Definitions

  • the invention relates to a burner for a rotary kiln, with an annularly disposed within a combustion liner tube channel for the pneumatic transport and blowing of fine-grained solid fuel through an annular die and a plurality of concentrically arranged around the circumference of the annular gap nozzle distributed jet air nozzles with the burner axis diverging nozzle openings through which Combustion air is divided into many single high-speed primary air jets.
  • Known rotary kiln burners are usually designed as so-called three-channel burners (eg. DE 43 19 363 A1 ), wherein through the central burner channel a pneumatically transportable solid fuel such.
  • the radial inside the coal dust channel lying primary air channel has at its outlet a swirl generator, so that the primary air emerging there receives a rotational component and also swirl air. Swirl air or radial clearance is called.
  • the known swirl generators are usually not adjustable, certainly not during operation of the rotary kiln.
  • the combustion air of the rotary kiln burner also referred to as jet air, which is radially external to the pulverized coal, is determined by means of a plurality in the annular jet air duct arranged individual nozzles in many individual high-speed primary air jets, which generate a negative pressure area in their environment, that is, the many high-speed primary air jets serve as propulsion jets according to the injector, through which the large mass of the rotary kiln surrounding, practically stationary hot secondary air of z. B. is sucked inward towards the core of the burner flame, for example, where intensive mixing of the hot secondary air takes place with the exiting through the annular nozzle coal dust, which is to burn quickly and completely to form a mostly required short hot flame.
  • the cylindrical nozzle body with their nozzle axis with an angle hired nozzle holes are individually rotatable, but not during the rotary kiln operation, so that during the furnace operation not by adjusting the Divergenzwinkels the jet air jet influence on the optimum pulverized coal jet air mixing and Flame shape can be taken.
  • a rotary kiln burner is known, are arranged in the primary air duct around the circumference flexible metallic air hoses with air nozzles whose air flow direction can be adjusted from axial to radial, by rotation of the entire air hose bundle, the flexible air hoses with their Heilausströmdüsen also obliquely to the burner axis to increase the swirl component the radial clearance can be adjusted.
  • this known spin adjustment of a rotary kiln burner is relatively expensive, in the known burner only a parallel outflow of fuel and primary air is possible, even if the primary air is provided with a swirl component.
  • the invention has for its object to provide a rotary kiln burner, especially for fine-grained solid fuels with jet air nozzles that are easy and yet effectively adjustable during the rotary kiln operation in order to change the Divergenzwinkels the jet air jets in response to different types of fuel and / or resulting flame shapes.
  • the jet air nozzles are attached to the burner axis diverging nozzle openings respectively at the end of jet air ducts, which are arranged axially parallel to the burner axis, within a ring surrounding the solid fuel channel outside of the combustion liner limited cooling air ring channel.
  • the jet air pipes are rotatably mounted in the cooling air ring channel, wherein at the cold end of the burner lance outside of the combustion liner, the means for rotational adjustment of the jet air pipes is arranged.
  • the bearings of the individual jet air pipes are held in two spaced apart flange rings of the combustion liner.
  • the annular space between the spaced flange rings can be formed within the provided with a jet air supply nozzle fuel return pipe as inflow, from which the supplied jet air flows through through holes of the jet air pipes into this and then flows out of the jet air nozzles.
  • flexible hoses for supplying jet air into the jet air pipes can also be connected to the jet air pipes which can be rotated individually or jointly about their longitudinal axes at their outer ends remote from the jet air nozzles.
  • FIG. 1 shows the complete burner lance with nozzle 10 for the introduction of coal dust, 11 for the introduction of jet air, 12 for the introduction of swirl air, 13 for the possible introduction of alternative fuels and 14 for the introduction of cooling air for internal cooling of the fuel tube 19, which is externally armored by an applied refractory mass 15 is.
  • the introduced fuels burn after emerging from the burner mouth to form a flame at the right end of the burner lance in the rotary kiln.
  • the rotary kiln burner according to the invention is a three-channel burner with a ring-shaped channel for the pneumatic transport of fine-grained solid fuel such.
  • the coal dust channel is concentrically surrounded both by a radially inwardly and radially outwardly located combustion air duct, these combustion air streams forming the primary air for the burner.
  • the concentrically arranged within the coal dust channel primary air channel is at its mouth with a swirl generator 17th z. B. swirl slots, so that this radially inner primary air duct is also called swirl air duct.
  • still pilot burner and the outlets 18 may be arranged for the combustion of the optionally introduced alternative fuels 13. 19, the combustion liner is called, which is protected in the front lance area by the applied refractory material 15.
  • the radially outer primary air namely the introduced jet air 11 emerges at high speed in the form of jet streams of individual distributed around the circumference of the burner mouth jet air nozzles 20, z. B. 16 pieces, of which in the detail drawing FIG. 3 the Jetluftdüse 20 can be seen with its divergent to the burner axis nozzle bore.
  • the high-speed jet air jets which are capable of as much as possible of the rotary kiln burner in the rotary kiln surrounding hot secondary air of z. B. 1000 ° C in the core of the burner flame for the purpose of rapid and complete intake of pulverized coal, should meet the fuel cone at an optimal location in order to achieve large flame turbulence.
  • the Jet Kunststoffdüsen 20 with their diverging to the burner axis nozzle openings according to the invention in each case at the end of z. B. 16 jet air pipes 21, which are arranged distributed axially parallel to the burner axis, and within a surrounding the coal dust duct outside of the fuel tube 19 limited cooling air ring channel 22, flows into the cooling air through the nozzle 14 of the support tube 19 and at the burner mouth in the area between the adjacent jet air nozzles 20 flows out, where then the heated in the burner lance cooling air forms a portion of the primary air.
  • the jet air pipes 21, which are distributed around the circumference, are mounted rotatably about their jet air tube axes. So can after FIG. 4 the rotatable bearing points of the jet air pipes 21 may be held in two spaced-apart flange rings 23, 24 of the combustion support tube 19.
  • the device for rotational adjustment of the jet air pipes is arranged outside of the fuel tube 19.
  • the jet air pipes 21 can carry toothed crevices 25 at their outer ends closed in the exemplary embodiment, which can be in rotational engagement with a ring or band or link chain, not shown, provided with internal toothing.
  • FIG. 4 is the annular space between the spaced flange rings 23 and 24 formed within the provided with the JetLiteeriementsstutzen 11 Brennertragrohres 19 as Anströmkasten 26, from which the supplied jet air flows through through holes 27 of the jet air pipes 21 therethrough and then flows out of the Jetluftdüsen 20.
  • the inflow air box 26 is sealed by ring seals in the flange rings 23, 24 with advantage to the outside.
  • a certain leakage rate of jet air can be readily accepted according to the invention, however, because the leakage current of jet air would then form part of the cooling air already used for the burner within the cooling air ring channel 22.
  • FIG. 5 it can be seen that in the cooling-air annulus between the omitted in this figure, the fuel supply pipe 19 and the pulverized coal pipe with the annular gap nozzle 16, in which annular space distributed around the circumference rotatably mounted jet air pipes 21 are arranged with their jet air nozzles 20, a flow-through for the cooling air spacers 28 is arranged, which keeps the jet air pipes 21 and the concentric tubes 16, 19 at a distance. Furthermore, it is off FIG. 5 also clearly seen that in the cooling air ring space between the combustion liner 19 and the coal dust pipe 16 at least some of the gaps between adjacent jet air pipes 21 can be exploited to order therein a tube 18 for supplying an alternative fuel and / or possibly devices for monitoring the burner flame ,
