Description
Technical field
The utility model relates to burnt gas combustion device, especially for using public kitchen kitchen range, the civil kitchen range of coal gas, liquefied petroleum gas, natural gas, the burner of stove and accessory.
Background technology
The basic structure of the Blowed premixed gas burner of prior art is made up of burner head, mixer tube, gas nozzle, blast pipe. In burner head, offer the burning fire hole of all styles of, form various heteroid burner head. The inner chamber of burner head is connected with mixer tube, and gas nozzle and blast pipe are mounted on the outer end of mixer tube, offers air register on blast pipe. After combustion gas mixes with air blast air in mixer tube, transport in burner head cavity by burning fire hole ejection burning, by regulating the air register on blast pipe to regulate a wind intake, control combustion.
Above-mentioned have technology now, for reaching the well-mixed object of air and combustion gas, need to have longer mixer tube, and mixer tube length is large, and gas burner volume is increased, and greatly limited installing and using of burner.
And, stablize combustion gas normal combustion, must strictly control the air index of primary air intake, it is the mixing ratio of combustion gas and air, in the time that air index is greater than combustion range, in the time that intake is excessive, just there will be de-fiery phenomenon and imperfect combustion situation, when intake, hour to produce burning insufficient, and be subject to the impact of burner head burning fire hole setting and premix air, burner is poor to the versatility of various combustion gas, and when changing combustion gas and using, combustion efficiency is poor or can not normal combustion use.
This burner is only suitable for open burning situation in addition, in the time of the burning situation of sealing, there is no effective Secondary Air oxygen supply, can not normally fully burn. Because its smooth combustion is flame self steady-flow combustion, therefore, ignition temperature is relatively low, combustion gas fully can not be burnt.
