PURPOSE:To conserve energy, by charging oxidizing agent so that the concn. of carbon monoxide generated from a thermal decomposition and melting treatment process of an org. substance reaches 10vol% or more. CONSTITUTION:In a thermal decomposition and melting treatment process of sewage sludge 10, a blower 7 is operated to blow air into a furnace from an air blow-in pipe 5 through a regulation valve 6. A predetermined amount of exhaust gas is sampled to be supplied to a sampling circuit A and the concn. of CO in exhaust gas is measured by a CO-meter 8. The regulation valve 6 is controlled by the measured result and an air blow-in amount is increased or decreased so as to set the concn. of CO in exhaust gas to 25-30vol%.
