Thermal destruction is one of the most effective processes to treat organic waste in view of the volume reduction. However, some pollutant emissions associated with waste incineration have led to reluctance to apply this state-of art technology. 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. Better understanding the mechanism of combustion in an incinerator will help the design of more efficient combustion devices. The objective of this research is to investigate the key operating parameters related to the performance of an incinerator using a heterogeneous laboratory scale spouted bed combustor. The spouted bed is considered as an innovative type of fluidized bed and provided with a small centrally located inlet aperture in its conical base which allows a jet of fluid to enter. The ability to use low heat value fuels due to heat recirculation inside the bed and low pollutants emission levels brought down by the long residence time stimulate the application of this combustor in laboratory research. Formation and destruction of the aromatic products of incomplete combustion (PICs) in the post-combustion region for burning toluene and PVC (polyvinyl chloride) is under investigation in this study. The residual hydrocarbons and chlorinated hydrocarbons species are measured. The primary compounds including aromatics, substituted aromatics, and polycyclic aromatics hydrocarbons (PAHs) are formed and destroyed during flue gas passing through the low temperature region. The flue gas samples are induced from the side probes along the reactor with constant flow rate and simultaneously to monitor the temperature by using thermocouples. The sampling train consists of a fiber glass filter and an impinger.
