PURPOSE:To make the flow of internal fluid excellent, by changing the widths of heat transfer pipe panels in correspondence with the arranged space of each heat transfer pipe panel, and arranging the heat transfer pipes approximately evenly when viewed from the upstream side of a gas flow with respect to the cross section of the path of a heated fluid in a traversed an distributed pattern. CONSTITUTION:The widths of a panel 10a... a panel 10g are made different in correspondence with the arranged spaces. Heat transfer pipes are evenly arranged with respect to the cross section of the flow path of exhausted gas G. The panels 10a-10g are connected to an input header 12 and an output header 13, respectively. Thus one unit-heat-transfer pipe group 8A is formed. In this constitution, water, which is supplied into the pipe, always becomes a climbing stream since the panel surface is inclines with respect to gravity. An air-water mixed body clibms excellently. During this time, heat is exchanged with the exhaused gas G, and said mixed body reaches the output header 13. Therefore, the internal fluid flows excellently, and heat recovering efficiency can be enhanced. |
