The existing burner generally adopts a plurality of ejector pipes to supply air to different flame rings. However, the air inlets of the ejector pipes may have a problem of small distance between each other, and the small distance between the air inlets may cause negative pressure interference during operation of the burner, thereby affecting the ejector performance, resulting in weak wind resistance and flame quenching risk. In addition, in the base of the partial combustor, fuel gas firstly enters through the injection pipe and sequentially passes through the gas mixing chambers of the rings, then gradually rises to the annular distribution air passages from the gas mixing chambers, and finally flows out from the fire outlet holes of the fire cover. Therefore, the gas path for the gas to flow is longer, and the number of the gas passing through the curve (especially the right-angle curve) is more, so that the gas flow resistance is overlarge, and the combustion efficiency is lower.

The utility model provides a combustor, as seen from fig. 1 to fig. 3, this combustor includes:

the base 2 comprises an outer ring seat 21 and an outer injection pipe 22, the outer ring seat 21 comprises an outer ring seat inner peripheral wall 211, an outer ring seat outer peripheral wall 212 and an outer ring distribution air passage 213 formed between the outer ring seat inner peripheral wall 211 and the outer ring seat outer peripheral wall 212, the outer ring distribution air passage 213 is in an annular groove shape and is provided with a top annular opening, the outer injection pipe 22 horizontally extends out from the outer ring seat inner peripheral wall 211, and an outlet of the outer injection pipe 22 is horizontally communicated with the outer ring distribution air passage 213; and

The outer injection pipe 22 comprises a first outer injection pipe and a second outer injection pipe which are arranged in parallel at intervals, and the first outer injection pipe and the second outer injection pipe are symmetrically arranged relative to a diameter line passing through the circle center of the outer ring seat 21. The technical personnel in the field know that the length of drawing the pipe as far as possible extension draws can promote the inside gas circulation's of drawing the pipe kinetic energy, and then improves and draw the penetrating performance who draws the pipe. Therefore, the first outer injection pipe and the second outer injection pipe are usually arranged at the positions close to the diameter line of the circle center of the outer ring seat 21, so that the injection lengths of the two outer injection pipes 22 are closer to the diameter length of the circle center of the outer ring seat 21, the design length is longer, and the injection capacity of the two outer injection pipes 22 can be ensured.

Referring to fig. 5, the outer ring distribution air passage 213 includes a first half ring distribution air passage 213a communicated with the air flow outlet of the first outer injection pipe, a second half ring distribution air passage 213b communicated with the air flow outlet of the second outer injection pipe, and an air passage blocking portion 213c disposed between the air flow outlet of the first outer injection pipe and the air flow outlet of the second outer injection pipe to block the first half ring distribution air passage and the second half ring distribution air passage. Wherein, the outer ring gas duct inlet includes a first outer ring gas duct inlet 213d and a second outer ring gas duct inlet 213e, and a gas duct blocking portion 213c is provided between the first outer ring gas duct inlet 213d and the second outer ring gas duct inlet 213e, so that the outer ring distribution gas duct 213 is divided into a first semi-ring distribution gas duct 213a communicating with the first outer ring gas duct inlet 213d and a second semi-ring distribution gas duct 213b communicating with the second outer ring gas duct inlet 213 e.

The utility model discloses an in the combustor, see fig. 5 and fig. 7, the combustor draws including the center and penetrates pipe 23 and inner ring fire lid 3, and the center draws to penetrate pipe 23 and draws to penetrate pipe 22 opposite with outer drawing from the air flue blocking part towards inside extension of centre of a circle level of outer ring seat 21, and base 2 is still including connecting in the center draw penetrate the inner ring seat 24 of the air outlet end of pipe 23, and 3 covers on inner ring seat 24 of inner ring fire lid buckle. The opening directions of the central injection pipe 23 and the outer injection pipe 22 are opposite, so that negative pressure interference between primary air and the outer injection pipe can be prevented when the primary air enters the injection pipes to be mixed, the primary air entering amount is increased, and the combustion performance is improved.

Similarly, in the base 2, the lowest point of the outer peripheral wall of the central injection pipe 23 is not lower than the lowest point of the bottom surface of the bottom wall of the outer ring distribution air passage 213, and the central injection pipe 23 can be generally positioned on the same plane with the outer injection pipes 22 on both sides, so that the overall ultra-thin design of the base 2 is satisfied.
