The Developed system is designed to produce the charcoal from biomass samples like Jatropha seed husk, Melia Dubia and Prosopis juliflora. The technology adopted is hybrid by combining both direct and indirect method of heating the biomass based on pyrolysis. The temperature is in the range of 300°C to 500°C. In results of the proximate analysis showed the fixed carbon content is increased in this pyrolysis unit charcoal whereas biomass sample and existing pyrolysis unit charcoal showed lower fixed carbon content. The charcoal yield efficiency is 34.84% whereas in conventional method of charcoal making the charcoal yield efficiency is about 20%. The mass and energy closure were found to be 72.72% and 80.30%.
Pyrolysis unit is first of its kind in using semi in direct heating method
Creating an economic value and local opportunity to create and use charcoal as charcoal yield is 34% which is higher than conventional method (20%)
Charcoal was produced with the use of biomass displaces fuel oil and natural gas in domestic heating applications
It promotes distributed local agriculture productivity and energy production
Pyrolysis, charcoal production, charcoal yield efficiency, mass balance, energy balance
