Description
Technical field
It the utility model is related to boiler plant technical field, the four of especially a kind of Small And Medium Capacity combustion gas water pipe steam boiler
Membrane wall symmetrical structure.
Background technology
Medium and small gas-steam boiler is typically substantially divided to two classes, shell fire tube and drum water pipe.
Small And Medium Capacity combustion gas water pipe steam boiler is usually three membrane walls or four membrane wall unsymmetric structures.By thermal effect
Difference.
Utility model content
A kind of the shortcomings that the applicant is directed in above-mentioned existing production technology, there is provided Small And Medium Capacity combustion gas water pipe steam boiler
Four membrane wall symmetrical structures, so as to use four membrane wall symmetrical structures, it is good by thermal effect and safe.
Technical scheme is as follows used by the utility model：
A kind of four membrane wall symmetrical structures of Small And Medium Capacity combustion gas water pipe steam boiler, include the furnace wall of interval installation, institute
The both sides for stating furnace wall are separately installed with symmetrical inner side membrane wall, the outside installation convection tube of inner side membrane wall, convection tube it is outer
The inner side membrane wall of portion installation outside membrane wall, two sides furnace wall and both sides defines burner hearth, is set in the middle part of the furnace wall of one end
There is combustion port, protection pipe is installed positioned at the inner side of other end furnace wall；The outside installation of the furnace wall and outside membrane wall is protected
Warm layer.
Its further technical scheme is：

It is and safe.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：1st, heat-insulation layer；2nd, furnace wall；3rd, outside membrane wall；4th, convection tube；5th, combustion port；6th, inner side membrane wall；
7th, protection pipe；8th, burner hearth.
Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is illustrated.
As shown in figure 1, four membrane wall symmetrical structures of the Small And Medium Capacity combustion gas water pipe steam boiler of the present embodiment, including
Every the furnace wall 2 of installation, the both sides of furnace wall 2 are separately installed with symmetrical inner side membrane wall 6, the outside installation pair of inner side membrane wall 6
The inner side membrane wall 6 of flow tube 4, the outside installation outside membrane wall 3 of convection tube 4, two sides furnace wall 2 and both sides defines burner hearth 8, position
The middle part of furnace wall 2 of one end is provided with combustion port 5, protection pipe 7 is installed positioned at the inner side of other end furnace wall 2；Furnace wall 2 and outer
The outside installation heat-insulation layer 1 of side membrane wall 3.
6 two-sided heating surfaces of inner side membrane wall.
3 one side heating surfaces of outside membrane wall.
The both sides of burner hearth 8 are symmetrical inner side membrane wall 6, and this twice membrane wall one side is conducted heat by the flame radiation of burner hearth 8, one
Convection heat transfer' heat-transfer by convection of the face by high-temperature flue gas；Outermost sealing membrane wall is also symmetrical twice, by the convection heat transfer' heat-transfer by convection of high-temperature flue gas.
Main feature of the present utility model：
First, symmetrical structure, relative to unsymmetric structure expansion evenly, security is higher.
Second, four membrane wall structures, there is six heating surfaces, wherein four convection heating surfaces are all in high-temperature flue.It is relative with
Conventional three membrane wall structures (sharing four heating surfaces, wherein two panels is convection heating surface) two panels convection heating surface more, is heated
Effect affirmative is more preferable；(six heating surfaces are shared, wherein the two panels in four convection heating surfaces relative to conventional four film-type wall boilers
In low temperature flue), convection heating surface four is all heated in high-temperature flue internal ratio two panels in high-temperature flue two panels in low temperature flue
Effect is more preferable.
Above description is to explanation of the present utility model, is not the restriction to utility model, what the utility model was limited
Scope within the scope of protection of the utility model, can make any type of modification referring to claim.
