ABSTRACT:
An incinerator designed so that the reaction of unburnt gas with oxygen progresses rapidly to thereby minimize the amount of unburnt gas generated therefrom. An intermediate portion of a combustion chamber is contracted in the cross-sectional direction with respect to the direction of flow of gas to thereby provide a throttling passage (14) over a predetermined distance. A part of the combustion chamber which is below the throttling passage (14) and a part of the combustion chamber which is above the passage (14) are enlarged in the cross-sectional direction to define a lower combustion chamber (13) and an upper combustion chamber (15), respectively. A first barrier (16) is disposed in the vicinity of the inlet of the throttling passage (14) across the lower combustion chamber (13) and a second barrier (17) is disposed in the vicinity of the outlet of the throttling passage (14) across the upper combustion chamber (15).
