Bio-coals are coal-biomass briquettes and are used as seamless substitute for coal in process heating and power generation applications. The high heating values of Jatropha press cake residues provides a very promising pair with coal for such applications. The study investigated the combustion properties, performance and net energy balance of various (100%, 50%, 20%) carbonized Jatropha-coal and plain Jatropha coal briquette blends. Heating value, proximate analysis and combustion efficiency of each blends were tested. A fuel cycle based energy accounting to determine the net energy and fossil energy requirement of each was implemented. Results showed that both carbonized and non-carbonized briquettes and 50% carbonized Jatropha and coal blends provided net energy production higher than coal. Despite having greater fuel preparation energy requirement, all of the briquette blends tested provided lower fule cycle fossil energy consumption. The findings validate the potential of Jatropha bio-coals as possible substitute for coals in industrial applications.
