To provide a combustion device capable of efficiently burning combustible waste together with the main fuel such as pulverized coal within a kiln without finely pulverizing the combustible waste like the pulverized coal and of effectively using the combustible waste as heat energy.

The combustion device includes: a waste injection means for injecting the combustible waste from a waste injection port 11 while spirally turning the combustible waste; a first inner-air injection means for injecting air from first inner-air injection ports 31 arranged to surround the waste injection port 11; a second inner air injection means for injecting air from second inner-air injection ports 41 arranged to surround the first inner air injection ports 31; the main fuel injection means for injecting main powder or liquid fuel from main fuel injection ports 51 arranged to surround the second inner air injection ports 41; and an outer air injection means for injecting air from outer air injection ports 61 arranged to surround the main fuel injection ports 51. The injected combustible waste is diffused and mixed with the main fuel while turning, so as to facilitate the complete combustion of the combustible waste.
