Zusammenfassung:PROBLEM TO BE SOLVED: To provide an off-gas combustion device capable of surely burning methane in an off-gas when methane is included in the off-gas of a device for separating methane from a biogas, and not needing auxiliary fuel and a special appliance in burning methane in the off-gas. SOLUTION: This off-gas combustion device includes a burner (4) for burning the off-gas of the methane separating device (1), a hollow cylindrical heat chamber (2) constituting a combustion exhaust gas line (Lg) by surrounding the burner (4) and its downstream side, and a combustion air line (LA) in which the air for combustion supplied to the burner flows, and the combustion air line (LA) has flow channels (LA2-LA4) for preheating, formed inside of the heat chamber (2).
