Abstract

An assembly for creating a fire display from a liquid fuel comprises a fuel receiving reservoir connected to a burner by a conduit, the conduit providing a flow channel for a liquid fuel from the reservoir to the burner. When a container of liquid fuel is placed in a bottle receiving tray the fuel is dispensed into the reservoir and in turn flows into the burner. Flammable vapors over the liquid fuel in the burner can then be ignited. The arrangement provides a continuous feed of fuel to the burner and allows safe replacement of the fuel container and replenishment of the fuel in the burner while the flame is present.

Claims (17)

1. An assembly for creating a fire display from a liquid fuel comprising:

a) one or more fuel receiving reservoirs connected to one or more burners by one or more conduits, the conduits providing flow channels from said one or more reservoirs to said one or more burners for liquid fuel contained in said reservoirs, the fuel receiving reservoirs and the burners being spaced apart and positioned to provide equal fuel levels in the reservoir and burner,

b) a bottle receiving tray configured to receive a container of liquid fuel, and

c) a container of liquid fuel,

the bottle receiving tray positioned at a suitable distance from the burner to allow addition of liquid fuel to the system without ignition thereof by the flames constituting the fire display during said addition and to provide delivery of the liquid fuel in the container to the fuel receiving reservoir upon placement of the container in or on the bottle receiving tray, said bottle receiving tray including a piercing element, and the container of the liquid fuel having a sealed access port, such that placement of the container in or on the bottle receiving tray causes the piercing element to penetrate the sealed access port.

2. The assembly of claims 1 wherein said bottle containing the liquid fuel is designed for placement in or on the bottle receiving tray with an access port positioned over the piercing element with said piercing element oriented to puncture the sealed access port on the bottle so as to dispense the liquid fuel in the bottle into the fuel receiving reservoir, said fuel in turn flowing through the conduit and into the burner.

3. The assembly of claim 1 further including two or more noncombustible logs mounted on top of the burner, a first noncombustible log positioned on a rearward portion of, and extending across a width of the burner and a second noncombustible log positioned on a forward portion of the burner, said first noncombustible log removably covering the bottle receiving tray and the bottle positioned in the bottle receiving tray.

4. The assembly of claim 1 wherein the liquid fuel comprises an ester oil, plant oil, alcohol, paraffinic compositions or petroleum product.

5. The assembly of claim 1 wherein the liquid fuel is an alcohol solution.

6. The assembly of claim 1 wherein the liquid fuel is denatured ethanol.

7. The assembly of claim 1 wherein the burner has at least a portion of a bottom surface thereof that is disposed at a point lower than the remainder of the bottom surface to provide a fuel well.

8. The assembly of claim 1 including more than one burner wherein at least one burner is configured so that the liquid fuel contents thereof dissipates prior to one or more of the other burners.

9. The assembly of claim 1 wherein the bottle receiving tray comprises a bottle receiving tray.

10. The assembly of claim 1 wherein the one or more burners comprise a liquid fuel burner assembly wherein one or more burners therein have at least a portion of a bottom surface thereof that is disposed at a point lower than the remainder of the bottom surface to provide a fuel well.

11. The assembly of claim 10 for creating a fire display the assembly comprising one or more burners and one or more fuel receiving trays, one or more containers of a liquid fuel positioned in said one or more fuel receiving trays, said one or more fuel receiving trays and containers for fuel positioned therein covered by an openable fire retardant enclosure.

12. The assembly of claim 11 wherein said openable fire retardant enclosure is an artificial log.

13. The assembly of claim 1 for creating a fire display, the assembly comprising one or more burners and one or more fuel receiving trays, one or more containers of a liquid fuel positioned in said one or more fuel receiving trays, said one or more fuel receiving trays and containers for fuel positioned therein covered by an openable fire retardant enclosure.
