Abstract
A flammable-gas led-out pipe () has a terminal end portion () disposed in an exhaust-gas route () and a metal cylinder () is arranged at the terminal end portion () of the flammable-gas led-out pipe (). An oxidation catalyst () is disposed within the metal cylinder (). On an upstream side of the oxidation catalyst (), an air-supply passage () is opened to provide an outlet () and the flammable gas () merges with supplied air (). The flammable gas () is burnt with the oxidation catalyst () to produce catalyst-combustion heat, which is radiated from an outer peripheral surface of the metal cylinder () into the exhaust gas () in the exhaust-gas route () and the exhaust gas () heated by this heat-radiation is mixed with the flammable gas () that has passed through the oxidation catalyst ().
