Bio coal is a solid form of bio energy. Biomass (Agricultural waste) is compressed under high pressure to
produce bio coal briquettes are a non conventional source of energy.
With heating capacity ranging from 3500‐4750kcal, bio coal can serve as a substitute to black coal in
industrial boilers and brick kiln for thermal application.
Briquettes have high specific density (1200 Kg/m3) and bulk density (800 Kg/m3) compared to 60 to 180 Kg/m3 of loose bio coal.
Compared to fire wood or loose biomass, briquettes give much higher boiler efficiency because of low moisture and higher density to max 300 mm.
Bio coal Briquettes are of sizes diameter 60mm to 90mm and length min 75 to max 300 mm.
Comparison with Coal
- Briquettes provide higher thermal value than coal when used for firing industrial boilers.
- Moisture content in coal is inconsistent and on the higher side as compared to white coal.
- Biomass briquettes on average saves 30–40% of boiler fuel cost.
- There is no sulphur or fly ash generated when briquettes are burned.
- Bio Coal briquettes have consistent quality and size which is ideal for complete combustion.
- Combustion is more uniform as compared to coal. Due to high quality of volatile matter, boiler response to volatile matter is faster.
- Raw materials can be produced domestically in India, creating a fuel source that is free from foreign dependence and less polluting than raw fossil fuel incineration.
- Environmentally, the use of biomass briquettes produces much fewer greenhouse gases, specifically, 13.8% to 41.7% CO2 and NOX.
- Biomass briquettes are also fairly resistant to water degradation, an improvement over the
difficulties encountered with the burning of wet coal.
