Fuzzy Combustion Control for Reducing Both CO and NOx from Flue Gas of Refuse Incineration Furnace

NKK developed a new combustion controller that reduces both NOx and CO concentrations in the exhaust gas of municipal refuse incineration furnaces. We found that the manipulation of the cooling air flow rate is important because it affects the furnace temperature and the O2, NOx and CO concentration...

Zusammenfassung:	NKK developed a new combustion controller that reduces both NOx and CO concentrations in the exhaust gas of municipal refuse incineration furnaces. We found that the manipulation of the cooling air flow rate is important because it affects the furnace temperature and the O2, NOx and CO concentrations in the exhaust gas. The new controller manipulates the cooling air flow rate. The controller monitors the furnace temperature and the O2, NOx and CO concentrations as process variables and then operates the cooling air flow rate as a manipulated variable. This multi-input / single-output controller was designed using a fuzzy control algorithm and tested on site at a municipal refuse furnace. The result of the on-site test was quite successful.
