<p><P>PROBLEM TO BE SOLVED: To provide a swing stopping structure for heat transfer pipes, which prevents swinging of the boiler heat transfer pipes and prevents the inflow of combustion ash inside a female metal fitting to prevent deposition. <P>SOLUTION: In the swing stopping structure 11 for the heat transfer pipes, a first linear heat transfer pipe 12 and a second linear heat transfer pipe 13 adjacent to each other out of the boiler linear heat transfer pipes arranged approximately in parallel with each other are engaged with each other to suppress the swinging of the heat transfer pipes 12, 13. The the swing stopping structure 11 includes: the female metal fitting 14 provided in the first linear heat transfer pipe 12, having a pair of sidewalls 18, 18 and including a groove 21 forming a first opening 20 opened toward the second linear heat transfer pipe 13 between the sidewalls 18 by the pair of the sidewalls 18, 18; and a male metal fitting 15 provided in the second linear heat transfer pipe 13 arranged in the first opening 20 and the groove 21 of the female metal fitting 14. The female metal fitting 14 is formed so that the opening direction of the first opening 20 is set to be approximately equal to the flowing direction 8 of combustion gas for heating fluid within the first and second linear heat transfer pipes 12, 13. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
