<P>PROBLEM TO BE SOLVED: To provide a boiler device raising an outlet steam temperature of a reheater during a low load without complicating a system construction or increasing costs. Ž<P>SOLUTION: In the boiler device having a hanging type reheater 4a installed in a flue horizontal part 2a connected to an outlet part of a furnace 1 with a portion having a large heat transfer area disposed at an underside of the flue horizontal part 2a, the hanging type reheater 4a has a steam flow passage connected upward from a horizontal transverse-installed type reheater, bent forward in the horizontal direction of the furnace 1 in the range of a vertical direction height of 1/3 to 3/4 of the flue horizontal part 2a, then bent downward to the bottom of the flue horizontal part 2a, and formed flow from a ceiling wall to the outside of the furnace 1 by being reversed near the bottom of the flue. Otherwise, the heat transfer area is preferably formed such that the ratio of an upper half of the flue horizontal part 2a to a lower half of the flue horizontal part 2a is 1:1.8 to 1:4.
