Device technique field.
Background technology
At present, the commonly used hanging of coil heating surface such as the low temperature superheater of boiler for high power station, low-temperature reheater
Pipe, the load of coil is passed to suspension rod and boiler steel structure by hanging pipe.When mounted, supported by welding on hanging pipe
Otic placode bears the load of tube panel heating surface, hanging pipe is generally arranged at the centre of adjacent two coils, by a hanging
Pipe bears the load of two panels tube bank.In conventional project, the gap between hanging tube and tube screen heating surface is the least.
As shown in Figure 1,2,3, 4, existing low again, low tube panel of crossing is made up of several coils, wherein: coil 102 leads to
Crossing support otic placode 103 to fix with hanging pipe 101, two coils 102 are respectively by two support otic placodes 103 and a hanging Guan Lian
Connect formation one.A diameter of D1 of hanging pipe 101, low again, the low a diameter of D2 of coil 102 crossing tube panel, adjacent two snakelike
Pitch between pipe 102 tube panel is S, and the pitch of hanging pipe 101 is 2S, and tube panel pitch S of the coil of conventional design is typically somewhat
More than D1+D2, i.e. S ≈ (1.0～1.1) × (D1+D2), become fine pith S-shaped tube panel.Due to the restriction of the conditions such as ature of coal,
Existing fine pith coil heating surface can not meet engine request, it has to strengthens the pitch of coil heating surface, uses
Wide pitch coil, this will cause the increase hanging pipe support otic placode length.
As shown in Figure 5,6, when coil 102 heating surface spacing increases, the length supporting otic placode 103 increases accordingly.By
It is exposed in high-temperature flue gas be heated in supporting otic placode 103, when the length supporting otic placode increases, it will cause the temperature supporting otic placode
Degree increases, and need to use the material than hanging pipe 101 greater degree, owing to material is different, temperature stress can be caused relatively big, use the longevity
Life is substantially reduced, if supporting otic placode breakage occurs, it will jeopardize safe operation of the boiler.
