Biomass Briquette

Briquettes are manufactured from various types of Biomass (agricultural residues) available in nature. Loose biomass is compressed to form 90 or 60 mm cylindrical blocks which are used as fuel. Use of easily available agro residues for briquetting, makes this fuel as a cheap alternative for liquid and gaseous fossil fuel.

Advantages of Biomass Briquettes:

  • Cheaper alternative for fossil fuel.
  • Do not disturb Environmental Carbon Cycle.
  • No Sulphur content in the biomass hence No Sulphur dioxides pollution.
  • Due to nill Sulphur dioxide, corrosion of equipment is less.
  • Biomass used in Briquettes includes Bagasse, Saw dust, Ground nut shell, Coffee husk, Soybean husk, Cotton stalk, Coconut Shell, Gram husk etc.

Composition of Briquette

  • Carbon (%) - 47
  • Ash (%) - up to 15
  • H2 (%) - 6.4
  • Moisture (%) - less than 5%
  • Sulphur (%) - 0
  • Other traces (%) - 45
  • GCV (Kcal/kg) - 3500 to 4200*

Availability: With proper Supply Chain Management briquettes are easily available throughout the year. High density due to compression allows transportation of briquettes at long distances.
