摘要： A method to recover sulfur from hydrogen sulfide in an acid gas stream comprising the steps of reacting the hydrogen sulfide and oxygen in the combustion furnace, transferring heat from the furnace effluent to produce a boiler effluent, reducing the temperature of the boiler effluent in the sulfur condenser, separating the water vapor from the non-condensed gases stream, reacting the sulfur dioxide and the hydrogen gas to produce hydrogen sulfide in the first hydrogenation reactor, reacting the hydrogen sulfide and oxygen in the reactor furnace to produce a reactor effluent, transferring heat from the reactor effluent to produce a cooled effluent, reducing the temperature of the cooled effluent in the sulfur cooler to produce a gases stream, separating the water vapor from the gases stream, reacting the sulfur dioxide and the hydrogen gas to produce hydrogen sulfide in the second hydrogenation reactor to produce a treated tail gas stream.

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： A burner 100 comprising a burner body 110 having a burner chamber with a backing plate 122 and having a burner element received in the burner chamber, the burner element having a plurality of gas nozzles 117 for supplying gas into the burner, the gas nozzles 117 each ending in a tip through which the gas exits and gas nozzle 117, and each gas nozzle being rotatable such that the direction of gas exiting the gas nozzle can be adjusted. The burner has means for rotating the gas nozzles 117 provided on the backing plate and by releasable means for retaining each gas nozzle 117 in a plurality of rotational configurations provided outside the burner chamber. The gas nozzles 117 further comprise first and second parts which are detachable from each other, the first part comprising the tip and the second part being upstream of the first part with respect to the flow of gas into the gas nozzles in use. The burner allows for tuning of gas flow from outside the burner while it is in use.

摘要： The invention relates to a burner, particularly Low-NOX-burner, for generating a flame by combustion of a fuel, comprising: a tile (15, 15a, 15b) surrounding an opening (2, 2a, 2b) of the tile (15, 15a, 15b) extending along a burner axis (12), the tile (15, 15a, 15b) further comprising a front side (20) and a rear side (21) facing away from the front side (20), wherein the rear side (21) comprises an air inlet (10, 10a, 10b) connected to said opening for feeding air (A, A′, A″) into said opening (2, 2a, 2b), and wherein said front side (20) comprises a discharge outlet (9, 9a, 9b) connected to said opening (2, 2a, 2b) for discharging a flame (30) generated by the burner (1) into a surrounding area (S), and wherein the tile (15, 15a, 15b) further comprises an inside (22) facing said opening (2, 2a, 2b) as well as an outside (23) facing away from said opening (2, 2a, 2b). According to the invention the burner (1) further comprises at least one oxygen lance (5) extending along the burner axis (12) in a first recess (17) of said tile (15, 15a, 15b), the at least one oxygen lance (5) having an ejection nozzle (6) at an end region of the at least one oxygen lance (5) for ejecting oxygen (O), particularly such that the oxygen (O) is at first ejected into a colder flue gas region (31) surrounding the relatively hotter flame (30) generated by the burner (1). Further, the invention relates to a method for generating a flame (30).

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%.
