Title:
FUEL REGULATING DEVICE AND FUEL REGULATING METHOD
Document Type and Number:
Japanese Patent JP2020085396
Kind Code:
A
Abstract:
To provide a fuel regulating device and a fuel regulating method capable of controlling a fuel flow rate in accordance with a calculation value and maintaining stable combustion even when outflow pressure of a flow rate regulating device is fluctuated due to any factor including fluctuation of exhaust gas pressure.SOLUTION: A fuel regulating device in the embodiment is a fuel regulating device regulating a flow rate of fuel to be supplied to a combustor and includes: a flow rate regulating section for regulating fuel supply to a predetermined flow rate; an outflow pressure measurement section acquiring outflow pressure of the fuel from the flow rate regulating section to the combustor; a pressure regulating section regulating inflow pressure of fuel to the flow rate regulating section; and an inflow pressure measurement section acquiring inflow pressure of the fuel from the pressure regulating section to the flow rate regulating section. The fuel regulating device in the embodiment further includes a control section that controls the pressure regulating section on the basis of the inflow pressure and outflow pressure so that a pressure difference between the inflow pressure and the outflow pressure becomes a predetermined bias value.SELECTED DRAWING: Figure 2
