装置。 Supply lines for supplying gas to multiple burner groups or burner bodies are installed in parallel, and each line is controlled proportionally via a proportional output signal according to the magnitude of the signal from a temperature sensing element that detects the temperature of the load. A proportional control valve is provided to proportionally control each burner group, and the proportional control combustion of a single burner group and the proportional control combustion of multiple burner groups are sequentially switched according to the required heat amount signal. In the spark ignition operation from either the first burner group or the second burner group, a throttle signal is given to both proportional control valves for a predetermined period of time, and then a proportional control signal is given to each proportional control valve. A combustion amount control device characterized by having a combustion amount control device.
