Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a waste heat recovery boiler, which does not need to have many penetration parts in the ceiling casing of flue by simplifying a support structure of an air-water drum and evaporator pipe bundles. SOLUTION: The support system for pipe bundles 3 is simplified by supporting the lower end of a downcast pipe 4 by a flue bed 6, supporting a steam-water drum 1 above a flue ceiling casing 14 by the downcast pipe 4, and suspending evaporator pipe bundles 3 by riser pipes 2 between the air- water drum 1 and evaporation tube bundle upper headers 11. In addition, supporting the lower part of the steam-water drum 1 by the flue ceiling casing 14 eliminates the necessity of providing a seal structure at each of many penetration parts of the flue ceiling casing 14.
