摘要： PROBLEM TO BE SOLVED: To provide a waste heat recovery boiler with a stabilizing burner capable of preventing the combustion of a blast furnace gas from being destabilized by holding the temperature of a combustion chamber to a specified gas temperature or higher even when an output requirement for a steam turbine is lowered and a method of operating the waste heat recovery boiler.
SOLUTION: A bypass duct 10 connecting a flue gas flow passage on the upstream side of the stabilizing burner 4 to a boiler body 7 on the downstream side of a heat exchange tube group 13 on the upstream-most side is installed bypassing an inlet duct 3 in which the stabilizing burner 4 is disposed. A damper 11 for controlling the distribution of gas flow is disposed in at least either of the bypass duct 10 and the inside of the inlet duct 3 on the upstream side of the disposed part of the stabilizing burner 4. When a requested evaporation amount is small (supporting amount is small), a gas flow rate flowing in the boiler body 7 is reduced by the damper 11 so that, even if a combustion load by the stabilizing burner is lowered, a flue gas temperature after the stabilization can be maintained at a specified temperature or higher.
