Combustion in C_2/Air Atmosphere for Waste in Bench-Scale, 2nd Report

Abstract

We have developed the new MSW incineration system that is characterized by the combustion using the addition of oxygen to combustion air and flue gas recirculation ( FOR ) from outlet of bag filter. The tests to optimize operate condition were carried out in bench-scale facility. Costs, solid combustion, dioxin emission and NOx emission were evaluation items to optimize operate condition. It was found out the optimized oxygen concentration in combustion air to decrease costs, promote solid combustion and repress dioxin emission. However, optimized FGR condition to repress dioxin and NOx emission was not found out. Effects of FGR are influenced by the furnace geometry and combustion state. So optimized FGR conditions should be examined in each facility.
