To provide a combustion deodorization equipment which can efficiently functions even being used in a waste disposal site.

A flame arrester 42 is disposed close to a combustion part 84 in the space between the combustion part 84 and a flue 30. Condensate near the flame arrester 42 is evaporated by the heat of gas combustion. Accordingly water which clogs the arrester 42 does not stay in a pore 72 of the flame arrester 42. As the flame arrester 42, one of crimp ribbon type is used, which has a sufficient strength against mechanical and thermal impacts, and hardly make resistance to the gas fluid.
