<P>PROBLEM TO BE SOLVED: To provide a reheating boiler capable of preventing a loss of combustion due to an excessive rise in a temperature of a reheater pipe by controlling the combustion amount of a reheating burner according to the heat absorption amount of the steam flowing through a reheater. <P>SOLUTION: A reheating boiler 5 includes a main furnace 27 configured so that a combustion gas generated by the combustion of a main burner 33 can flow from a furnace 31 through a superheater 37 and an evaporation pipe bundle 39, a reheating furnace 29 provided with a reheating burner 53 downstream of the evaporation pipe bundle 39 and a reheater 61 disposed on the upper side of the reheating furnace 29, wherein there is provided a combustion amount adjustment controller 77 for adjusting the combustion amount of the reheating burner 53 according to the heat absorption capacity of the steam passing inside the reheater pipe 60 of the reheater 61 so that the steam temperature may not be higher than a predetermined temperature. <P>COPYRIGHT: (C)2012,JPO&INPIT |
