The position that described pin middle part is connected with external screw thread is provided with step, is installed in the degree of depth in the screw so that determine pin.

For increasing burning area, make fuel gas buring more abundant, effectively reduce toxic emission, this burner adopts two ring fires design.Fuel chamber comprises inner ring fuel chamber and the outer shroud fuel chamber of global formation, and inner ring fuel chamber and outer shroud fuel chamber arrange with one heart and both link together by crossbeam, are provided with the crossbeam blast tube in the crossbeam; The blast tube of described injector comprises inner ring blast tube and outer shroud blast tube, and the inner ring blast tube is communicated with inner ring fuel chamber, and the outer shroud blast tube is communicated with outer shroud fuel chamber by the crossbeam blast tube; Described fire cover comprises inner-ring fire cover and external ring fire cover, inner ring fuel chamber supporting inner-ring fire cover, outer shroud fuel chamber supporting external ring fire cover.

Be provided with the through hole that connects the fuel chamber upper and lower end face between the crossbeam of described connection inner ring fuel chamber and outer shroud fuel chamber, the inwall of through hole laterally is provided with boss, and locating hole vertically is arranged on the boss.

Described boss and fuel chamber are one-body molded, to simplify working process, enhance productivity.

Also be installed with thermocouple in the described fuel chamber.

The utility model is compared the beneficial effect that produces with background technology:

1, because the utility model is provided with pin at the link position of injector and fuel chamber, adopt pin to replace the rotation of screw restriction fuel chamber, one side has retrained the rotational freedom of fuel chamber effectively, reaches the purpose that prevents fuel chamber's collision ignition electrode; Keep again on the other hand fuel chamber relative to the free degree that injector moves straight up, fuel chamber can freely be installed or removed easily, reached the purpose that makes things convenient for daily cleaning to safeguard burner; Prevented that fuel chamber from because of the monolateral stressed canting that occurs, having ensured the stationarity that fuel chamber cooperates with injector on the one hand again.
