Detailed description of the invention
First boiler is described and for setting up the module of boiler below.
Boiler 1 (Fig. 2 and 3) includes that primary structure 2, primary structure 2 include pylon 3 and the top grid 4 above pylon 3.Primary structure 2 supporting hot exchange surface.Boiler can be any kind of boiler, the most such as pylon boiler or twice boiler.
Primary structure 2 is connected in module 5 and support module 5, and module 5 limits heat exchange surface.According to the specific design of boiler, module 5 can be part or the part of lower person: vaporizer, superheater, reheater, economizer.
Modules 5 includes (Fig. 5-8) outside hanger bearing part 6 and peripheral heat exchange surface 7;Preferably modules limits the cross section of boiler.
Outside hanger bearing part 6 may be connected on peripheral heat exchange surface 7, and such as by post (in any case other example is feasible) supporting periphery heat exchange surface 7.
Outside hanger bearing part 6 can be such as in order to allow steam to cycle through their solid bars or tubular strip, in order to allowing outside hanger bearing part 6 to have the thermal expansion similar with peripheral heat exchange surface 7, and offset the differential expansion in boiler, differential expansion can produce stress.
Peripheral heat exchange surface 7 can be limited by tube wall, and such as they can include pipe 8 and fin 9 (but fin 9 is optional).
Outside hanger bearing part 6 is (the most i.e., supporting member 6 is connected on primary structure 2) or indirectly (i.e., supporting member 6 is connected on another element, and another element is directly or indirectly connected to again on primary structure 2) it is connected on primary structure 2.Preferably, outside hanger bearing part 6 is directly or indirectly connected on upper part and/or the top grid 4 of primary structure 2.
The peripheral heat exchange surface 7 of modules 5 is connected on the peripheral heat exchange surface 7 of another module 5.
In one example (Fig. 9), can be by the peripheral heat exchange surface 7a by realizing different modules 5 on each pipe 8a weld seam of peripheral heat exchange surface 7a to another pipe 8b of peripheral heat exchange surface 7b, the connection of 7b.Label 11 indicates the weld seam between pipe 8a, 8b.Preferably, also between fin 9a, 9b of peripheral heat exchange surface 7a, 7b, weld seam 11 is provided.
