Claims

[Scope of utility model registration request]

The flow rate of gas supplied from the gas supply source to the main burner of the combustor through a first flow path, and the flow rate of gas supplied to the pilot burner through a second flow path branched from the first flow path. In the device to be controlled, two valves are inserted into the gas flow path from the gas supply source to the pilot burner, and two mutually independent valve actuators operated by hydraulic pressure applied from the electromagnetic pump are used to control the gas flow. A gas flow rate control device characterized in that the valves are configured to be opened and closed separately.
