Methods and apparatus to regulate a gaseous fuel system

Abstract

Systems, apparatus, and methods to a flame out valve for a gaseous fuel system are disclosed. An example apparatus to reduce fuel combustion comprises: a first valve connected to a fuel supply line, the first valve including: a first plug to control a flow of fuel; a first spring coupled to a first end of the first plug; and a first magnet coupled to a second end of the first plug; a second valve connected to a purge system in parallel with the fuel supply line, the second valve including: a second plug to control a flow of a gas; a second spring coupled to a first end of the second plug; and a second magnet coupled to a second end of the second plug, the second magnet magnetically coupled to the first magnet; and an electromagnetic actuator coupled to at least one of the first or the second valve.
