Abstract
The utility model relates to a high strength diaphragm type water cooled wall used for a boiler, the high strength diaphragm type water cooled wall is characterized in that a row or a plurality of rows of pipes are additionally arranged on the heating surface of a main diaphragm type water cooled wall, the additionally arranged one row or a plurality of rows of pipes are arranged corresponding to the pipes of the main diaphragm type water cooled wall, which can be arranged continuously or intermittently, and the corresponding pipes are connected through fins. For a double heating surface boiler with large capacity and large size, the utility model can not only increase the heating surface, but also effectively enhance the rigidity and the intensity of the diaphragm type water cooled wall, in particular has large superiority for the double heating surface diaphragm type water cooled wall which has large pressure fluctuation and which can not be arranged with a rigid beam.
Description
The utility model belongs to the structural design of boiler component, relates in particular to a kind of being arranged in and absorbs photothermal fin panel casing in the burner hearth.
At present, on boiler, use maximum water-cooling walls that bare-tube wall and extended surface tube fin panel casing are arranged.
Bare-tube wall is simple in structure, and is easy to manufacture, do not bear the pressure of surveying from flue gas, and the sealing of burner hearth mainly relies on the furnace wall that is positioned at the water-cooling wall outside to solve.Therefore on malleation or pressurized furnace, use and be very limited.Industrial Boiler generally adopts bare-tube wall.
The extended surface tube fin panel casing is made up of light pipe and fin, can be divided into two kinds of weldering system extended surface tube fin panel casing and rolling extended surface tube fin panel casings by its manufacturing process.The fin panel casing air-tightness is good, and minimizing is leaked out, and makes burner hearth can adopt pressure combustion, and furnace wall only need be used light-duty heat-insulating material, and is convenient to adopt overhung construction, is easy to combination and installs.In addition, it is little also to have amount of stored heat, can shorten to start and furnace outage time, reduces advantages such as metal wastage.In the bigger boiler of capacity, generally use fin panel casing.In pressurized furnace, and even as cyclone furnace, bubbling fluidized bed boiler, CFBB pressurized fluidised-bed boiler, the performance of fin panel casing obviously is better than bare-tube wall.But this class water-cooling wall in use, if its pressure at both sides difference of bearing is bigger, then can only be that single face is heated, and at non-heat side fixedly buckstay need be set, and to guarantee the rigidity of fin panel casing, prevents fluctuation or reduce fluctuating range.And, require the pressure differential of both sides can not be too big for the two-sided fin panel casing that is heated of large scale, fluctuation can not be arranged.Solve the common method that adopts the coordinated transposition of adjacent heating surface part pipe to support mutually of way of this class problem in the prior art.But in some cases, the coordinated transposition of pipe is unallowed, as causing wearing and tearing in the fluidized-bed combustion boiler.Along with the increase of boiler capacity, the stiff problem of the two-sided fin panel casing that is heated of large scale is more outstanding, and this is that conventional fin panel casing institute is irrealizable.
The purpose of this utility model and task are for the two heating surface boilers of big capacity large scale provide a kind of high strength membrane type water-cooling wall, make it can not only increase heating surface area, and can effectively improve the rigidity and the intensity of heating surface.
Purpose of the present invention and task make and are achieved through the following technical solutions: high strength membrane type water-cooling wall that a kind of boiler is used, it comprises by an array of pipes and is arranged on the main fin panel casing that fin constituted between the pipe, it is characterized in that setting up a row or multi-row pipe in the heating surface side of main fin panel casing, the corresponding layout with the pipe of main fin panel casing of the pipe of described a row or multi-row pipe is connected with fin between pairing pipe.
The above-mentioned a row or multi-row pipe of setting up can be according to the structure of the capacity and the heating surface of boiler, adopts continuously or is interrupted the form of arranging.
The heating surface side that accompanying drawing 1 is illustrated in main fin panel casing has increased the pipe that a row arranges continuously.
The heating surface side that accompanying drawing 2 is illustrated in main fin panel casing increases the pipe that row's interruption is arranged.
The heating surface side that accompanying drawing 3 is illustrated at main fin panel casing increases the pipe that many rows arrange continuously.
The heating surface side that accompanying drawing 4 is illustrated in main fin panel casing increases the pipe that many row's interruptions are arranged.
Describe concrete structure of the present utility model and preferred forms in detail below in conjunction with accompanying drawing:
This kind high strength membrane type water-cooling wall is that the heating surface side at main fin panel casing 1 increases a row or multi-row pipe, main fin panel casing is made of pipe 2 and the fin 3 that is arranged between the pipe, the corresponding layout of the pipe of a row or multi-row pipe of being set up with the pipe of main fin panel casing, between pairing pipe, be connected with fin 4, constitute one with fin panel casing, pipe can adopt welding with being connected of fin.The row's number that is increased and every comb subnumber should specifically be decided according to the structure of boiler capacity and main fin panel casing, can adopt single (as shown in Figure 1), also can adopt many rows (as shown in Figure 3); Can adopt continuous layout (as shown in Figure 2), also can adopt and be interrupted the form (as shown in Figure 4) of arranging.
The utility model compared with prior art, have the following advantages and beneficial effect: for big capacity and the two heating surface boilers of large scale, can not only increase heating surface area, can effectively improve simultaneously the rigidity and the intensity of fin panel casing, especially the two-sided fin panel casing that is heated that bigger for pressure oscillation, buckstay can't be provided with, effect is obvious.
