Through setting up mixing chamber 230, the cavity space of furnace end 200 can make full use of, the gas draws the pipe 221 and the outer loop to draw the play back entering mixing chamber 230 of the end of giving vent to anger of pipe 222 from the middle ring to carry to middle ring outlet channel 211 and outer loop outlet channel 212 after further intensive mixing with the air in mixing chamber 230, prolonged the flow path of gas from this for gas and air mixing are more even, and then can improve combustion efficiency.

It is understood that the middle ring injection pipe 221 and the outer ring injection pipe 222 may be integrally formed with the peripheral wall of the mixing chamber 230, and the inner ring injection pipe 220 may also be integrally formed with the inner ring air outlet passage 210. The present invention is not particularly limited.

Referring to fig. 7 to 12, in some embodiments of the second aspect of the present invention, the mixing chamber 230 is provided with a partition plate, the partition plate divides the mixing chamber 230 into a middle ring mixing chamber 231 and an outer ring mixing chamber 232, the middle ring mixing chamber 231 communicates with the middle ring outlet passage 211 and the middle ring ejector pipe 221, and the outer ring mixing chamber 232 communicates with the outer ring outlet passage 212 and the outer ring ejector pipe 222. In the above structure, the middle ring mixing cavity 231 can fully mix the gas and the air input by the middle ring ejector pipe 221 and then deliver the gas and the air to the middle ring gas outlet channel 211, and the outer ring mixing cavity 232 can fully mix the gas and the air input by the outer ring ejector pipe 222 and then deliver the gas and the air to the outer ring gas outlet channel 212. Therefore, the conveying path of the fuel gas can be prolonged, the fuel gas and the air are mixed more uniformly, and the combustion efficiency can be improved.

Referring to fig. 12, in some embodiments of the second aspect of the present invention, the middle ring exhaust channel 211 and the outer ring exhaust channel 212 are disposed on the periphery of the inner ring exhaust channel 210, the middle ring mixing cavity 231 and the outer ring mixing cavity 232 are respectively located on two sides of the inner ring exhaust channel 210, the exhaust end of the middle ring ejector pipe 221 extends into the middle ring mixing cavity 231, and the exhaust end of the outer ring ejector pipe 222 extends into the outer ring mixing cavity 232. Therefore, all the fuel gas in the middle ring injection pipe 221 can be conveyed to the middle ring mixing cavity 231; the gas in the outer ring ejector 222 can be completely delivered to the outer ring mixing chamber 232.

It will be appreciated that, with reference to fig. 12, the intermediate ring mixing chamber 231 is located partially between the outer peripheral wall of the intermediate ring ejector pipe 221 and the inner ring outlet passage 210, and the outer ring mixing chamber 232 is located partially between the outer peripheral wall of the outer ring ejector pipe 222 and the inner ring outlet passage 210. In the above structure, the gas flows out from the middle ring injection pipe 221 and then flows into the middle ring gas outlet passage 211 through the middle ring mixing cavity 231 between the outer peripheral wall of the middle ring injection pipe 221 and the inner ring gas outlet passage 210, and the gas flows out from the outer ring injection pipe 222 and then flows into the outer ring gas outlet passage 220 through the outer ring mixing cavity 232 between the outer peripheral wall of the outer ring injection pipe 222 and the inner ring gas outlet passage 210, so that the flow paths of the gas in the middle ring mixing cavity 231 and the outer ring mixing cavity 232 can be further increased, and the gas and the air are mixed more uniformly and sufficiently.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
