Biomass briquettes are made of various sorts of raw material like bagasse, sawdust, coffee shells, groundnut shells, etc. Biomass with defined specification can be used as raw material for manufacturing briquettes. Kenya being an agricultural country, every year millions of tons of agricultural waste are generated. These are either not used or burnt inefficiently in their loose form causing air pollution due to lack of technology. Briquettes have high specific density (1200kg/m3) and bulk density (800kg/m3) compared to 60 to 180kg/m3 density of loose biomass.
Types of Briquettes
There are generally two types of briquettes; carbonized and non-carbonized. The most often-ly used briquette for industrial purpose are the non-carbonized.
The briquette specifications are as outlined below.
- Briquette diameter 90mm.
- Lower ash content less than 5%.
- Moisture content less than 10%.
- Compressive strength
- Contains high density & higher fix carbon value.
- Thermal calorific value approx. 4200Kcal/Kg.
- Highly Economic compared to fossil fuels.
- Consistent high burning efficiency.
- Easy for transportation, feeding & combustion.
- Feedstock – 100% saw dust
- Uniform combustion.
- Pollution free & non-hazardous.
- Eco friendly & Renewable Energy fuel.
