Biomass Briquettes are a biofuel alternative to Lignite-coal & Charcoal. They are made from agricultural waste and other organic materials, and are used in thermal applications. The biofuel is relatively clean burning when compared with the other fossil fuels used today. Biomass briquettes improve the volumetric calorific value and on average save 30-40% fuel cost. The Biomass briquettes are also known as White Coal/Bio Coal, they are used in various industrial applications like heating boilers.
Energy is the significant factor in economic growth of a country. With the conventional sources exhausting rapidly, there has been a surge of the use of Bio energy. Biomass briquettes are a promising bio fuel in the developing world. Due to lack of manufacturing and awareness it is still in the beginning stage in India. With calorific value of more than 3700 Kcal, the Bio Coal is a ready substitute.
Biomass briquetting is a process in which loose biomass material i.e. the agricultural waste undergo densification to produce compact composites with the use of pressure. The process does not include any binders or chemicals thus making it an eco-friendly fuel. It is a high-quality solid fuel suitable for many industrial and commercial applications that is easy to transport and store. It has similar features to ordinary coal with the vital improvements that it is clean, non-conventional, and renewable.
The specific density of biomass briquettes is as high as 1200 kg/m3 when compared to 60- 180 kg/m3 of loose biomass. When compared to wood or coal the biomass briquettes have low ash content as well as low moisture level. Some of the advantages of Biomass Briquettes are-
- Eco friendly & Renewable Energy fuel
- Economical and cheaper than other solid fuels
- Thermal calorific value approx. 3800 Kcal/Kg
- Pollution free & non-hazardous
- Lower ash contains 2% – 10%, there is no fly ash when burn
- Consistent high burning efficiency
- Contain high density & higher fix carbon value
- Easy for transportation, feeding & combustion
- Combustion is more uniform
