[Abstract]

This system is one that set up an infrared scanner in the second furnace at Kuzuoka incineration plant in Sendai City in November, 2002, improved the combustion measurement system and was done in a joint research project with Sendai City. We set up the infrared camera in the first furnace at Clean 21 Haseyama incineration plant of the Johnan Hygienic Management Union. Then we designed and experimented with the combustion control system and tried to decrease CO and NOx concentration in the exhaust gas and remained carbon in the combustion ash by detecting the starting point (ignition point) in the main combustion area and the terminal point (burnout point) by analyzing the results of the heat image data from the infrared camera that measures refuse layer surface temperature/distribution in a real furnace, and control it at a proper position. We have shown the capability of combustion control using the infrared image measurement.
