Stable-flame burner

Abstract

The invention relates to a stable-flame burner which comprises a base, an internal ring gas mixing chamber and an external ring gas mixing chamber which are arranged on the base, an internal ejector tube communicated with the internal ring gas mixing chamber, an external ejector tube communicated with the external ring gas mixing chamber, an internal ring fire cover and an external ring fire cover, wherein the top surface of the internal ring fire cover is provided with a central fire hole positioned at the center and peripheral fire holes around the central fire hole; the air duct between the internal ring fire cover and internal ejector tube is divided to form a central chamber positioned at the center and a peripheral chamber around the central chamber; the central chamber is communicated with the peripheral chamber through a channel positioned on the peripheral wall of the central chamber; and the gas pressure in the central chamber is less than the gas pressure in the peripheral chamber. The stable-flame burner forms a static pressure chamber positioned at the center, and the gas in the static pressure chamber is depressurized and slowed, so that the flame at the central fire hole of the internal ring fire cover is stable, thereby performing the function of flame stabilization; and thus, the flame on the whole internal ring fire cover is more stable, thereby preventing the lifting flame from occurrence.

Description

technical field [0001] The invention relates to a burner. Background technique [0002] The burners of existing gas cookers are generally provided with an outer ring fire cover and an inner ring fire cover, wherein the inner ring fire cover is generally in the shape of a cylinder, and a plurality of circular fire holes are opened along the circumferential direction on the side wall of the cylinder , These fire holes generally have an included angle with the horizontal plane, and the included angle is 20-40 degrees. When this kind of burner is working, the inner ring flame is sprayed obliquely outwards, forming a ring-shaped heating ring when it contacts the bottom of the pot, so it is easy to cause uneven heating of the bottom of the pot. In addition, the inner ring gas of this burner is directly ejected from the fire hole of the inner ring fire cover without buffering, so the air velocity at the fire hole is faster, and the inner ring flame is not easy to stabilize the fla...
