CONTROLLING METHOD OF COMBUSTION STATE IN MUNICIPAL WASTE INCINERATOR

摘要

PURPOSE:To stabilize the combustion in an incinerator and to raise a combustion efficiency by a method wherein a methane gas obtained from a raw refuse fermentation device is supplied as an auiliary fuel or a gas for adjusting the temperature of the exhaust gas temperature at the outlet port of the incinerator. CONSTITUTION:A municipal refuse 1 is sorted into a combustible material 3 and raw refuse 4 through a sorter 2. The conbustible material 3 is cast into an incinerator 6 from a hopper 5. Whereas, the raw refuse 4 is fed into a raw refuse fermentation device 8 to be performed with a fermentation processing. A methane gas generated from the fermentation is stored in a gas tank 9 and it is supplied to a burner 11 for the auxiliary combustion use and a burner 10 for the adjustment of the exhaust gas temperature of the incinerator 6.
