Advanced Combustion Control System by Real-time Measurement of CO, O_2 Concentration in Refuse Incineration Plant

摘要

In refuse incineration plants, the regulation of exhaust gas has become stricter and the simultaneous reduction of CO, NOx and dioxins has become an operation requirement. To ensure such reduction, it is necessary to increase the stability of combustion and to detect combustion status quickly and certainly and control combustion air. We measured the concentration of O_2 and CO in the furnace using laser absorption spectroscopy and applied combustion control. We thus confirmed simultaneous reduction of CO by 41 percent and NOx by 15 percent.
