Specific embodiment

Below by embodiment, and combine accompanying drawing, technical scheme is described in further detail.

Embodiment：The super-steady state burner of the present embodiment, as shown in Figure 1, Figure 2 and Figure 3, including chassis 1, is placed on chassis Internal ring mixing chamber 2, interior ring fire cover 3, outer shroud mixing chamber 4, external ring fire cover 5 and igniter, igniter includes pulse generation Device, it is placed on burner chassis and is located at electrode needle 6, electrode needle and pulse generation between internal ring mixing chamber and outer shroud mixing chamber Device electrically connects, and interior ring fire cover and external ring fire cover is designed with the double fire hole of up-down structure, including on equally distributed Row's fire hole 7 and lower row's fire hole 8, the diameter of upper row's fire hole is less than the diameter of lower row's fire hole, the outlet of upper row's fire hole and lower row's fire hole Outlet interlaced arrangement, the duct of upper row's fire hole is horizontal, and the duct of lower row's fire hole is oblique, and the direction of lower row's fire hole is It is inclined upwardly from inside to outside and channel diameter is in gradually to be incremented by shape, the fire hole corresponding with electrode needle section on wherein interior ring fire cover For fire hole, it is designed with the spoiler 9 with interior ring fire cover integrative-structure above fire hole, electrode needle section is located under spoiler Side and corresponding flow-disturbing front edge of board, spoiler can block fire hole and electrode needle, and electrode needle section can be put to spoiler front end high Electricity, flow-disturbing front edge of board is in sector structure be designed with reclinate bending part 10, bending part and spoiler front edge width Match, the extension line of igniting axially bored line is intersected with bending part.

Open burner, combustion gas mixes an air intake by induction tunnel and forms fuel gas mixture, and enters internal ring mixing chamber With outer shroud mixing chamber, the combustion gas entering internal ring mixing chamber is by the oblique ejection of lower row's fire hole of interior ring fire cover and upper row's fire hole level Spray, the mixed airflow wherein spraying from fire hole encounters spoiler bottom surface and bending part, form vortex shape combustion gas cloud cluster and cover Lid electrode needle section, when electrode needle sends high tension spark, ignite combustion gas cloud cluster immediately, and to both sides diffusion, ignite its ember The air mixture that hole sprays, meanwhile, the air mixture of external ring fire cover fire hole ejection of also having been ignited by fire tank, complete burner Igniting and burning.

When combustion gas is in low-pressure state, steadily, flame is in that advection burns to the gaseous mixture flow velocity that double fire hole sprays, and burning is steady Fixed, tempering phenomenon will not be produced.

And when combustion gas air pressure increases, now, the horizontal gas flow speed that upper row's fire hole sprays is accelerated, meanwhile, lower row's fire hole The oblique air-flow spraying also accordingly improves flow velocity, and the gaseous mixture that double fire hole sprays intersects impact, formed turbulent so that Auxiliary air combined amount increase, burn rate accelerate and cross hedge burning, due to two flames mutually pin down and auxiliary air mix Resultant, greatly it is not easy to produce from flame phenomenon, accordingly can increase the spacing of fire hole, prevent the generation of Huang Yan.
