape. The major residues which can be used are, Rice Husk, Coffee Husk, Coir Pitch, Jute Sticks, Sugarcane Baggasse, Groundnut Shell, Mustard Stalks, Cotton Stalks, Sawdust, Caster Seed Shells / Stalk, Wood Chips, Bamboo Dust, Tobacco Waste, Tea Waste, Paddy Straw, Wheat Straw, Sunflower Stalk, Palm Husk, Soyabean Husk, Veneer Residues, Barks & Straws, Forestry waste, Seeds Cases etc. Briquettes are only the bindings. Means it is made from residues and gives high calorific value cal/kg. The Technology that binds the wastage is called the Binder less Technology. It does not required any kind of Binder or Chemical / Adhesive. Many of the developing countries have now diversified to promote this technology, because it has low pollution and easy in use. Also in India it is very fast moving product, as States Government also are encouraging this Industry by giving incentives to the manufacturer, plant holder and Briquettes user. Briquettes are widely used for steam generation in boilers, heating purpose etc. As a fuel, Biomass Briquettes / White Coal are giving best results.
At present in Indian Territory it is being used in the Industries such as Paper Mills, Solvent Extraction Plants, Vegetable Plant, Chemical Plant, Textile Units, Dying House, Food Processing Units, Milk Plant, Sugarcane Mills, Leather Industries, Laminating Industries, etc. It shows that the Briquettes are very useful in each and every Industry which serves us every moment. In our regular life, the different product we use is made by using Briquettes as fuel. Government is giving 100 % text holiday up to 5 years.
