OPTIMIZATION OF THE OXIDIZER REPARTITION IN ORDER TO REDUCE THE NO EMISSIONS IN MUNICIPAL WASTE INCINERATION

摘要

An experimental study has been conducted with a fixed-bed reactor to simulate, on a laboratory scale, industrial municipal waste incineration. The observation of the combustion regimes established has served to show the impact of the operating conditions on the yields of nitrogen oxide. Two different regimes have been identified, controlled by the airflow rate through the fuel. The present experimental results show that the production of NO seems to be controlled only by the oxygen concentration in the secondary zone of combustion. An increase in total air-flow rate, thus, results in an increase in the yield of NO.
