PROBLEM TO BE SOLVED: To provide an exhaust heat recovery boiler for heating a water pipe provided in a boiler body part by flowing exhaust gas through the boiler body, in which an absorption amount of heat in the boiler body increases.SOLUTION: The exhaust heat recovery boiler comprises an inlet duct 3 and an outlet duct 4 provided at positions on the opposite sides of the boiler body 1, and is configured to heat the water pipe provided in the boiler body part by the exhaust gas. The exhaust heat recovery boiler is provided with: a lower guide plate 11 extending in a direction parallel to the water pipe, and having a surface for blocking the flow of exhaust gas in the lower portion of an exhaust gas flow path of the boiler body 1; and an upper guide plate 7 extending in the direction parallel to the water pipe, and having a surface for blocking the flow of exhaust gas in the upper portion of the exhaust gas flow path of the boiler body. The lower guide plate 11 and the upper guide plate 7 are arranged at intervals in the flow direction of exhaust gas so that a stream of the exhaust gas flowing through the boiler body 1 meanders. |
