Efficient combustor

Abstract

The invention relates an efficient combustor. The efficient combustor comprises an inner ring fire cover, the inner ring fire cover comprises an inner ring fire cover body and a cover body, an inner ring fire hole is formed in the edge of the upper end of the inner ring fire cover body in the circumferential direction, an inner ring gas mixing cavity is formed by the inner cavity of the inner ringfire cover body corresponding to the inner ring fire hole, the inner ring fire cover body at the lower part of the inner ring gas mixing cavity is provided with gas mixing channels which penetrate upand down, the number of the gas mixing channels is matched with inner ring ventilation openings, each gas mixing channel is correspondingly arranged on the corresponding inner ring ventilation openings, so that the gas mixing channels are in communication with the inner ring ventilation openings and the inner ring gas mixing cavity respectively. According to the efficient combustor, the gas mixing channels are arranged and correspondingly in communication with the inner ring ventilation openings and the inner ring gas mixing cavities through the gas mixing channels, so that the air and the fuel gas can be fully mixed in each gas mixing channels, enters the gas mixing cavity for re-mixing, so that the air and the fuel gas can be sufficiently and efficiently combusted in the inner ring firehole after the air and the fuel gas are fully combusted.

Description

technical field [0001] The invention relates to the field of gas stoves, in particular to a high-efficiency burner. Background technique [0002] The gas burner includes a base, a gas mixing chamber, an outer ring fire cover and an inner ring fire cover, wherein the gas mixing chamber is set above the base, and the outer ring fire cover and the inner ring fire cover are respectively set above the gas mixing chamber . Among them, the outer ring fire cover is generally ring-shaped, including an annular top wall, an inner ring wall and an outer ring wall extending vertically downward or obliquely downward from the inner and outer sides of the annular top wall, and the annular top wall 1. The inner ring wall and the outer ring wall are surrounded to form a gas mixing chamber, and the outer ring wall is provided with an outer ring fire hole. The inner ring fire cover generally includes a cylindrical base and a cover body covering the base, and the cover body is provided with an...
