Steam Dryer using a Mixture of Charcoal and Solid Biomass as a Fuel

The aim of this project is to scrutinize the effect of blend solid fuels consisting of charcoal, arecanut leaf and husk on calorific value. While arecanut leaf and husk are processed from natural plants. A significant increase in calorific value obtained when charcoal, arecanut leaf and husk with a proper ratio of mixing. To increase the availability of charcoal by using the solid bio waste like arecanut leaf and husk. It is easily available and the cost of this waste should be low compared to other fuel. It has high calorific value than other bio solid waste. It needs some preparation process before the combustion, which is mainly done for proper combustion. That fuels initially have the various size in nature, it is not effective for complete combustion so it will size before the combustion process. The ash content of the charcoal should higher than other fuel so the combination of these two fuel should give low ash and also cost. It is used in the application of steam dryer for drying cardamom and tea leaf.
