Calorific values of briquette
The calorific value of biomass briquettes typically ranges from 3,500 to 4,500 Kcal/kg, depending on the type of raw material used, moisture content, and briquetting process. Briquettes made from materials such as sawdust, groundnut shells, and wood waste generally provide higher heat output and consistent combustion performance.
Due to their high energy density, low moisture content, and efficient burning characteristics, biomass briquettes are widely used as an economical and eco-friendly alternative to coal and other conventional fuels in boilers, furnaces, and industrial heating applications.

Biomass materials and industrial residues are important renewable energy sources. They can be converted into briquettes and used as alternative fuels for power generation. Since the properties of biomass, such as calorific value and ash content, vary by material and region, the values provided are for general guidance only.

Intrinsically incubate intuitive opportunities and real-time potentialities. Appropriately communicate one-to-one technology after plug-and-play networks.Biomass briquettes can be used along with fossil fuels such as coal, lignite, and pet coke in boilers and furnaces. Co-firing briquettes with fossil fuels helps industries reduce fuel costs, lower carbon emissions, and improve sustainability without major modifications to existing systems.
