Blowed premixed efficient gas burner

Technical field

The utility model relates to the burnt gas combustion device, especially for the burner of the public kitchen kitchen range that use coal gas, liquefied petroleum gas, natural gas, civil kitchen range, stove and accessory.

Background technology

The Blowed premixed gas burner basic structure of technology is by burner head now, blender, gas nozzle, blast pipe, the blast pipe air register is formed, the inner chamber of burner head is connected with blender, gas nozzle is installed in the middle of the end of mixer tube, blast pipe is connected with blender, on blast pipe, offer air register, on burner head, offer the burning fire hole of all styles of, form various heteroid burner head, its combustion gas in blender with after the air blast air mixes, transport in the burner head cavity by fire hole ejection burning, regulate a wind intake by the air register of regulating on the blast pipe, the control burning, for the stability that keeps burning, generally by the fire hole on the burner head inwardly or rotation offer and make the flame rotating percussion realize normal combustion.This class prior art all has introduction on various relevant design manual books.Prior art will be stablized the combustion gas normal combustion, the air index of necessary strict control primary air intake, be combustion gas and Air mixing ratio, when air index during greater than combustion range, promptly when intake is excessive, fiery phenomenon and imperfect combustion situation will appear taking off, hour then to produce burning insufficient when intake, and be provided with and the premix air influence by the burner head fire hole, burner is relatively poor to the versatility of various combustion gas, combustion efficiency difference or can not normal combustion use when changing combustion gas and using.This in addition burner only is suitable for open burning situation, does not have the oxygen supply of effective secondary wind when the burning situation of sealing, can not normally fully burn; Because its smooth combustion is flame self steady-flow combustion, therefore, ignition temperature is relatively low, the novel content of combustion gas fully can not being burnt

The purpose of this utility model provides a kind of simple in structure, flameholding, and highly versatile, sufficient combustion, thermal efficiency height is especially for the Blowed premixed gas burner of public kitchen kitchen range, civil kitchen range, stove and accessory use.

The utility model includes burner head 1, blender 2, gas nozzle 3, blast pipe 5, blast pipe air register 6, it is characterized in that, on the outer portion of burner head 1, evenly be distributed and be provided with some bar shaped fire holes 12, this bar shaped fire hole 12 is for upwards and the bar hole that is communicated with to side, offer secondary wind chamber 16 in burner head 1 outer end ring portion, on this secondary wind chamber 16, evenly be distributed and be provided with secondary wind venthole 17, be provided with secondary air channel 18 in secondary wind chamber 16 and 5 of blast pipes, be provided with on burner head 1 top to be connected with and be connected the burning rectifier 4 that the commutator segment 42 of the setting on the collector ring 41 constitutes by collector ring 41 and some even distributions.

The utility model is regulated a wind intake by the air register of regulating on the blast pipe 56, combustion gas in blender 2 with after the air blast primary air mixes, transport in burner head 1 chamber 10 by the 12 ejection burnings of bar shaped fire hole, bar shaped fire hole 12 makes upwards and to the smooth combustion that is implicative of each other of the flame of side, and it is big with the auxiliary air contact-making surface, bar shaped fire hole 12 is the gas flame bump collector ring 41 of peripheral direction ejection to the side, make the fully burning of combustion gas turbulent flow, and steady flame is held together in the operation that makes progress under the barrier effect of collector ring 41, the air of secondary wind venthole 17 ejections enters in the combustion zone under the cooperation of commutator segment 42, formation is the sufficient automatically auxiliary air that replenishes in the flame combustion zone, combustion gas is fully burnt, ignition temperature improves greatly, rectifier 4 thermal-arrest under high temperature action that burns simultaneously is red-hot state, not only promotes combustion gas fully to burn, and produces high temperature heat radiation, add the heat-flash transmission, can further improve the thermal efficiency.

The bar shaped fire hole 12 of the utility model burner head 1 is the sufficient automatically required air capacity of second-time burning of replenishing under the cooperation of burning rectifier 4, can be in enclosed environment normal combustion, combustion stability is good, strengthened burning, and strong to the adaptive capacity of supply gas pressure size, be subjected to primary air and combustion gas mixing scale effect little, can fully satisfy burning to different combustion gas, combustion power can be regulated in a big way by changing supply gas pressure and air demand, and application power is strong.
