Description
Technical field
The invention belongs to gas fired-boiler technical field, particularly a kind of back-end surfaces sealing supporting structure and there is the industrial tail gas boiler of this structure.
Background technology
Current gas fired-boiler complex structure, its back-end surfaces is supported by outside steelframe, is arranged in the side of boiler body.Outside steelframe makes the floor space of whole boiler increase, and security system reduces.Flue side arrangement, makes the formation dead angle, top of burner hearth, and overhead gas is not easy discharge.
In addition, because side flue washes away expansion by high-temperature flue gas, easily produce swelling stress, cause structural deterioration and support function to decline.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of back-end surfaces sealing supporting structure and there is the industrial tail gas boiler of this structure, to the arrangement by changing flue, improving sealing and the structural strength of boiler flue.
The technical scheme that the present invention takes is:
A kind of back-end surfaces sealing supporting structure, comprise floss hole, it is characterized in that, above described floss hole, a support member is set by top header, an accommodating cavity is formed in the middle of the header of described top, sheathed sealing flue in described accommodating cavity, the size of described accommodating cavity is greater than the outside dimension of described sealing flue, described sealing flue upper end is connected with support member, lower end and the described floss hole of described sealing flue are tightly connected by an expansion joint, connect back-end surfaces at the upper seal of described support member.
Further, one end of described support member is fixedly connected with described top header, and the other end of described support member is flexibly connected with described top header.
A kind of industrial tail gas boiler with above-mentioned back-end surfaces sealing supporting structure, comprise drum, burner hearth, it is characterized in that, described burner hearth is horizontal straight tube shape, burner is provided with at the first end of described burner hearth, described back-end surfaces sealing supporting structure is set above the second end of described burner hearth, above described back-end surfaces sealing supporting structure, sets gradually economizer and air preheater.
Further, described drum is arranged on the top of described burner hearth.
Further, in described burner hearth, near described burner hearth second end, superheater is installed.
Further, the cross section of described burner hearth is approximate parallelogram, and dual-side is perpendicular to horizontal plane, and upper bottom is horizontal by a positive angle.
The invention has the beneficial effects as follows:
(1) supporting construction of back-end surfaces makes back-end surfaces be arranged in the top of boiler body, decreases the floor space of boiler, and apparatus arrangement is more smart gathers;
(2) good sealing effect of the hermetically-sealed construction of back-end surfaces, not by the impact of its thermal expansion;
(3) thermal expansion of back-end ductwork is offset by active connection part and expansion joint.
