出しており、燃焼状態は検出していない。In detection using such conventional methods, if the pressure difference before and after the filter is small or if the amount of change is small, it is difficult to detect incomplete combustion in advance. If you increase the pressure difference before and after the filter and increase the amount of change, the blowing function will also increase. In any case, the filter's indoor pressure is detected, and the combustion state is not detected.

C, B, premixed gas burner l - In this, the output current of the flame detection flame rod 2 provided near the combustion section is input to the current detection section 3, and the premixed gas air ratio corresponding to the output current is determined. . If the premixed gas air ratio is adjusted low or during operation, the air filter 6
It got clogged and I had to send 1! liL′! Even when jk decreases, it is similarly detected by the current detection section 3, a signal is output from the combustion control section 4, and an alarm is issued from the alarm device 5. Due to this.

することができる。8. Flame conditions of O, B, and premixed gas burners I can be detected. In Figure 2, when the air-fuel ratio of the premixed gas changes, the distance a between the flame band and the porous ceramic plate changes.From this change in flame condition, the output current value and 0.8.O, For example, it was experimentally confirmed that there is a correlation between H and the premixed gas/air ratio in the premixed gas burner l, as shown in Figure 3.For this reason, the output current value By measuring the current air-fuel ratio, the current air-fuel ratio can be detected, and a warning can be issued if there is a maladjustment during a trial run, or if the air filter is clogged.
