Abstract (en)
[origin: EP3406973A1] Provided is a fuel supply system (100) including a fuel gas supply header (102) through which fuel gas supplied from an LNG tank (400) flows; a main nozzle supply pipe (54); a pilot nozzle supply pipe (55); a control valve (53) provided to the main nozzle supply pipe (54); and a control unit (90) that controls the degree of opening of the control valve (53). The control unit (90) controls the control valve (53) so that when the flow rate of the fuel gas supplied from the fuel gas supply header (102) to the first burner (221) is less than a predetermined flow rate, the control valve (53) is closed, and when the flow rate of the fuel gas supplied from the fuel gas supply header (102) to the first burner (221) is greater than or equal to the predetermined flow rate, the degree of opening of the control valve (53) increases with an increase in the flow rate of the fuel gas.
