The fingerprinting system includes a main body, an air movement source, an ignitor, and a hydrocarbon fuel source. The main body includes a handle. The air movement source includes a fan. The air movement source is coupled to the main body. The fingerprinting system is configured to burn the hydrocarbon fuel source to produce soot containing carbon. The air movement source is configured to direct the soot containing carbon toward a surface to be analyzed for fingerprints.

Embodiments of the present disclosure describe burner configurations used in an industrial process to convert methane to olefins, aromatics, and nanoparticles/nanomaterials. Both a vitiated coflow burner and piloted turbulent burner with inhomogeneous inlets are disclosed.

Systems, methods, and devices are provided herein for burners. In one aspect, a burner is provided comprising at least one air pipe; at least one fuel pipe; a plurality of groups of mixing units disposed at a downstream end of the burner, wherein each of the plurality of groups of mixing units is arranged coaxially and adjacent to one another, and each group of mixing units comprises at least one fuel channel connected to the at least one fuel pipe and at least one air channel connected to the at least one air pipe, wherein an outlet of the at least one fuel channel and an outlet of the at least one air channel are angled at a certain degree relative to one another such that the fuel flowing out of the outlet of the at least one fuel channel is mixed with the air flowing out of the outlet of the at least one air channel, thereby achieving multiple-stage mixing of the air and fuel.

Embodiments of the present disclosure describe burner (10) configurations used in an industrial process to convert methane to olefins, aromatics, and nanoparticles/nanomaterials. Both a vitiated coflow burner and piloted turbulent burner with inhomogeneous inlets are disclosed.

A pilot and burner apparatus is provided for use in firefighting training. The apparatus includes a main fuel conduit and a main fuel valve. The apparatus includes a pilot tube and a pilot fuel conduit configured to deliver fuel from the main fuel conduit to the pilot tube. The apparatus includes main and pilot fuel valves to respectively control a flow of fuel in the main and pilot fuel conduits. In a pilot phase, the valves direct fuel to the pilot tube. An ignition component is configured to ignite fuel in the pilot tube to generate a pilot flame. In a burn phase, the pilot flame generates a controllable flame out of a main burner pipe by igniting fuel exiting the main fuel conduit. The controllable flame can be delivered to a training structure for training purposes.

A burner system, preferably including input plumbing, a combustion region, and an exhaust section. In some embodiments, the burner system can include, be attached to, be configured to couple with, and/or be otherwise associated with a thermionic energy converter (TEC). A method of burner system operation, preferably including operating the burner system in a combustion mode and optionally including operating a TEC.

A system for use with a fired vessel of production/separators or dehydration equipment that includes a metal box, a main burner, a pilot burner, and a flame arrestor. The main burner and the pilot burner are within the metal box and the first flame arrestor is connected to the metal box.

A radiative recuperator preheats oxidant and/or fuel for combustion at one or more burners of a furnace. The recuperator includes a duct, at least portions of which comprise a material having a thermal conductivity of greater than 1 W/(m.Math.K), preferably greater than 3 W/(m.Math.K), that receives hot flue gas produced by the burner(s). The duct radiatively transfers heat to oxidant or fuel (for preheating) flowing through one or more metallic pipes disposed in between the duct and an insulating wall.

A cement kiln burner device includes a powdered-solid-fuel flow channel having means for swirling a powdered-solid-fuel flow; a first air flow channel placed inside the powdered-solid-fuel flow channel to be adjacent to the powdered-solid-fuel flow channel having means for swirling an air flow; a second air flow channel placed in an outermost side outside the powdered-solid-fuel flow channel having means for straightly forwarding an air flow; and a combustible-solid-waste flow channel placed inside the first air flow channel. The second air flow channel is divided in a circumferential direction into four or more opening portions adapted to form ports for injecting air flows, and is configured to control flow rates of the air flows ejected from the opening portions, independently for each opening portion.

A flame arrester/burner assembly with a multifarious arrester element for preventing deflagrations and extended endurance burning time (FABA-XT). The multifarious element flame arrester includes a pipe body having a first end and a second end, a first arrester element positioned within the pipe body adjacent the top end; a third arrester element adjacent the bottom end; and, a second arrester element positioned in the pipe body between the first arrester element and the second arrester element. The first, second, and/or third arrester elements may be of the same design or disparate designs. The FABA-XT of the present disclosure is an end-of-line burner element for use in VOC-Vapor Destruction Systems.
