| A pilot tube assembly comprises a gas inlet tube and a pilot tip with a central aperture. During delivery of gas, one or more apertures of the assembly aspirate ambient air to provide a combustible mixture. A central tapered bore of the assembly receives a gas inlet tube. The tapered bore of the pilot tip is swaged with a gas inlet tube by application of force. The taper angle of central tapered bore ranges from about 1 to 2 degrees, and is preferably 1.5 degrees, with respect to the center line of the pilot tip to enable swaging action at reasonable pressures and to enable a large thermal contact area between the pilot tip and gas inlet tube, thereby equilibrating their temperatures and preventing separation due to thermal expansion. | ||||||

| A relighter apparatus for operating a pilot burner for a fuel pipeline heater. The relighter apparatus has a controller located at a first location, and a pilot burner assembly and ignition coil located at a second location which is remotely located a distance from the first location. The ignition coil is also electrically connected to the controller. The ignition coil receives a low voltage input based on a signal from the controller and provides a high voltage output at the output thereof. Current corresponding to the high voltage output is transferred from the ignitor coil, through a terminal and to an ignitor rod. A conduction of the electrical current between the second end of the ignitor rod and the pilot burner assembly causes an adequate spark to ignite the air/fuel mixture in the pilot burner assembly, creating a pilot flame. | ||||||

| A combined thermocouple and thermopile capable of producing multiple EMF signals. The combined thermocouple and thermopile construction is particularly adapted for use as an electric generator capable of producing multiple EMF signals and able to respond faster to changes to the presence or absence of a pilot or gas burner flame. The conductors of the thermopile are comprised of dissimilar metals joined at each end to form hot and cold thermocouple junctions. The thermopile may provide multiple EMF signals when a third wire lead is affixed to a cold junction between either end of the array. The array of thermocouples is formed in a circle and enclosed in a metal sleeve or jacket. A thermocouple assembly comprised of a standard ferric chrome, nickel chrome or inconel tip; an insulated constantan wire longitudinally centered within and permanently connected to the tip; an insulated copper extension wire permanently affixed to the constantan wire and an insulated copper wire permanently affixed to the outside of the tip; is longitudinally centered within and isolated from the thermopile array contained within a metallic sleeve. The tip of the thermocouple is positioned near but isolated from the thermopile array and metallic sleeve to prevent thermal conductance through the sleeve. | ||||||

The entrance end 28 of the fuel supply conduit 26 is disposed axially upstream of the upstream most surface 40 of the deflector body 38. The exit end 30 of the fuel supply conduit 26 is disposed relative to the deflector body 38 and the air supply conduit 20 at a location FSE downstream of the upstream most surface 40 of the deflector body such that fuel flowing in the fuel supply conduit 26 from its entrance end 28 to its exit end 30 is isolated from contact with air in the air supply conduit 20 until exiting the exit end 30 of the fuel supply conduit 26. The exit end 36 of each branch passage 32 is radially spaced from the exit end 30 of the fuel supply conduit 26. The gas pipe ignitor also includes an ignition element 42, as seen in FIG. 2, for promoting the ignition of the fuel which has exited the branch passages 32. | ||||||

| A pilot burner assembly for a gas burning heater which has a pilot fuel supply pipe and a pilot burner head with an inner chamber defined by a generally continuous sidewall. The pilot burner head has a middle body region with a side port defining a channel passing through the sidewall which has a channel wall. An ignitor rod passes at least partially into the port and terminates at an ignitor tip which is adapted to provide electrical current between the ignitor tip and the sidewall to ignite a pilot flame. A boss is welded on the burner head and surrounds the port. An insulation sleeve is positioned within the boss and has a central aperture adapted to allow passage of the ignitor rod and maintain the ignitor rod in position. A pilot flame sensor is positioned adjacent the pilot burner head and adapted to indicate the ignited pilot flame to a computerized control means. The control means operates a pilot fuel supply valve and the ignitor rod to initiate spark at the ignitor tip and ignite the pilot fuel when the pilot flame is not indicated by the sensor. The control means is also adapted to operate the main valve solenoid to close the main valve when no pilot flame is detected, and optionally maintains the pilot valve open with electrical current of decreased voltage when the sensor indicates a pilot flame. The control means further has an on-demand toggle switch having a first position whereby the control means provides electrical current to open the pilot valve and to spark the ignitor rod when the pilot flame sensor indicates no pilot flame to provide continual pilot burning, and a second position whereby the control means provides electrical current to open the pilot valve and current to the ignitor rod when the burner demand indicator indicates demand for the burner and the sensor indicates no pilot flame to provide on-demand pilot flame. | ||||||

| In a pilot light igniter for a burner, an inner tube for receiving fuel gas is concentrically positioned within an outer tube for receiving air in the annular space between the inner tube and the outer tube. Apertures are formed in the inner tube to impart angular momentum to the fuel gas as it flows from the inner tube into the annular space so that the mixture of air and gas swirls as it flows to the open distal end of the outer tube. A spark disk is provided on the end of the inner tube and a flame rod extends axially from the spark disk. The air and fuel mixture is ignited by a spark produced by high voltage applied between the spark disk and the outer tube. A low voltage source applied between the flame rod and the outer tube causing current pulses provides an indication of the presence of a flame. | ||||||
| 158 | Gas pilot-igniter for burners | US254840 | 1988-10-07 | US4946384A | 1990-08-07 | Paul W. London |
| A gas pilot-igniter is used for igniting combustible gases in a burner, particularly high velocity gas streams. The gas pilot-igniter includes an air inlet manifold for supplying air under pressure to a mixing venturi, a fuel gas manifold for directing fuel into the venturi for primary mixing with air, and a pre-combustion chamber in a main combustion chamber. The pre-combustion chamber is formed by a baffle placed in the path of the flow stream of the fuel/air mixture for creating turbulence and secondary mixing. In addition, the baffle guides the fuel/air mixture to an igniter, such as a spark plug, for igniting the fuel/air mixture to produce a pre-combustion flame. The fuel/air mixture also flows around sides of the baffle and into the main combustion chamber where it is ignited by the pre-combustion flame, producing a constantly regenerated pilot flame which exits a pilot output nozzle to ignite the main burner fuel/air mixture. | ||||||
