Claims

[Scope of utility model registration request]

- A combustion air supply fan 8, a combustion air supply fan 8, and an orifice 9 located downstream of the fan 8 are provided in the flow path 6 for supplying gas to the combustion section 4, and the gas supply flow is controlled downstream of the orifice 9. A fuel gas supply passage 11 is connected to the passage 6, a zero governor 12 is provided in the fuel gas supply passage 11, and static pressure near the upstream side of the orifice 9 is applied to the zero governor 12 for its opening operation. Communication path 13
A combustion apparatus is provided with an opening/closing valve 20.23 for switching between applying and not applying static pressure for opening operation to the zero governor 12, and attaching it to the communicating path 13,
When a set time elapses after the operation of the fan 8 due to the ignition operation, the on-off valves 20 and 23 are changed from the static pressure non-applying state to the static pressure applying state, and the valves for fuel gas on the upstream side of the zero governor 12 are turned on. A combustion device characterized by being provided with a controller 22 that automatically switches a main valve 10 from a closed state to an open state.
