Definitions

  • the burner has an inner or central conduit and nozzle aligned along the longitudinal axis of the burner and a coaxial concentric outer conduit with a converging frustoconically shaped outer nozzle radially disposed about the outside of said inner conduit and nozzle along their length,
  • An annular cooling chamber encircles the tip of the burner.
  • Burners such as used for the partial oxidation of hydrocarbons consist of two concentrically arranged tubes both of which are tapered towards the nozzle end, as shown in FIGS. 1 and 2 of the accompanying drawing.
  • the cooling chamber may be formed by machining an annular recess in the solid material of the outer nozzle 1, thereby forming flanges 2 and 3 which are spaced a short distance apart.
  • Plane wall 4 of the cooling chamber is located at the outermost extremity of the downstream tip of the burner. It is normal to the longitudinal axis of the burner and faces the reaction zone. Lateral closure of the cooling chamber is effected by means of a ring 5 which is slid over the cooling chamber and welded to the outer edges of the flanges by welds 6.
  • the design of the cooling chamber necessitates the use of a plane front plate 4 which must be very thick if high pressures are used in the reactor. As a result, heat removal is poor; and consequently, the surface of the plate facing the reaction zone reaches a high temperature. High thermal stresses are set up therefore, between the hot external surface and the cooled internal surface.
  • the subject invention pertains to a burner for use in introducing raw materials into the reaction zone of a gas generator where at an autogenous temperature in the range of about 700 to l,900C and a pressure in the range of about I to 250 atmospheres by the partial oxidation of a hydrocarbon fuel with a free-oxygen containing gas optionally in the presence of a temperature moderating gas a gaseous mixture comprising hydrogen and carbon monoxide is produced, said burner comprising a central tubular conduit and central nozzle extending therefrom disposed along the longitudinal axis of said burner through which a first stream is passed said central nozzle terminating in a single unobstructed circular orifice; and outer coaxial concentric conduit and outer converging frusto-conically shaped nozzle extending therefrom radially disposed from said central conduit and central nozzle along their length for simultaneously introducing a second stream into said reaction zone, said outer nozzle terminating in a single unobstructed circular orifice located at the outermost face of the burner; an autogenous
  • the life of the subject burner has been extended to more than days in comparison with an average life of 20 to 30 days for conventional burners by providing small wall thicknesses at the burner throat, shielding from direct radiation from the reaction zone the welds required for constructing the cooling chamber, spacing the inlet and outlet connections to the cooling chamber 180 apart, and using austenitic chromium-nickel steel as the material of construction for the cooling chamber in the region of the burner throat.
  • FIGS. 1 and 2 representing a prior art burner has been previously referred to.
  • FIG. I is a sectional view of the downstream end of the prior art burner assembly.
  • FIG. 2 is a vertical end view of the prior art burner of FIG. 1.
  • FIG. 3 is a sectional view of the downstream end of the burner assembly of the subject invention.
  • FIG. 4 is a vertical end view of the burner of FIG. 3.
  • the present invention pertains to a burner comprising a cylindrical conduit and a concentric coaxial outer conduit radially disposed about the outside of said cylindrical conduit along its length. Near the downstream end of the burner, the outside surface of the central conduit and the inside surface of the outer conduit form a single concentric converging annular discharge passage.
  • the cooling chamber is composed of machined parts and designed in the form of a tubular ring of approximately hemispherical cross section, (2) the welds made in constructing the cooling chamber from parts of the outer tube are so placed that they are not directly exposed to the radiant heat of the flames in the reaction zone and the reactor lining; (3) austenitic chromium-nickel steels are used as materials of construction for the cooling chamber in place of costly high nickel alloy; and (4) the thickness of the wall of the cooling chamber in the region of the outer lip is smaller than in conventional designs.
  • the present invention relates to a burner for the production of synthesis gas by partial oxidation of hydrocarbons with a free-oxygen containing gas optionally in the presence of a temperature moderating gas such as steam and/or carbon dioxide at a temperature in the range of about 700 to l,900C and a pressure in the range of about 1 to 250 atmospheres.
  • the subject burner comprises an inner or central tube 20 disposed along the longitudinal axis of the burner and having a downstream central nozzle 35 provided with an inner unobstructed cylindrically shaped discharge orifice 36 and a converging frustc-conically shaped outside surface 37.
  • a concentric coaxial outer tube 21 having a downstream concentric converging frusto-conically shaped outer nozzle 38 is radially disposed from said inner tube 20 and central nozzle 35 along their length so as to provide a frustoconically shaped single unobstructed converging annular discharge passage 22 at the burner throat.
  • Outer nozzle 38 comprises at least two sections 25 and 26, each being a substantially converging frusto-conically shaped tapered section.
  • Outer nozzle 38 has a convergence angle in the range of about 20 to 50 with the longitudinal axis of the burner.
  • Section 25 is joined to outer tube 21 and to section 26 by welds 27.
  • Welds 27 join said parts on the side facing the outside surfaces of inner tube 28 and central nozzle 35, and are thereby protected from radiant heat from the reaction zone of the gas generator.
  • Austenitic chromium-nickel steels are used as materials of construction for sections 25 and 26.
  • the thickness of the wall of cooling chamber 24 in the region of the outermost lip portion of section 26 is from 1 to mm, and preferably from 2 to 4 mm.
  • the free-oxygen containing gas is introduced into the reaction zone by way of the central conduit and nozzle, while simultaneously the hydrocarbon stream optionally, in admixture with temperature moderating gas is introduced into the reaction zone by way of annular discharge passage 22.
  • the passage of these streams through the burner may be alternated.
  • An annular cooling chamber 24 encircles the downstream tip of said burner.
  • Cooling chamber 24 has an inside wall in common with the end portion of said outer nozzle 38.
  • a tubular ring 39 of approximately hemispherical cross section comprises the outside wall of cooling chamber 24.
  • Tubular ring 39 is welded to the side of converging frusto-conically shaped tapered outside surface 40 of outer nozzle 38 by welding bead 41.
  • Weld 41 is protected from radiant heat from the gas generator by cooling coils 23. Further, coolant passing through cooling chamber 24 conducts heat away from welds 27 and 41.
  • tubular ring 39 is on the side of the burner and fairs into a narrow flat ring section 42. Section 42 is the outermost downstream end of outer nozzle 38 and is normal to the longitudinal axis of the burner.
  • Reference character 43 designates an unobstructed circular discharge orifice at the outermost face of the downstream tip of the burner.
  • Outer discharge orifice 43 is defined by the intersection of an imaginary plane through flat surface 42 and the inside peripheral surface 44 of converging frusto-conically shaped outer nozzle 38.
  • converging outer nozzle 38 terminates at outer orifice 43.
  • Inner discharge orifice 36 is preferably slightly recessed upstream from outer discharge orifree 43. However, in some cases both orifices may terminate in the same plane; and in some unusual circumstances inner orifice 36 may terminate downstream from outer orifice 43.
  • Cooling coils 23 encircle the burner near the region of the downstream tip and provide means for supplying cooling chamber 24 with a coolant.
  • a particularly advantageous additional measure consists in arranging the connections so that supply inlet 28 and withdrawal outlet 29 for the coolant are at diam etrically opposite points. In this way the presence of a large number of welds over a small area of the cooling chamber is avoided and the risk of stresses occurring in the material is thereby diminished.
  • cooling chamber 24 is constructed by welding machined sections to outer tube 21.
  • the hemispherical cross section of the tubular ring section 39 of the cooling chamber makes possible the use of thinner walls.
  • the wall thickness may be in the range of about 1 to 5 mm, and preferably from 2.0 to 4 mm. The decrease in the thickness of the wall facing the reaction zone ensures better heat removal. This means that the material in the region of the burner throat is subjected to less thermal stress and is less susceptible to corrosion by hydrogen sulfide formed in the combustion chamber.
  • the special design of the cooling chamber including the use of at least two appropriately turned parts to form outer nozzle 38 enables the welds joining these parts to be so placed that they are not directly exposed to the radiant heat from the reaction chamber and its brick lining.
  • welds 27 are arranged in such a Way that they are preferentially on the side of the tapered section of the burner throat which faces the inner tube.
  • connections 28 and 29 for the supply and withdrawal of coolant to the cooling chamber are advantageously welded onto opposite sides of the ringshaped cooling chamber of below), it was surprising and unexpectedly found that the subject burner could be made from austenitic chromiummickel steels which have less thermal resistance but which can be worked more easily and are less expensive.
  • the hightemperature strength of VZA alloy steel at 550C. is l2 l5 kg/mm
  • the use of austenitic chromiumnickel steels offers particular advantages with regard to corrosion resistance from hydrogen sulfide.
  • hydrogen sulfide is formed during the combustion of the sulfur-containing feedstocks in the reaction zone and has a corrosive action at the high temperatures prevailing in the region of the burner throat. On the outermost surface of the front face of conventional burners, the temperatures exceed 700C.
  • Suitable feedstocks for operating the burner are gaseous and liquidhydrocarbon, e.g., methane, gasoline and particularly crude oil and heavy fuel oil. These feedstocks are mixed in suitable equipment and, if desired after being preheated to from 250 to 500C., supplied to the outer tube of the burner.
  • the oxygen required for heating and partial oxidation is advantageously preheated and introduced through the inner tube of the burner. Either substantially pure oxygen (95 mole 0 or morel air, or air enriched with oxygen greater than 21 O2) is employed for the combustion of the hydrocarbons.
  • Standard temperature and pressure (STP)/hr of substantially, pure oxygen preheated to 110C and mixed with 440 kg per hr. of steam is introduced into the reaction zone through the inner tube of the burner.
  • STP standard temperature and pressure
  • 2.5% by weight of steam is introduced in admixture with the oxygen.
  • the reaction takes place in the reaction chamber at 1,350C.
  • the burner which is made of V2A steel, is troublefree in operation during more than 100 days, producing 47,000 m per hr. (STP)/hr. of synthesis gas having the following composition (volume dry basis): CO 46.2%, H 47.0%, CO 5.6%, N 0.7%, and CH 0.5%.
  • the gas also contains 3.0 g of H 5 and 100 mg of COS per m (STP).
  • EXAMPLE 2 In the industrial synthesis-gas plant mentioned in Example 1 another experiment is carried out using a different feedstock and throughput but with the same burner. On an hourly basis, 8,200 kg per hr of Landau crude oil is mixed with 5,000 kg per hr. of steam at a pressure of 82 atm., preheated in a heating coil to 320C and introduced through the cooled outer tube into the burner chamber. Cooling of the burner is effected withl7 m per hr. of water at a pressure ofl0 atm. At the same time 7,000 m per hr. of substantially pure oxygen preheated tol 10C and mixed with 300 kg per hr. of steam is introduced through the inner tube; this means that 3.0% by weight of steam is used with reference to oxygen. The reaction takes place in the reaction chamber at 1,280C.
  • a burner for use in introducing raw materials into the reaction zone of a gas generator where at an autogenous temperature in the range of about 700 to l,900C. and a pressure in the range of about 1 to 250 atmospheres by the partial oxidation of a hydrocarbon fuel with a free-oxygen containing gas optionally in the presence of a temperature moderating gas a gaseous mixture comprising hydrogen and carbon monoxide is produced said burner comprising a central tubular conduit and central nozzle extending therefrom disposed along the longitudinal axis of said burner through which a first stream is passed, said central nozzle terminating in a single unobstructed circular orifice; an outer coaxial concentric conduit and outer converging frusto-conically shaped nozzle extending therefrom radially disposed from said central conduit and central nozzle along their length for simultaneously introducing a second stream into said reaction zone, said outer nozzle terminating in a single unobstructed circular orifice located at the outer most face of the burner; an annular cooling chamber containing no internal ba
