Abstract
A fire display assembly has a burner tray optionally located within a hollow space in the interior of a non-flammable structure. A porous element on or in the non-flammable structure has extensions from a lower surface thereof extending into fuel in the burner tray. The assembly can include a fuel tray connected to the burner tray by conduits which provide flow channels for liquid fuel between the trays. When a container of liquid fuel is placed in the fuel tray the fuel is dispensed and flows into the burner tray. Fuel in the tray is transmitted to the outer surface of the porous element. Flammable vapors from the liquid fuel at the outer surface are then ignited. The arrangement provides a continuous feed of fuel to the surface of the non-flammable structure and allows safe replenishment of the fuel in the burner while the flame is present.
