Abstract

A boiler structure for vessel in which partial progress of corrosion is improved by making temperature distribution of combustion gas passing through a superheater uniform and the NOx level of combustion gas can be reduced. In the boiler structure for vessel configured such that the combustion gas generated through combustion of a burner (3) flows from a fire furnace (2) through a superheater (5) and an evaporation pipe group (6), a bottom air port (20) for supplying a part of combustion air from the bottom (2a) of the furnace (2) as bottom air is provided, the bottom air port (20) is located closer to the superheater (5) side than the center line (CL) of the burner, and a blow-off direction of bottom air is set in a range inclining from vertical upward to the direction of the burner.
