摘要

A steam and fuel oil supply and purge valve has a steam valve and actuator member which provides for a closed position, a purge operation with communication established between a steam supply line and a discharge line leading to an oil burner, a burner operation position wherein the actuator portion of the member engages and opens an oil supply valve member and thus establishes communication between an oil supply line and an oil discharge line to the burner. Oil recirculation is also provided together with a "cooling" steam feature. The latter is provided by the steam valve and actuator at an additional position where a metered flow of "cooling" steam is provided for inoperative burner tips when other burners remain in operation.
