Abstract:
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.
Abstract:
A split control unit in a distributed flow unit includes a flow inlet configured to receive a fuel flow, a first manifold having flow lines to supply fuel to one or more primary nozzles, and a second manifold having flow lines to supply fuel to one or more secondary nozzles. In an embodiment, the second manifold is in fluid communication with the flow inlet. A metering valve has a first port in fluid communication with the flow inlet and with the second manifold. The metering valve is configured to supply a metered fuel flow to the first manifold. A flow passage is in fluid communication with, and runs between, a flow line of the first manifold and a flow line of the second manifold to allow for a continuous cooling flow in the second manifold when all of the one or more secondary nozzles are closed.

Abstract:
The invention relates to an atomizer (10) for a burner for burning ignitably and atomizingly flowable fuels in the heated state, with a first atomizing nozzle (29) and a burner operation flow pipe section (17a), via which the fuel can be supplied to the first atomizing nozzle (29) for burner operation. In order to enable compact construction at high functional density and more reliable operation a switching device (15) is proposed according to the invention, by means of which the direction of flow of the fuel can be switched over for preheating operation such that the fuel can be diverted via the burner operation flow pipe section (17a) for the purpose of circulating the fuel from the first atomizing nozzle (29).
Abstract:
A pressurisable paraffin burning system (40) comprises a manually re-pressurisable and transportable fuel supply reservoir (42) and a number of liquid fuel burner operable pieces of equipment (46) connected via fuel supply tubing (48) to the reservoir (42) once the system (40) is operatively installed. The reservoir provides for its direct connection to a number of pieces of equipment (46). The system (40) allows for controlling the fuel supply to the pieces of equipment (46) enabling the simultaneous use of a number of them. One of the pieces of equipment (46) is in the form of a geyser (56) comprising a water flow a mantle (12) within which a flue (14) is formed extending above a burner (16). The heat exchange configuration of the geyser (54) incorporates a number of airflow direction mounted plates (20) being heat conduction-fashion situated in a direct flame exposure location across the flue inlet while extending from the immediate vicinity of the inlet to the mantle (12), and a heated gas flow path layout in the form of a helically extending formation (22).
Abstract:
The invention pertains to liquid fuel cooking apparatuses and systems. A liquid fuel cooking apparatus as described is suitable for consumers in resource-constrained environments, and is an effective alternative to traditional solid fuel stoves. The systems as described provide safe, reliable, convenient, and relatively inexpensive means for providing liquid fuel to the cooking apparatus, with minimal human involvement and substantial flexibility afforded to the consumer. The apparatus and systems are environmentally friendly as reducing dependency on solid fuels while minimizing release of liquid fuel vapours and minimizing the risk of spillage.
