The Low heating value, reaction time, burning temperature and gas emission of jatropha seed cake respectively from whole, kernel and crushed seeds preheated at 25°, 50°, 75° and 100°C temperature and under 8400, 15000 and 19500 pounds pressure levels were assessed. At this effect, the combustion process consisted in introducing 20 g of each cake sample type into a one liter volume burning chamber and 130 g of water also into one liter water compartment of a designed combustion unit. The main results were as follow. The highest lower Heating value (21,51±93,64 MJ/kg) was obtained with the cake from crushed seeds preheated at 100°C and under of 15000 pounds pressure. The highest reaction time (1072,66±153,44 seconds) was registered with cake from kernel seeds also preheated at 100°C but with 19500 pounds pressure. The highest burning temperature was recorded from the whole jatropha seed cake. The highest carbon monoxide level ( ) was recorded during crushed and whole seeds cake combustion while the carbon dioxide level was the highest with the kernel seed cake.
