摘要： A stream of hot oxygen is formed by providing a duct and a fuel lance movable axially within the duct, flowing gaseous fuel out of the lance into the duct, mixing it in the duct with gaseous oxidant, flowing the mixture out of the duct into an atmosphere which is hot enough that it ignites the mixture without aid of an ignition source other than said atmosphere, and combusting said mixture in a flame that does not extend into said duct; then moving the lance so its fuel outlet approaches the duct exit orifice so that the base of said flame moves inside said duct to the fuel outlet; and then moving the lance to draw the fuel outlet and the flame attached thereto away from the exit orifice into the duct; and increasing the flow rate of gaseous oxidant in said duct, so that combustion of fuel within the duct heats uncombusted oxygen which emerges as a stream of hot oxidant.

摘要： A method for igniting a fuel/oxidant mixture in an industrial furnace. At least one fuel supply conduit and at least one oxidant supply conduit is provided, each conduit having an opening that opens on a side of the burner head that faces the furnace interior space. Fuel and oxidant are supplied to the burner head, and a light detector for detecting ultraviolet light, or other light wavelengths, is provided for detecting light that indicates the presence of a flame. A laser is positioned to emit a laser beam onto a point on the burner head adjacent the conduit outlets and to heat that point to a temperature exceeding the ignition temperature of the fuel/oxidant mixture. When the burner has ignited, the detector emits a signal to a control circuit that extinguishes the laser beam.

摘要： A method is provided for initiating and sustaining a combustive reaction in a solid fuel. The method includes generating at least one pulsed optical signal and directing the pulsed optical signal to a plurality of ignition points within at least one combustion chamber containing a solid fuel. The pulsed optical signal is generated by an optical source, e.g. a laser pump, and modulated using an intensity profiler. The intensity profiler modulates the pulsed optical signal to initially have a first peak power sufficient to initiate a combustive reaction in a solid fuel. The intensity profiler further modulates the pulsed optical signal to subsequently have a second peak power sufficient to sustain the combustive reaction until sufficient exothermic energy is released by the combustive reaction to make the reaction self-sustaining.

摘要： There are described a method, an apparatus and an ignition pellet for the ignition of combustible gases, for example from a flare or flare tower, where an ignition pellet is launched in a direction toward a region of combustible gas, characterized in that the ignition device is propelled by means of a pressure medium through a guidance tube to the gas cloud region, that the ignition device undergoes a reaction for the purpose of active ignition of the gas in the region, the time for its activation and reaction being predetermined and adapted to the particular flare and application. The reaction of the ignition device is in the form of a shower or cloud of sparks where at least parts of the shower of sparks will strike the cloud of gas. The ignition device is activated somewhere along its path through the tube, possibly at the moment when the ignition device leaves the tube, possibly when the ignition device starts its journey through the tube, or possibly by the fact that the ignition device strikes an object in the vicinity of the flare. The ignition device may be positioned within a trapping device prior to the reaction of the ignition device. The ignition device may be propelled through the guidance tube at a moderate speed, may optionally be stopped during its passage through the tube and may optionally be reversed and returned back into the guidance tube without a reaction taking place.

摘要： A method and assembly for igniting a burner using a pyrophoric liquid. A quantity of pyrophoric liquid is first transported from a container to a slug launching chamber and then transporting into a fuel gas stream for the burner. The slug launching chamber is flushed with a hydrocarbon liquid to remove any of the quantity of pyrophoric liquid from the launching chamber, while the assembly can be purged with an inert gas prior to removing the pyrophoric liquid container and replacing it with a new container.

摘要： Method and apparatus for igniting an air/fuel spray (26) comprised of fuel droplets. The apparatus includes a coherent optical source (12) for introducing at least one pulse of coherent radiation into the air/fuel spray. The pulse generates free electrons and initiates a development of a plasma within the air/fuel spray. The coherent source maintains the pulse of coherent radiation and pumps the developing plasma to higher energies. The pulse is terminated at a time after the plasma has reached a predetermined energy and before ignition of the air/fuel spray. The non-linear ignition system of the invention employs a gas/vapor interface region at a fuel droplet surface and an electric field that extends from and exists outside of a fuel droplet. Free electrons are accelerated to higher energies by the electric field surrounding the fuel droplet. The accelerated electrons initiate a breakdown near adjacent fuel droplets and the liberation of further free electrons. In a short period of time an avalanche process occurs that creates a high density of free electrons and ions which results in the formation of a plasma.

摘要： There is disclosed a structure for rapidly and efficiently igniting charcoal briquettes of the type employed with home barbeque grills.A housing generally comprises a longitudinal cylindrical form fabricated from a plurality of non-combustible rings which are secured to a frame to form an enclosure for accomodating a desired amount of fuel. The frame includes a central support ring located near the top end of the housing and a bar located a given distance from the bottom of the housing. The bar has a projecting central portion.A sheet of combustible material is rolled to form a tubular member and is inserted in and encircled by the top support ring of the frame with the projection on the bottom bar surrounded by the tube at the other end. The combustible tube forms a flue and is surrounded by charcoal which is emplaced within the housing. The tubular flue is then lit.The housing in combination with the flue causes a rapid circulation of heated air. The process is regenerative and the charcoal briquettes which surround the flue are rapidly and efficiently ignited.
