摘要： Aspects of the present disclosure include branching fluid passages in an apparatus that reduce turbulent flow and generate evenly distributed fluid pressure as the fluids branch off into the different passages. In some embodiments, the branching passages may be subdivided into two sets: the branching passages for the liquid fuel and the branching passages for the liquid oxidizer. In some embodiments, the two sets of passages are carefully designed in an elegant yet extremely intricate manner that is optimized for proper fluid flow and maximal burn efficiency. The ends of all of the passages meet at the injector interface, which dispense the liquids into the combustion chamber for ignition. Generally, these designs are achieved through additive manufacturing, and would be extremely difficult, if not impossible, to be manufactured using traditional techniques.

摘要： Fluid-cooled impingement burners have an external conduit and a first internal conduit substantially concentric therewith forming a first annulus for passing a cooling fluid. A second internal conduit forms a second annulus between the first and second internal conduits. A burner tip body defined by an inner wall, an outer wall, and a half-toroid crown, the inner wall connected to the first internal conduit, the outer wall connected to the external conduit, the inner wall defining a central flow passage for a combustible mixture. A third internal conduit generally concentric with the external conduit and positioned between the external and the first internal conduits, a first end of the third internal conduit extending into but not connecting with the half-toroid crown. A first end of the second internal conduit recessed is below the half-toroid crown, and the position of the first ends of the second and third internal conduits delay combustion of fuel with the oxidant.

摘要： An object of the present invention is to provide a combustion burner that is capable of efficiently performing heating of a raw material powder by improving the dispersibility of the raw material powder that is ejected from a raw material powder-ejecting port using a simple configuration, and a combustion burner in which raw material powder introduction pipes that introduce the raw material powder inside a raw material powder supply pathway are provided so that axes that extend from central axes of the raw material powder introduction pipes do not intersect a central axis of the burner main body, and so that angles θ that are formed by central axes of the raw material powder introduction pipes and an outer surface of a second circular member are larger than 0° and smaller than 90°.

摘要： A burner apparatus for a fired-heater system and a method of burner operation wherein the burner fuel is ejected outside of the burner wall from a surrounding fuel discharge ring, or from a lateral elongate ejection bar in the case of a flat flame burner, to a combustion zone projecting from the forward end of burner wall. The burner apparatus and method reduce NOx production by a combination of enhanced internal flue gas recirculation and staged fuel operation.

摘要： A high efficiency natural draft gas burner that uses a plate attached to the burner tube to block secondary air from being introduced into a firetube or confined space vessel, ensuring that only inspired air nearly homogenously mixed with fuel is ignited at the burner tip. The venturi may be sized and shaped to ensure proper mixing of the inspired air and fuel, thus reducing emissions. This proper mixing combined with the lack of secondary air may reduce the fuel consumption and CO2 emissions of the burner by as much as 75%.

摘要： A soot glass deposit body is manufactured by placing a starting rod and a burner 22 for producing glass particulates in a reaction container, introducing a source material gas to the burner 22 through a supplying pipe 26, producing glass particulates by a pyrolytic oxidation reaction of the source material gas in a flame formed by the burner 22, and depositing the produced glass particulates on the starting rod. At the time, the source material gas to be supplied to the burner 22 is a siloxane, the burner 22 is heated so that temperature of the burner 22 falls within the range of from −30° C. to +30° C. relative to the boiling point of the siloxane, and also temperature of the supplying pipe is controlled within the range of from the boiling point of the siloxane to the boiling point plus 30° C.
