FUEL FLOW CONTROL DEVICE FOR OIL COMBUSTOR BURNER

摘要

PROBLEM TO BE SOLVED: To prevent incomplete combustion by preventing an increase in spray quantity from a return type pressure spray nozzle even when a discharge quantity drops owing to a secular cause in an electromagnetic pump in an advance line, in a fuel flow control device for an oil combustor burner using a return type pressure spray nozzle. SOLUTION: The fuel flow control device for an oil combustor burner using the return type pressure spray nozzle has in a return line a flow regulating valve driven by valve opening time control based on a duty ratio for varying a pulse width. A spray quantity from the spray nozzle can be thus prevented from increasing to prevent incomplete combustion. COPYRIGHT: (C)2003,JPO
