PROBLEM TO BE SOLVED: To restrain a vortex from being generated on a downstream side in a gas flow direction.SOLUTION: A baffle 5 is provided in an internal space of a boiler casing 2 between an inlet duct 2a and a heat exchange part. The baffle 5 comprises a plurality of flat plates and bent plates for partitioning a gas channel. The angle and length of the plurality of flat plates and bent plates are designed so that the ratio of a channel area on a gas outflow side to a channel area on a gas inflow side partitioned with the plurality of flat plates and bent plates can become lower as a distance from an outlet duct 2b becomes longer. |
