Abstract
The utility model relates to a flame tube of a combustion chamber, comprising a flame tube body and a flame tube head. The flame tube has the point that the flame tube head comprises a head panel, a mounting ring and an air swirler; the mounting ring is provided with internal screw threads; the outer ring of the air swirler is provided with external screw threads; the mounting ring and the air swirler are connected by the internal screw threads and the external screw threads thereon, and are fixedly connected on the head panel of the flame tube. The air swirler on head of the flame tube of combustion chamber adopts threaded connection with simple structure and easy manufacture; the air swirler can be assembled, disassembled, and replaced conveniently, and also can be washed easily, thereby reducing the manufacturing cost of the flame tube, reducing the repairing and maintaining cost of the flame tube, and prolonging the service life of the flame tube.
Description
Technical field
The utility model relates to a kind of combustion chamber flame drum, is specifically related to a kind of gas turbine combustors burner inner liner.
Background technology
Burner inner liner is the vitals of gas turbine combustors, burner inner liner mainly is made up of the air swirler of cylindrical shell and burner inner liner head, traditional burner inner liner is that air swirler and burner inner liner head panel are welded together, connect reliable, but cylindrical shell is easy to generate welding deformation during welding, influences the performance of combustion chamber.In order to prevent welding deformation, positioning tool anchor clamps that can design specialized, guarantee that cylindrical shell is indeformable when welding, this just must increase the burner inner liner processing cost, and burner inner liner is a high-temperature component in addition, working time has been grown back air swirler and phenomenons such as carbon deposit, ablation, crackle can occur, burner inner liner maintenance clean difficulty is changed the air swirler of ablating or crackle being arranged, and can only take cutting mode, this mode is damaged the cylindrical shell of burner inner liner easily, has also increased maintenance cost simultaneously.
Summary of the invention
The purpose of this utility model is the defective that overcomes the deficiencies in the prior art and existence, provides a kind of simple in structure, and maintenance clean and mounting or dismounting are convenient, the combustion chamber flame drum of long service life.
For achieving the above object, combustion chamber flame drum of the present utility model comprises burner inner liner cylindrical shell and burner inner liner head, it is characterized in that: described burner inner liner head includes head panel, installing ring and air swirler, installing ring is provided with internal thread, the outer shroud of air swirler is provided with external screw thread, and installing ring is connected by the internal and external screw thread on it with air swirler and is fixed on the head panel of burner inner liner.
In order to realize this purpose better, described installing ring is a T shape.
The air swirler of combustion chamber flame drum head of the present utility model has adopted and has been threaded, simple in structure, easy to manufacture, it is convenient that the air swirler mounting or dismounting are changed, easy cleaning, reduced the manufacturing cost of burner inner liner, also reduce the maintenance and the maintenance cost of burner inner liner, prolonged the service life of burner inner liner.
Description of drawings
Fig. 1 is the structural representation of the utility model combustion chamber flame drum.
Fig. 2 is the structure enlarged diagram of burner inner liner head 1.
Among the figure: 1, burner inner liner head, 2, gasket ring, 3, cylindrical shell, 4, air swirler, 5, installing ring, 6, the head panel.
The specific embodiment
Combustion chamber flame drum of the present utility model is made up of burner inner liner head 1 and cylindrical shell 3.Installing ring 5 is designed to T shape structure, and the bottom is for installing the limit, and extension is provided with internal thread.The end of thread of the installing ring 5 of T shape structure passes head panel 6 in burner inner liner, the installation limit of installing ring 5 and the inner edge of head panel 6 are fitted, gasket ring 2 is enclosed within on the installing ring 5, be pressed on the outside of head panel 6, air swirler 4 screws in the installing ring 5, head panel 6, gasket ring 2 are pressed between installing ring 5 and the air swirler 4, and air swirler 4 is connected by the internal and external screw thread on it with installing ring 5 and is solid on head panel 6.Loosening in order to prevent air swirler 4, after air swirler 4 screws with installing ring 5, the local spot welding of air swirler, head panel and gasket ring.
