Fuel oil supply device

Abstract

The present disclosure relates to a fuel oil supply device for supplying fuel oil to a combustor of a gas turbine. The fuel oil supply device is provided with: a pump for supplying fuel oil; a supply pressure control valve disposed downstream of the pump and used for controlling the pressure of the fuel oil supplied by the pump; and a plurality of flow rate controlling valves disposed downstream of the supply pressure regulating valve and used for controlling the flow rates of the fuel oil supplied to a plurality of fuel nozzles provided in a combustor. Further, a plurality of cavitation suppressing parts are provided downstream of the plurality of flow rate controlling valves. The openings of the flow rate regulating valves are controlled on the basis of the first pressure of the fuel oil upstream of the flow rate controlling valves, the second pressure of the fuel oil downstream of the flow rate controlling valves, and the flow rates of the fuel oil supplied to the fuel nozzles.
