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 premix burner which comprises a combustion head comprising, in turn, a perforated covering element provided with a plurality of openings. The premix burner is characterised in that it is provided with a device for generating and delivering a minimum granted thermal power completely arranged inside the combustion head. Moreover, the device comprises a concave element, whose concavity faces the internal wall of the perforated covering element.

Abstract: An improved pilot burner includes an orifice plate defining a central orifice for metering a supply of gas and a gas tube. The gas tube includes a tube wall and defines a supply opening at a first end. The orifice plate is positioned within the gas tube at the supply opening, and the tube wall is crimped around the orifice plate to secure the orifice plate to the gas tube. The pilot burner also includes a burner tube having a first end for receiving a first end of the gas tube. The burner tube further includes a second end defining a flame opening. In another embodiment, a clip is used to secure the gas tube and the burner tube to a bracket.

Abstract: A computer-controlled matrix of pixels that emit bursts of fire in a controlled manner to create moving images and text on a plane in front of the matrix. The unit houses a number of pixels in a grid array, with each pixel associated with a solenoid gas valve. The valves are supplied by a main gas bus and when actuated release gas to an individual pixel, where it flows out and over a constantly burning pilot light and combusts. The valves are connected through a main circuit box to a computer, and are controlled by software that allows the user to script and play complex graphical animations, musical compositions, scrolling text, as well as real-time graphical response to specific user inputs.

Abstract: A flare stack that preferably comprises a burner assembly, an exhaust stack, an housing, and a fuel line. The burner assembly burns a fuel to generate thermal energy and combustion byproducts. The exhaust stack is cooperatively associated with the burner assembly to direct the thermal energy and combustion byproducts away from the burner assembly. The housing at least partially defines a fluid-receiving chamber in thermal communication with the exhaust stack. The fluid-receiving chamber has a heat-transfer fluid disposed therein. The fuel line is in fluid communication with the burner assembly to deliver fuel to the burner assembly. At least a portion of the fuel line is in thermal communication with at least one of the exhaust stack, housing, or heat-transfer fluid to permit fuel in the fuel line to absorb thermal energy before reaching the burner assembly.

Abstract: A combustor with a burner maintains combustion stability. The burner includes an air hole member 31 with a plurality of air holes 34, 35 provided at an upstream side of the combustion gases generated by a combustion chamber 1. A first fueling nozzle 33 jets fuel in a direction crossing a central axis of the burner towards at least two of air holes 35. A plurality of second fueling nozzles 32, one for each of the remaining air holes 34, are provided to jet the fuel in a direction routed along the burner axis towards the corresponding air hole 34. A fuel header 30 distributes the fuel to the first fueling nozzle 33 and each of the second fueling nozzles 32. A fuel header storage unit 70 shrouds the fuel header 30, fueling nozzles 32, 33, and has an air inflow hole 71.

Abstract: An improved hand held starting/charging system tester. According to one aspect of the present invention, the portable handheld tester includes a connector to which various test cables can be removably connected to the tester. Detection circuitry within the tester determines which of several types of test cable is connected to the tester before testing. According to another aspect of the present invention, the portable handheld tester includes an improved user interface that permits a user to review test data from previously performed tests and further permits a user to either skip a previously performed test (thereby retaining the previously collected data for that test) or re-do the test (thereby collecting new data for that test). According to yet another aspect of the present invention, the portable handheld tester that performs a more complete set of tests of the starting/charging system.

Abstract: A liquid fuel combustion device which includes a fuel tank, a combustion section which includes an inner and an outer flame cylinder and an outer cylinder surrounding the flame cylinders, and a wick having one end in the fuel tank for being immersed in the liquid fuel therein and the other end disposed between the flame cylinders so as to draw fuel to the other end. Structure is also provided for guiding air through the combustion section to provide oxygen to support combustion between the flame cylinders of fuel evaporated from the wick such that the heat produced by the combustion serves to evaporate the fuel from the other end of the wick. Detector elements are provided for respectively detecting the temperature of the exhaust gas from the combustion section and the temperature of the air guided to the combustion section by the guide structure.

Abstract: A wick assembly for a liquid fuel combustion apparatus is structured by laminating a main wick and an auxiliary wick, and sandwiching a separator of an oil-impermeable material therebetween. By being so structured, the main wick can be made being hardly deteriorated in terms of its calorific value. A material having a large oil containing ability can be selected for the main wick, and distance between the oil level and top of wick can be made shorter. Fire-spreading time of the wick assembly after a lapse of long service period is still as short as that at the beginning of the service, and generation of an objectional odor and carbon monoxide at the time of ignition can be suppressed constantly.

Abstract: A cup is provided adjacent the generator tube of a kerosene lantern for holding a measured amount of fuel. A wick is located in the cup for burning the fuel at a controlled rate. A foraminous housing extends around and above the wick to control the entrainment of air with the fuel from the wick during burning and to direct the resulting flame against the generator tube thereby preheating fuel in the generator tube to its vaporization temperature until the heat of combustion of fuel at the mantle causes the vaporization of fuel in the generator to be self-sustaining.
