PROBLEM TO BE SOLVED: To provide a flammable gas combustion treatment device capable of preventing internal corrosion caused by sucking moisture in a gas pipe in a bubble cap type burn-pond for burning and treating a flammable gas. SOLUTION: An openable and closeable cover structure 20 is mounted on a tip of a discharge pipe 12 of a bubble cap 10, thus an outlet of the discharge pipe 12 can be opened in operation, and closed in pause. The cover structure may be constituted to be automatically opened and closed by using a float 26 floating on the water or a stop cock 31 opened and closed by gas pressure difference in the discharge pipe, or may be opened and closed by simple manual operation.
