PURPOSE:To enhance supporting strength and contrive to prevent resonance of heat-transmitting pipes, by supporting each of the heat-transmitting pipes by a horizontal supporting plate. CONSTITUTION:The horizontal supporting plate 16 in at least one stage with respect to the direction of height of the heat-transmitting pipes 12 fitted with fins 13 is placed orthogonally to the pipes 12, and, in a direction orthogonal to the flowing direction of a waste gas, vertical supporting plates 18 are placed orthogonally to the horizontal supporting plate 16. Accordingly, supporting strength for the elongated and enlarged heat-transmitting pipes is enhanced, and it is contrived to prevent resonance of the heat-transmitting pipes, particularly the finned ones which are difficult to support. |
