The other end on be fixed with an inner housing one, the inner housing one is round table-like, the microcephaly of the inner housing one of both ends open
End is located in the outer housing, and stub end stretches out outside the outer housing, and the stub end is set as mixed gas outlet, the inner casing
Flaring channel is formed along mixed gas outlet direction among body one, is additionally provided with an inner housing two, the inner casing in the outer housing
Body two includes the second conical section and the second cylindrical section, and it is tapered logical that one is constituted between second conical section and first conical section
Road constitutes a through type hybrid channel between second cylindrical section and first cylindrical section, and the inner housing one is small
Head end protrudes into second cylindrical section, the center line of the outer housing, inner housing one and inner housing two on the same line, institute
It states and is fixed with a circular ring shape combustion gas distribution housing on outer housing on the outer wall of first shell portion, the combustion gas distribution
Shell close to the junction of first conical section and first cylindrical section, the combustion gas distribution housing be equipped with combustion gas into
Mouthful, it is located in the combustion gas distribution housing on the outer housing outer wall and offers combustion gas aperture, the combustion gas aperture and described straight
General formula hybrid channel communicates.
Preferably, the taper of second conical section is greater than the taper of first conical section, and first circular cone
The taper of section is greater than the rotary table taper of the inner housing one.
Effective achievement of the invention：The configuration of the present invention is simple is reasonable, in use, air enters outer housing by air intlet
It is interior, and through type hybrid channel is flowed to along tapered channels, while combustion gas enters in combustion gas distribution housing from fuel gas inlet, and leads to
Combustion gas aperture is crossed to flow into through type hybrid channel, air is tentatively mixed in through type hybrid channel with combustion gas at this time,
And together along through type hybrid channel flow forward, mixed gas when reaching through type hybrid channel end, outer housing,
Flowing is folded under the collective effect of inner housing one and inner housing two, into inner housing two, and in the second conical section and the second circle
Flowing is folded under the collective effect of shell of column again, into inner housing one, to keep combustion gas and air further sufficiently mixed
It closes, is flowed out finally by flaring channel from mixed gas outlet, into burner.Mixing stroke is not only greatly prolonged, makes to fire
Gas and air are sufficiently mixed, and improve mixed effect, to greatly improve efficiency of combustion, and substantially reduce an oxidation in combustion product gases
The discharge of the harmful substances such as carbon, through detecting, within the scope of full load almost without carbon monoxide generation, furthermore due to structure into
It has gone reasonable design, has constituted tapered channels and flaring channel, substantially reduced stream pressure loss, energy conservation and environmental protection.
In conclusion the present invention has the characteristics that simple and reasonable, length is shorter, not only make combustion gas and air sufficiently mixed
It closes, greatly improves efficiency of combustion, reduce noxious gas emission, and substantially reduce stream pressure loss, energy conservation and environmental protection.
