Experimental Approach to Premixed Gas Combustion in a Packed Bed : Investigations of CO Emission

Abstract

CO emission of the gas phase combustion in a packed bed has been investigated experimentally and numerically for lean methane/air premixed mixture. The results show that CO emission is generated at the bed temperature just lower than the temperature in which combustion is completed. This CO emission is due to the early stages of combustion reactions, which does not only depend on the bed temperature but on a residence time of mixture in the bed.
