HEAT TRANSFER PIPE SUPPORT STRUCTURE AND WASTE HEAT RECOVERY BOILER

摘要

A heat transfer pipe support structure (1) is provided with: a heat transfer pipe support plate (2) having through-holes (6-(i, j)) formed therein; heat transfer pipes (3-(i, j)) inserted through the through-holes (6-(i, j)); and a vibration-damping support plate (5-j) joined to the heat transfer pipe support plate (2). An edge of the vibration-damping support plate (5-j) is joined to the heat transfer pipe support plate (2) in such a manner that the heat transfer pipes (3-(i, j)) are gripped between edges of the through-holes (6-(i, j)) and the vibration-damping support plate (5-j). In the above-described heat transfer support structure (1), due to the fact that the heat transfer pipes (3-(i, j)) are gripped between the edges of the through-holes (6-(i, j)) and the vibration-damping support plate (5-j), the clearance between the edges of the through-holes (6-(i, j)) and the heat transfer pipes (3-(i, j)) is reduced, and consequently, the vibration of the heat transfer pipes (3-(i, j)) can be reduced. The reduction in the vibration of the heat transfer pipes (3-(i, j)) can reduce the sliding between the heat transfer pipes (3-(i, j)) and the edges of the through-holes (6-(i, j)), and consequently, wear is reduced.
