| 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. | ||||||

| 88 | Ignition system for coal gasifier | US97593 | 1979-11-26 | US4372754A | 1983-02-08 | Paul Gernhardt; Wilhelm Danguillier; Karl Peter; Wolfgang Grams; Siegfried Pohl; Peter Schnitzler |
| An ignition burner and a pilot burner form part of an ignition system for a fluidized stream of finely-divided coal particles in a pressurized gasifier housing having a slag overflow pipe coupled to a discharge vessel. A fuel supply pipe delivers fuel for combustion by the ignition burner and the pilot burner. A sparkplug or hot wire is used to ignite the fuel delivered to the ignition burner. The flame produced by the ignition burner is widened by a baffle so that ignition by the pilot burner occurs to produce a flame which is monitored through a thermocouple. The parts forming the ignition system are carried by a pair of levers with pivots on the inner wall of a slag overflow pipe for movement between an operative position wherein the ignition burner is situated near the slag-receiving opening of the overflow pipe and an inoperative position wherein the ignition burner is protected from contact by slag and radiation heating. The ignition burner moves within substantially only one plane extending through the centerline of said slag overflow pipe. | ||||||
| 89 | Universal pilot assembly | US897209 | 1978-04-17 | US4192642A | 1980-03-11 | Roman F. Lempa |
| A pilot assembly for a furnace burner includes a housing having a first port capable of mating with a flame detector which can monitor the pilot or main flame of the furnace burner. The housing further includes an air-fuel mixture inlet port coaxially disposed with respect to a second port, which serves the purpose of mating with a spark ignition means. The axes of the fuel mixture inlet port and second port are substantially perpendicular to the axis of the first port. The second port is adapted such that any portion of the spark ignition means extending through the second port and into the housing will not interfere with the monitoring performed by the flame detector means. The housing further includes a third port which can accommodate means for visually sighting the pilot flame. The third port can also serve the purpose of providing manual ignition of the pilot burner. | ||||||
| 90 | Retrofit igniter | US865406 | 1977-12-29 | US4177034A | 1979-12-04 | Richard E. Jones |
| There is disclosed a bracket and assembly for retrofit conversion of continuous pilot burners to intermittent, on-demand pilot burners. This conversion requires the mounting of a gas ignition electrode in the assembly. The mounting bracket for accomplishing this purpose is a flat metal stamping having a web with distal apertures bearing upstanding peripheral flanges about each aperture, and two pairs of bendable tabs. The bracket is installed with one aperture received about the conventional flame sensor assembly of the pilot burner, and the bendable tabs are bent about the supporting structure to secure the bracket and to support the additional electrode required by this conversion at a predetermined spacing relative to the pilot burner where the electrode tip can be readily bent to the proper air gap for spark ignition. | ||||||

| A gas burner for a water heater provides a unitary bracket removably connected to a gas supplying tube and supporting both a pilot burner and a main burner. The unitary support bracket includes a U-shaped portion surrounding an air-gas mixing area communicating with a centrally located gas inlet opening of a gas distributing head providing a plurality of spaced gas outlet ports. A base portion of the U-shaped bracket portion is spaced from the gas distributing head and includes a tube receiving opening and a pair of flanges functioning with a pair of corresponding tabs on the tube to provide a releasable bayonet type connection. An extension of the unitary bracket removably mounts the pilot burner assembly so that the flame axis is spaced adjacent to the gas outlet ports of the gas distributing head. | ||||||
