The Briquetting Concept...
The process of " BRIQUETTING " is the physical transformation of the loose raw material into high density fuel briquettes through a compactly compressed unit. The form change results in a much higher specific density of the material which increases its combustion efficiency as compressed to the loose material. Energy is the key factor in economic development of the country. By the turn of the century our requirement of energy will increase rapidly. it is expected that approximately 450 million tons of coal, 80 million tons of crude oil and 150 tons of fire wood will be required at that time to meet the domestic demand. It is unlikely that we can meet the requirement of fire wood or coal if we have to stop the already deteriorating ecology. Results of fossil fuels are also limited, which has resulted in the universal recognition of the need to tap energy from non-conventional sources. The Agricultural and Forest Wastes and Residue can be converted into fuel briquettes i.e. " BIO COAL" and is fairly a good substitute for coal, lignite, firewood, crude oil .This recycled fuel  is beneficial for the environment as it conserves natural resources. What many people do not know is that recycling also prevents global warming which has a direct adverse impact on global climate.

What can be briquetted ...
Almost any biomass can be briquetted. Every year millions of tons of agricultural wastes are generated which are either destroyed or burnt inefficiently in loose form causing air pollution. These wastes can can be recycled & can provide a renewable source of energy by converting biomass waste into high density - fuel briquettes.

AGRO WASTE:- Mustard waste, Rice husk, Arhar stalks, Groundnut Shell, Pine needles Sarkanda, Bagasse. Coffee husk, Cotton Stalks, Sunflower & waste, Sugarcane bagasse, leaves & trash, maize stalks, bajra cobs. Coir dust.

FOREST WASTE:- Wood chips and shravings, Tree bark and twings, Saw dust bamboo leaves. Wild grasses. Shrubs
Above raw material can be briquetted without using any binder. After making Briquettes from above materials it contains calorific value of 3500-4800 k.cal/kg.

 

Biomass Briquettes - the cheapest fuel...
Briquettes produced from briquetting of biomass are fairly good substitute for coal, lignite, firewood and offer numerous advantages:-

• Briquettes are cheaper than COAL, OIL or LIGNITE once used cannot be replaced.

• There is no sulfur in briquettes.

• Biomass briquettes have a higher practical thermal value and much lower ash content (2-10% as compared to 20-40 % in coal).

• There is no fly ash when burning briquettes.

• Briquettes have a consistent quality, have high burning efficiency, are ideally sized for complete combustion.

• Combustion is more uniform compared to coal and boiler response to changes in steam requirements is faster due to higher quantity of volatile matter in briquettes.

• Unlike coal, lignite or oil, briquettes are produced from renewable source of energy, biomass.

• Briquettes have high specific density (1200 kg/m3) compared to 60 to 180 kg/m3 of loose biomass.

• Loading/unloading and transportation costs are much less and storage requirement is drastically reduced.

• Briquettes are clean to handle and can be packed in bags for ease of handling and storage.

• Briquettes are usually produced near the consumption centers and supplies do not depend on erratic transport from long distances.
