    • PROBLEM TO BE SOLVED: To provide a boiler and a steam temperature adjusting method for the boiler, which perform an efficient operation by adjusting the pattern of the flow of a combustion gas generated in combustion of a burner and controlling the temperature of the steam produced in a superheater.
      SOLUTION: In this boiler 10A constituted to allow the combustion gas generated in the combustion of the burner 101 to flow from a furnace 102 through a superheater (SH) 104 and a group of steam generating tubes 105, a downstream portion blocking plate 11A slidable in the vertical direction of the superheater 104 is disposed on a wake side of the combustion gas in an upper portion of the superheater 104 to adjust a flow rate of the combustion gas entering an upper space A of the superheater 104. By adjusting a flow rate of a bypass gas 12 by the downstream portion blocking plate 11A and also adjusting a flow rate of a mainstream gas 13, the steam temperature of the superheater 104 is controlled.

    • PROBLEM TO BE SOLVED: To provide a steam temperature reducing device causing no temperature unevenness in temperature-reduced steam by mixing high temperature steam and a cooling fluid wholly and uniformly.
      SOLUTION: A cooling fluid supply part 2 and a heat exchange part 3 are sequentially connected to a high temperature steam supply pipe 1. A cooling fluid pipe 6 is connected to the cooling fluid supply part 2. An internal passage 7 of the heat exchange part 3 is connected to the cooling fluid supply part 2 and a temperature-reduced steam supply pipe 9, respectively. A spiral outer peripheral passage 10 is disposed at the outer periphery of the internal passage 7. The outer peripheral passage 10 is in communication with a cooling fluid tank 4 and a circulating pump 11. The high temperature steam supplied from the high temperature steam supply pipe 1 is mixed with the cooling fluid raised in temperature in the cooling fluid supply part 2, and reduced to a predetermined temperature without temperature unevenness.
