<p>PROBLEM TO BE SOLVED: To provide an exhaust heat recovery boiler capable of preventing degradation in the heat absorption efficiency of a boiler body since a flow of exhaust gas flowing in the boiler body is biased to a partial region.SOLUTION: An exhaust heat recovery boiler recovering heat from high-temperature exhaust gas and configured so that an inlet duct 3 is provided on a side portion of a boiler body 1, the exhaust gas is introduced from an exhaust gas inlet 5 provided in an upper portion of the inlet duct 3, and the exhaust gas is supplied to the boiler body 1 through an opening portion provided in a side portion of the inlet duct 3, comprises a shield plate 7 provided in the opening portion to the boiler body 1 and shielding part of the exhaust gas flowing from the inlet duct 3 to the boiler body 1, the shield plate 7 including holes through which the exhaust gas passes and a shield surface shielding a flow of the exhaust gas, and the shield plate 7 imposing restrictions on the flow of the exhaust gas flowing to a lower portion of the boiler body 1 after reaching a lower portion of the inlet duct 3.</p> |
