Description

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, oil liquefied gas, natural gas, civil kitchen range, stove and accessory.

Background technology

Prior art has ejection premixing type burner and Blowed premixed burner, and its difference is that the introducing supply mode of combustion gas and primary air is different.Various burners mainly are that the shape structure of burner head is different, offer the burning fire hole of all styles of on burner head, form the burner of various not isostructures and performance characteristics.This class technology all has introduction on various relevant design manual books.Prior art planform difference, the characteristics difference.But stablize the generally all strict control air intake of normal combustion, i.e. combustion gas and Air mixing ratio when air index during greater than combustion range, when promptly intake is big, not only is helpless to burning, and fiery phenomenon and imperfect combustion situation can occur taking off; Hour then to produce burning insufficient when intake, and influenced by a combustion gas fire hole setting and premix air, and burner is relatively poor to the versatility of various combustion gas, when changing combustion gas and using, and combustion efficiency difference or can not normal combustion use.Prior art also has difformity structure and device are set improving combustion efficiency on burner head for improving efficiency of combustion, but efficiency of combustion is also also imperfect.

The utility model content

The purpose of this utility model provides a kind of flameholding, and versatility is good, sufficient combustion, and thermal efficiency height is especially for the burner of public kitchen kitchen range, civil kitchen range, stove and accessory.

The utility model includes burner head 1 and premixed device---injection premixed device 5,7 or air blast premixed device 6, on burner head 1, evenly be distributed and be provided with fire hole 12, it is characterized in that, be provided with the burning rectifier of commutator segment 13 formations of some equally distributed settings on burner head 1 top, on burner head 1, be connected with outer shroud dish 2, on outer shroud dish 2, be connected with burning rectification circle 3, burning rectification circle 3 is by ring 21, the commutator segment 22 that some even distributions tilt to be connected on the ring 21 constitutes, the ring 21 of burning rectification circle 3 is fixedlyed connected with the outer shroud dish 2 of burner head 1, offers into secondary intake opening 20 on outer shroud dish 2.

The utility model combustion gas and primary air are mixed in burner head 1 inner chamber through premixed device, combustion gas is provided with fire hole 12 ejection burnings by evenly being distributed on the burner head 1, gas flame bump burning rectifier rectification sheet 13 makes the combustion gas turbulent flow, fully contact, combustible gas is fully burnt with airborne oxygen.The drainage that matches with commutator segment 13 of burning rectification circle 3, the flame impingement turbulent flow is contacted with the airborne oxygen of secondary wind, burning rectification circle 3 draws flame in and forms the eddy current rotation, the combustion zone prolongs, the flame flow velocity is accelerated, fully improve efficiency of combustion, the pressure reduction that produces along with the size that sprays gas quantity and flame intensity changes, drainage intensity also changes thereupon automatically, formation is sufficient automatically required air and the oxygen of second-time burning that replenishes in flame zone, combustion gas is fully burnt, ignition temperature and efficient improve greatly, commutator segment 13 and rectification circle 3 thermal-arrest under high temperature action are red-hot state simultaneously, not only promote combustion gas fully to burn, and produce the high temperature heat radiation effect, add the heat-flash transmission, can further improve the thermal efficiency.

The utility model burner head combustion stability under

commutator segment

13 and 3 mating reactions of rectification circle is good, has strengthened burning, and is strong to supply gas pressure size and combustion gas quality adaptive capacity, is subjected to primary air and the scale effect of combustion gas premix little, and adaptive capacity is strong, and is easy to operate.
