A cofiring tests of coal and jatropha press cake, combustion test of coal and combustion test of jatropha press cake has been carried out using a bubbling fluidized bed combustion system at the Energy and Chemicals Division of Industrial Technology Development Institute, DOST in Bicutan, Taguig, Metro Manila. Combustion of coal and jatropha press cake was performed to compare the performance of coal-jatropha press cake cofiring. Coal and Jatropha press cake were blended in the ratio 70:30 respectively for cofiring test. The fuel was fed through a variable speed motor screw feeder into the reactor at two different air flow rates and three different feed rates. The fluidizing medium was sand and the temperatures for each feedstock were monitored and recorded throughout the experiment. For each of the test performed, a flue gas analysis was taken with a Kane-May combustion analyzer. The coal-jatropha press cake cofiring efficiency was determined from the test, resulting to a high 65% at 34 m3/hr air flow rate and 8.1 kg/hr feedrate. The cofiring test then demonstrated that jatropha press cake could be co-fired with coal in a fluidized bed combustor.
