a steady flame burner

Abstract

A stable flame burner, comprising a base, an inner ring air mixing chamber and an outer ring air mixing chamber arranged on the base, an inner injection pipe communicating with the inner ring air mixing chamber and an outer ring air mixing chamber The outer injection tube, the inner ring fire cover and the outer ring fire cover, the top surface of the inner ring fire cover is provided with a central fire hole in the center and a peripheral fire hole around the center fire hole, the inner ring fire cover The air flow channel between the inner injection tube is separated to form a central chamber located in the center and a peripheral chamber surrounding the central chamber, and the central chamber and the peripheral chamber are separated by a wall located on the peripheral wall of the central chamber. The channels are connected, and the pressure of the gas flow in the central chamber is lower than the pressure of the gas flow in the peripheral chambers. The flame-stabilizing burner forms a static pressure chamber located in the center, and decompresses and decelerates the airflow in the static pressure chamber, thereby stabilizing the flame of the central fire hole of the inner ring fire cover and playing the role of stabilizing the flame, making the whole The flame of the inner ring fire cover is more stable to prevent the occurrence of misfire.

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...
