Influence of the temperature in the post-combustion chamber of cremators on the CO concentration in the exhaust gas

摘要

A detailed chemical kinetic model was used to simulate the CO content in the exhaust gas of crematories under process-typical conditions. It was presumed that oxidation of CO to CO2 essentially takes place in the post-combustion chamber. A qualitative relation between CO content, O-2 content, and temperature that was taken from the literature could be confirmed and quantified. From the calculations, it follows that maintenance of the legal minimum temperature of 850 degrees C in the post-combustion chamber is necessary to comply with the CO legal emission limit of 50 mg/m(3).
