Zusammenfassung: | PURPOSE:To prevent a smoke chamber at a hot air heater from being etched by acid generated through dew formation of water vapor contained in combustion gas. CONSTITUTION:A donut-shaped buffle 28 is arranged at a smoke chamber 16A of a hot air heater 10. Combustion gas passes through a hollow part 28A of the buffle and flows along a tube plate 27 or a wall surface of a smoke chamber barrel 26, thereby temperatures of the tube plate 27 and the wall surface of the smoke chamber barrel 26 are increased and the dew formation water is prevented from being made at the wall surface. |
