PROBLEM TO BE SOLVED: To eliminate the blockade etc. of an exhaust pipe due to dew condensation so as to improve the heat exchanging efficiency of a catalytic combustor by successively connecting an intake pipe, an intake section, a catalytic combustor, and the exhaust pipe and providing an exhaust top section at the front end of the exhaust pipe and a porous section which covers the outlet of the exhaust pipe in the top section. SOLUTION: An intake pipe 16 communicated with the outside air is connected to an intake section 12. A diffuser 15, a catalytic combustion section 17, an ignition combustion section 18, a trap section 19 constituting an exhaust passage, and an exhaust pipe 20 are successively connected. An intake/exhaust top 22 formed by uniting an intake top section having a hole 21 communicated with the outside air and an exhaust top section in one body is attached to the front ends of the intake pipe 16 and exhaust pipe 20. The top 27 is formed by molding a synthetic resin having low thermal conductivity and, in the intake and exhaust top sections, a clearance 29 is formed and a porous section 30 which covers the outlets of the pipes 16 and 20 is provided. |
