Semiorbicular second steam line, second steam line of every layer and every layer of protection it is additionally provided with outside every layer of protective cover
The inlet end connection of the igniter 14 outside cover thinks that it supplies.It is additionally provided with for fixed ignition device 14 outside every layer of protective cover
Lock solid structure 15, lock solid structure 15 one end is fixed on protective cover, and the other end is fixing with igniter 14 to be connected.The present embodiment
In, each igniter 14 utilizes two lock solid structures 15 to fix, and in other embodiments, lock solid structure 15 can also be other
Number.
Refer to Fig. 4, igniter 14 includes ignition structure 32, thermocouple 34 and lighter 36, and ignition structure 32 sets
Put the fixed structure 38 in order to igniter 14 to be fixed on injection type burner, thermocouple 34 and the fixing peace of lighter 36
It is loaded on fixed structure 38.Wherein thermocouple 34 is electrically connected with the master control system of injection type burner, and thermocouple 34 is used
To detect the temperature of ignition structure 32, and by the Temperature Feedback that records to master control system, if it is unsuccessful to light a fire, thermocouple 34 does not has
Temperature being detected, or the temperature detected is not reaching to preset value, master control system can have soon found that, in order to locates in time
Reason.Lighter 36 is in order to light ignition structure 32.
In an illustrated embodiment, ignition structure 32 is the second venturi burner 32, and the second venturi burner 32 wraps
Including Venturi tube 40 and flame holder 44, Venturi tube 40 has inlet end 46 and outlet side 48, and flame holder 44 is arranged on outlet side
48。
Every layer of protective cover is provided with the opening 50 corresponding with the second venturi burner 32 position.Venturi tube 40 is managed in it
Hold with it and bend towards the first venturi burner 10, so that the flame holder 44 of the second venturi burner 32 is near right with it
The gas outlet 52 of the one first venturi burner answered, specifically, it is right that the bending part of the second venturi burner 32 stretches into
Opening 50 is answered to think one first venturi burner ignition of correspondence.
The lower end of the second venturi burner 32 is provided with semiorbicular second steam line 33, the second venturi burner 32
Inlet end and the second steam line 33 connect, the second steam line 33 in order to provide combustion gas to the second venturi burner 32,
Also function to the fixing effect supporting the second venturi burner 32 simultaneously.
In an illustrated embodiment, lock solid structure 15 is fixing with Venturi tube 40 is connected.Specifically, two lock solid structure 15
One of them is fixedly attached to the lower edge of Venturi tube 40 bending part, and another lock solid structure 15 is fixedly attached to Venturi tube
40 positions on the lower, thus igniter is securely fixed.
Fixed structure 38 is a flange 38, and flange 38 is fixed at the upper limb of Venturi tube 40 bending part, and flange 38
It is perpendicularly fixed on flange 38 with the pipe shaft upper vertical of Venturi tube 40, thermocouple 34 and lighter 36.Thermocouple 34 has
Induction end 54, induction end 54 is disposed in proximity to the position of the second venturi burner 32 flame holder 44 to feel its temperature
Should, lighter 36 has an ignition burner 56 towards flame holder 44, ignition burner 56 just to flame holder 44 port of export with to it
Light a fire.
Flame holder 44 top and the Venturi tube 40 pipe shaft lower end of the second venturi burner 32 are provided with some apertures.Wherein
It is to increase flame holder 44 blockage ratio that flame holder 44 top arranges aperture 58 so that it is the whirlpool yardstick formed increases, big whirlpool
The time that comes off is elongated, gives the ignition time that unburned mixture body is enough, strengthens combustion stability, and being conducive to is the first venturi
Burner ignition；Aperture 60 is set in Venturi tube 40 pipe shaft lower end in order to absorb air mixed combustion, increases air-fuel ratio, it is ensured that
Combustion gas is fully burnt.
In sum, the present invention provides the igniter of a kind of injection type burner, and this igniter is arranged on protection
The outside of cover, igniter includes ignition structure, thermocouple and lighter, and ignition structure arranges a fixed structure, thermocouple
And lighter is fixed on fixed structure, thermocouple is in order to detect the temperature of ignition structure, and the Temperature Feedback that records is given main
Control system, if it is unsuccessful to light a fire, thermocouple is not detected by temperature, and master control system can have soon found that, in order to processes in time,
Lighter is in order to light ignition structure.By igniter is arranged at outside protective cover, it is to avoid thermocouple is because of distance flame
Too closely toasted and reduction of service life, ensured that ignition structure, thermocouple and lighter are installed concentratedly simultaneously, easy for installation,
Reliability is high, reduces cost.
Concepts described herein may be embodied to other form in the case of without departing from its spirit and characteristic.Disclosed
Specific embodiment should be considered exemplary rather than restrictive.Therefore, the scope of the present invention is by appended claim,
Rather than be determined according to these descriptions before.Any change in the letter and equivalency range of claim is all
The scope of these claim should be belonged to.
