A fire display assembly has a burner tray with a porous non-combustible material located in the burner tray positioned adjacent, on or in a non-combustible structure. A source of a combustible liquid positioned a distance from the burner tray is provided with conduits for flowing liquid fuel between the sources and trays. The conduits can include an adjustable valve to control the amount of fluid flowing there-through. The valves can be preprogrammed to provide a preset flow over time or controlled from a remote location by a flow controller. Ignited fuel from the porous non-combustible material provides the appearance of a burning surface on the non-combustible structure. The arrangement provides a continuous but variable feed of fuel to the porous non-combustible material and allows the fuel feed rate to be varied to provide a variable flame height or to vary the location of the flame in a controlled manner.

Feed and burner control system

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.

Automatic fueling of liquid fuel burners

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.

A forced air heater is described having a plurality of combustion zones and an interceding cooling zone with active cooling devices. Catalytic oxidation may be implemented in the combustion zone whereby efficiency is increased by cooling the combustion products and outflow to more efficient temperatures. The catalytic bed of the combustion zone may be placed downstream of the cooling and primary combustion zone to remove noxious combustion by-products and an afterburner may also be included.
