This assembly includes a spark plug igniter unit, a liquid fuel system, an air distribution system, a housing enclosing the components and a vaporization subassembly disposed within the housing for changing liquid fuel to vapor fuel.
Claims9
A liquid pilot assembly for use in a fuel pit for igniting combustible fuel in the pit comprising:
- a housing forming a chamber for retaining a mixture of liquid fuel and water, the chamber containing an upper ignition zone for receiving a mixture of ambient air and fuel vapor produced from the liquid fuel;
- an igniter unit means located in the chamber and adjacent to the ignition zone for providing as required electronically igniting of the fuel vapor in the ignition zone;
- a fuel system means for supplying said liquid fuel to the chamber;
- and
- a vaporization subassembly comprising an air distribution system for continuously supplying compressed air to prevent the ambient air and fuel vapor mixture from becoming too rich, assisting in the changing of liquid fuel to fuel vapor and for swirling the fuel vapor from the fuel in the ignition zone.
