Thermal destruction is one of the most effective processes to treat organic waste in view of the mass and volume reduction. Proper control of the incineration process with respect to operating parameters to produce flue gases acceptable to the environment is essential for the success of this approach. Some products of incomplete combustion (PICs), due to their specific toxicological potential, may represent a risk for the human health. A laboratory scale spouted bed reactor is employed to simulate the chlorinated organic compound combustion in this research. Those hydrodynamic phenomena in the spouted bed and reaction kinetic parameters will affect directly and/or indirectly to PICs formation. Toluene was chosen as the auxiliary fuel mixed with chlorophenols for combustion. Based on the experimental results suggested that chlorine contents could lead to inhibit the complete combustion and the size of bed medium could modify the heat transfer in a spouted bed reactor.
