In a typical combustion range (3000 to 1000 kcal/h), the ion current value Xf has a distribution with a peak approximately at an air ratio = 0.8 to 0.9. Therefore, by adjusting the pump driving frequency and determining the amount of fuel supplied so that the ion current value If becomes the maximum value, air ratio control is performed to maintain a stable combustion state.

In addition, fuel is supplied from the fuel tank 5 to the fuel nozzle/L by the fuel pump 6.
/7 and is supplied to the carburetor 8 through the air vent 10, vaporized and mixed in the carburetor 8 with combustion air supplied from the blower fan 9 through the air port 10, and passed through the mixing plate 11 to the burner as premixed gas. 1 to form a combustion flame 12. 1

A part of the combustion air flows through the air branch 15 through the blower fan 9 and is supplied to the burner 1.

を示す。In the above configuration, the fuel and air ejected from the fuel nozzle V7 and the air port 10 become premixed gas in the heated vaporizing cylinder 8, pass through the mixing plate 11, flow out of the rectifier cylinder 2, and flow into the rectifier space 3. After that, a flame 12 is formed on the surface of the combustion wire mesh 4. At this time, the temperature measuring junction 14 of the thermocouple 13 is located about 3 degrees inward from the rectifier cylinder 2.
Since they are spaced apart by ~5 mm, the temperature output signal measures the radiant heat from the rectifier tube 2 and the temperature of the premixed gas. Here, FIG. 2 shows the relationship between the ratio of combustion air to fuel, that is, the air ratio λ, and the electromotive force Ev of the thermocouple 13. The electromotive force Ev due to the radiant heat from the straightening tube 2, which is affected by the combustion wire mesh 4 and the flame 12 formed on its surface and is at a high temperature, reaches its peak when the air ratio λ=1.0 and the flame temperature reaches its maximum value. It is thought that it will be destroyed. (Indicated by a broken line.) On the other hand, the premixed gas temperature shows a large value on the low air ratio side.

制御性が良くなる。(-Indicated by a dotted chain line.) By the way, in this example,
Since the temperature measuring junction 14 is located at a distance of about 3 to 5 B inward from the rectifier tube 2, the influence of radiant heat from the rectifier tube 2 is not so great, and the influence of the temperature of the premixed gas is large. Therefore, as shown by the solid line, the electromotive force Ev of the thermocouple 13 peaks at the air ratio λ = 1.0, rapidly decreases on the high air ratio side (λ 1.0), and decreases rapidly on the low air ratio side (λ < 1). .0>, it does not decrease at all.Therefore, the air ratio λ is adjusted so that the electromotive force is set to an appropriate value, for example, a value such that E v = a.
By adjusting λ, it becomes possible to control the air ratio to around λ=1.5. Therefore, if the electromotive force Ev is lower than the set value a, it is recognized that the air ratio is small, and the amount of fuel supplied by the pump 6 is reduced in order to adjust the air ratio to a higher side. Further, when the electromotive force Ev is smaller than the set value a, the air ratio is large, and the amount of fuel supplied by the pump 6 is increased in order to adjust the air ratio to a lower side. In this way, the fuel supply amount is controlled so that the electromotive force Ev always remains at a constant value, and the air ratio can be controlled to an arbitrary set value (for example, around λ=1.5). Further, in this embodiment, the air ratio control is performed by adjusting the pump 6, but the air ratio control can be similarly performed by adjusting the air supply amount of the blower fan 9. Furthermore, since the ambient temperature at the temperature measuring junction 14 is relatively low, approximately 400°C or less, it is possible to use copper/constance (C, C) as the type of thermocouple 13, which is Since a large electromotive force can be obtained, the slope of the thermocouple 13 relative to the air ratio becomes steeper, and the variation in air ratio control is reduced.
Improves controllability.

くなる。On the other hand, in this embodiment, the path of the thermocouple 17 is provided in the air branch path 19 and is used together with the path of combustion air, so the temperature of the upper part of the burner 1 is cooled by the combustion air and the upper part of the burner 1 is excessively cooled. In addition to making it difficult for the flashback phenomenon to occur, pressure is applied in the air branch path 19, so there is no leakage of the premixture and the iV! +l couple 17
There is also no risk of premixture leakage due to insertion of the fuel into the burner 1.
