<p>PROBLEM TO BE SOLVED: To provide a waste heat boiler unit and a waste heat boiler capable of heating water by heat of combustion gas.SOLUTION: A waste heat boiler unit 1 comprises: a casing 10 having an introduction port 11 for introducing combustion gas and an exhaust port for exhausting the combustion gas; plural water pipes arranged in the casing 10 and warming and heating water flowing inside by heat of the combustion gas; and a heat transfer member for connecting the water pipes. A continuous flow passage surrounded by the water pipes and the heat transfer member and allowing the combustion gas to pass from the introduction port 11 to the exhaust port is formed. The flow passage has horizontal flow passages for the combustion gas flowing in a horizontal direction, and vertical flow passages for the combustion gas flowing in a vertical direction. Plural rows of horizontal flow passages are formed in both of a vertical direction and a horizontal direction. The horizontal flow passages arranged in the vertical direction are communicated with each other by the vertical flow passages. The combustion gas flowing from the introduction port 11 is bent in the vertical direction and the horizontal direction, and exhausted from the exhaust port.</p> |
