Abstract
The utility model discloses an upper air intake combustor. The technical scheme is that a gas passage and a gas nozzle are arranged on a bottom cup, a furnace head is arranged on the bottom cup, a baffle plate is arranged between the furnace head and the bottom cup, a burnercap is placed on the furnace head, and a main flame hole is formed on the burnercap; and a flameout prevention device is arranged on the upper air intake combustor, the flameout prevention device comprises a flameout prevention groove formed below the main flame hole, the flameout prevention groove is communicated with the gas passage, and a communication hole with the gas output less than the main flame hole is formed between the flameout prevention groove and the gas passage. In the utility model, the communication hole with the gas output less than the main flame hole is formed between the flameout prevention groove and the gas passage, so as to ensure the gassing pressure of the flameout prevention groove is relatively less and the flame does not depart from the flameout prevention groove; and when the pressure of the gas jetted by the main flame hole in the combustor is overlarge, the flame departs from the main flame hole, and the flame in the main flame hole is burned out, the flame in the flameout prevention groove can light the flame in the main flame hole again, thereby ensuring the safety of the combustor.
Description
Technical field:
The utility model relates to a kind of upper inlet wind type burner.
Background technology:
At present, various upper inlet wind type burner structures are numerous.A kind of " going up the air intake multi-injector burner " just disclosed for No. 200820088582.3 as Chinese patent, should go up the air intake multi-injector burner, blast tube and at least two gas nozzles are arranged on the end cup, burner is placed on the end cup, be provided with dividing plate between burner and end cup, be placed with the fire lid on the burner, be provided with fire output hole between burner and fire lid, burner comprises outer shroud burner and interior ring oven head, and outer shroud burner and interior ring oven head are respectively equipped with corresponding outer shroud nozzle and interior ring spray mouth.The air inlet pipe of outer shroud nozzle and interior ring spray mouth is connected, and fixedlys connected between fire lid and burner.But have the following disadvantages: when the pressure of said burner master fire output hole ejection combustion gas is excessive, the phenomenon that flame leaves combustion gas master fire output hole can occur, at this moment, under the situation that burnt gas switch is opened, be easy to occur fray-out of flame, cause serious potential safety hazard.
Summary of the invention:
The purpose of this utility model is: provide a kind of and can effectively prevent from flame, a kind of upper inlet wind type burner safe in utilization.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of upper inlet wind type burner, blast tube and gas nozzle are arranged on the end cup, burner is placed on the end cup, be provided with dividing plate between burner and end cup, be placed with the fire lid on the burner, fire covers and is provided with main fire output hole, it is characterized in that: described upper inlet wind type burner is provided with anti-from flame device, anti-ly comprise: be located at the anti-of main fire output hole below, anti-ly be connected the anti-intercommunicating pore that between flame groove and blast tube, is provided with less than main fire output hole gas output with blast tube from the flame groove from the flame groove from flame device.
Advantage of the present utility model is: because the anti-intercommunicating pore that is provided with between flame groove and blast tube less than main fire output hole gas output, it can make, and anti-to go out atmospheric pressure from the flame groove less relatively, and assurance flame can not leave anti-from the flame groove.Excessive when the pressure of burner master fire output hole ejection combustion gas, flame leaves main fire output hole, and when main fire output hole fray-out of flame occurring, anti-flame in the flame groove can be lighted main fire output hole flame once more, has guaranteed the security performance of burner.
In the utility model, described upper inlet wind type burner is provided with at least two gas nozzles, burner comprises outer shroud burner and interior ring oven head, outer shroud burner and interior ring oven head are respectively equipped with corresponding outer shroud nozzle and interior ring spray mouth, the air inlet pipe of outer shroud nozzle and interior ring spray mouth is connected, and main fire output hole place studs with the copper alloy circle of fusing point greater than 700 degree on the burner.Because main fire output hole place studs with the copper alloy circle of fusing point greater than 700 degree on the burner, even make burner of the present utility model under the situation of tempering, the material of main fire output hole can not melt yet, and the fire hole size can not change, thereby avoided danger, improved the security performance of burner.
In the utility model, the axis direction of described main fire output hole and the angle of horizontal direction are 15 degree.It can make flame be close to the bottom of a pan, guarantees that simultaneously combustion gas mixes with air fully, improves the thermal efficiency of burner.
In the utility model, described interior ring oven head height is in the outer shroud burner.It can make flame transmit smoothly between inner and outer ring.Simultaneously, can save similar burner and be located at the straight-line transmitting fire groove that fire covers, make the fire lid be not easy distortion, improve the security performance of burner.
Description of drawings:
Fig. 1 is the utility model exploded sketch.
Fig. 2 is the utility model external structure schematic diagram.
Fig. 3 is the utility model generalized section.
The specific embodiment:
In conjunction with Fig. 1, Fig. 2, shown in Figure 3: the upper inlet wind type burner of present embodiment, blast tube 2 and gas nozzle 3 are arranged on the end cup 1, burner 4 is placed on the end cup 1, is provided with dividing plate 5 between burner and end cup, is placed with fire lid 6 on the burner 4, and fire lid 6 is provided with main fire output hole 7.Described upper inlet wind type burner is provided with anti-from flame device, anti-ly comprise from flame device: the annular of being located at main fire output hole below is anti-from flame groove 8, anti-ly be connected with blast tube 2, anti-ly be provided with intercommunicating pore 9 less than main fire output hole gas output from flame groove 8 and 2 of blast tubes from flame groove 8.
The upper inlet wind type burner of present embodiment is provided with at least two gas nozzles 3, burner comprises outer shroud burner and interior ring oven head, outer shroud burner and interior ring oven head are respectively equipped with corresponding outer shroud nozzle and interior ring spray mouth, the air inlet pipe of outer shroud nozzle and interior ring spray mouth is connected, and main fire output hole place studs with the copper alloy circle of fusing point greater than 700 degree on the burner.The axis direction of main fire output hole 7 and the angle of horizontal direction are 15 degree.It can make flame be close to the bottom of a pan, guarantees that simultaneously combustion gas mixes with air fully, improves the thermal efficiency of combustion gas.The ring oven head height is in the outer shroud burner in described.It can make flame transmit smoothly between Internal and external cycle.
Because the anti-intercommunicating pore that is provided with between flame groove and blast tube less than main fire output hole gas output, it can make, and anti-to go out atmospheric pressure from the flame groove less relatively, and assurance flame can not leave anti-from the flame groove.Excessive when the pressure of burner master fire output hole ejection combustion gas, flame leaves main fire output hole, and when main fire output hole fray-out of flame occurring, anti-flame in the flame groove can be lighted main fire output hole flame once more, has guaranteed the security performance of burner.
