211st, gas inlet joint 2 221 is connected to Gas Pipe 1, Gas Pipe 2 101, Gas Pipe 1, Gas Pipe two 101 other end is connected with same fuel gas proportional control valve 102 jointly, and fuel gas proportional control valve 102 is connected with combustion gas driven opening Valve 103 is closed, combustion gas electric switching valve 103 is connected with external air supply pipe, and combustion gas electric switching valve 103 is connected with control by electric wire Device 104, controller 104 is connected to ignition electrode 105, flame monitoring pin 106, external power supply electric wire 109, exhausting by electric wire Machine rotational speed governor 121, controller 104 is by external powered by direct current；The air exhauster 14 is connected by electric wire with controller 104 Connect；The bottom land of the outer shroud firepower mixed gas distribution annular groove 12 supplies the intersection of mixed-gas channel 22 with outer shroud firepower It is provided with combustion gas and breaks up shunting post 201, walks the both sides of the combustion gas annular groove 12 of ring firepower mixed gas distribution outward；Ignition electrode 105, Flame monitoring pin 106 is fixedly connected on gas burner, igniting corresponding with the fire jetting hole of center point fire cover 3 or outer shroud point fire cover 7 And monitoring；Because center firepower is small, required combustion gas is small, and outer shroud firepower is big, and required combustion gas is more, so, center firepower supply Mixed-gas channel 21 is smaller than outer shroud firepower supply mixed-gas channel 22；During ignition, fuel gas proportional control valve 102 is twisted Knob, fuel gas proportional control valve 102, combustion gas electric switching valve 103 open pass through gas circulation, there is fire in ignition electrode 105 Flower, flame monitoring pin 106 enter monitoring state, and air exhauster 14 starts exhausting, and combustion gas respectively enters central flame by Gas Pipe 101 Power supply mixed-gas channel 21, outer shroud firepower supply mixed-gas channel 22, the air that combustion gas is taken out with air exhauster 14 is in stream Mix during logical, combustion gas is touched generation fire and burnt with spark after spraying；In combustion process, if the fire of burning is yellow or obvious Combustion gas is not good with air mixture ratio, can adjust to control 14 turns of air exhauster by the button of air exhauster rotational speed governor 121 Speed, by controlling the quickening of rotating speed/slow down to realize oxygenation or subtracting oxygen, realizes that (i.e. flame reaches most blue shape to optimal combustion state State).
