Definitions

  • the invention relates to an industrial furnace with a tubular burner, according to the preamble of claim 1.
  • a particularly preferred field of application of such an industrial furnace are heat treatment plants for mineral goods, such as furnaces for heat treatment or burning of cement clinker, lime, ores and the like, with rotary kilns, calcination or Calcinier raiseden etc, as industrial ovens or industrial furnace plants particularly come into question.
  • the combustion process can be influenced by the design and operation of the burner to the process engineering tasks in such industrial furnaces or kilns, for example, in adaptation to the respective raw material properties, the desired quality characteristics of the produced Products to meet different fuel types, etc.
  • the prescribed emission values have to be complied with, for example with regard to carbon dioxide and nitrogen oxide of such industrial furnaces, with the associated burner - and thus also the corresponding furnace - to be operated in an energy-efficient and economical manner.
  • it is endeavored with the help of the burner in the furnace combustion chamber to form an optimal flame by a favorable mixing of the supplied combustion air or the supplied combustion gas is brought about with the supplied fuel.
  • the earlier patent application EP-A-0 974 552 relates to a burner for partial oxidation of hydrogen sulphide to form sulfur vapor.
  • the burner has a plurality of radially spaced apart and coaxially arranged in one another tube walls which define a plurality of separate and approximately annular in cross-section feed channels for combustion gas and fuel with hydrogen sulphide.
  • the outermost annular feed channel is for hydrogen sulphide containing fuel.
  • the mouth region of the burner is arranged in an opening of the combustion chamber, wherein a further annular channel for supplying combustion air is formed by the mouth region of the burner and the opening of the combustion chamber.
  • the invention is therefore an object of the invention to improve an industrial furnace with a tubular burner according to the preamble of claim 1 so that the interference of fuel in the entire combustion gas or in the entire combustion air and thus the whole combustion process (ignition, burnout of fuels , NO x formation, flame shape and length) can be optimally influenced.
  • the outermost annular supply passage is now substantially configured as a fuel supply passage, and the combustion gas supply passage provided with the individual nozzles is disposed radially inside of this fuel supply passage, as viewed in cross section of the inner burner nozzle.
  • the degree of mixing and mixing of primary and secondary air with fuel is controlled depending on the respective fuels, the loading of the secondary air with dust and chemicals, the furnace geometry by a corresponding orientation of the radially inner individual nozzles.
  • the degree of interference significantly affects the overall combustion process (ie, ignition, burnout of fuels, NO x formation, flame shape and length, etc.).
  • the heat treatment or firing process can be optimally controlled in terms of achieving a good clinker quality and high availability of the associated rotary kiln.
  • the burner designed according to the invention can be used not only in a rotary kiln but also in other industrial furnaces or industrial furnaces where a comparable heat treatment or firing process is to be carried out, as for example in calcination furnaces Calcining, in furnaces for burning lime, for the heat treatment of ores and the like is more the case.
  • the individual nozzles can not only parallel with respect to their outflow direction, but also with a certain Angle to the outflow direction of the outside surrounding fuel supply channel are aligned. It is also conceivable that the orientation angle of the individual nozzles is adjustable. With an oblique orientation of the individual nozzles with respect to the outflow direction of the surrounding fuel supply channel, it is possible to divert the primary air (or the primary combustion gas) flowing in via the individual nozzles into the combustion chamber more or less divergently outwards. In a skewed arrangement of the individual nozzles with respect to the surrounding fuel supply channel, a corresponding swirl can also be generated, so that the mixing effect of primary air and fuel with the secondary air and thus influencing the entire combustion process can still be increased accordingly.
  • This alignment of the individual nozzles can thus be made firmly according to the one embodiment variant according to optimal findings as a basic setting, or the individual nozzles can be adjusted again and again according to the other embodiment depending on the given ratio (be it during operation, be it during a standstill) ,
  • the at least one outer fuel supply channel is indeed intended essentially for the supply of the corresponding fuels (liquid, gaseous or fine-grained or powdery), there, however, quite a certain proportion of combustion air (im Mixture with the fuels) can be supplied.
  • combustion air im Mixture with the fuels
  • the combustion gas supplied via the individual nozzles or the primary air introduced there can also be used If necessary, a certain proportion of fuel are mixed.
  • the inventively embodied tubular burner 1 will be described below with reference to a particularly typical application or application example, namely when used on or in a rotary kiln 2 for the production of cement clinker.
  • a rotary kiln 2 for the production of cement clinker.
  • this rotary kiln 2 only the burner-side or outlet-side furnace end 2a is shown roughly and schematically in FIG. 1, ie this rotary kiln 2 can be designed in any suitable manner.
  • This outlet-side furnace end 2a projects into a conventional furnace outlet head 3, through which the furnace end 2a is connected to the inlet 4a of any suitable cooler 4, which is therefore only briefly indicated in FIG.
  • the inventively embodied tubular burner 1 projects - as is known - with its inner end portion or mouthpiece 1a frontally from the rear and approximately axially into the rotary kiln end 2a into, in the combustion chamber. 7
  • the burner 1 is - as indicated schematically in Figure 1 - in the region of his located outside the rotary kiln 2 outer end portion 1b via corresponding supply lines with fuel (dash-dotted arrows 8) and combustion gas, in particular primary air (dashed arrows 9) and possibly even more Ignition fuels and ignition air supplied in a fundamentally known manner.
  • the burner 1 and its mouthpiece 1a contains a plurality of radially spaced apart and coaxially arranged pipe walls, namely an outer tube wall 10, a coaxial and within this outer tube wall 10 lying first inner tube wall 11 and at least one further coaxial within this first inner tube wall 11 lying second or central pipe wall 12.
  • These tube walls 10, 11, 12 delimit a plurality of separate, approximately in cross section feed channels, namely an outer annular feed channel 13, a coaxially within this outer feed channel 13 lying inner annular feed channel 14 and at least one further inner feed channel 15, in This case as in cross-section approximately circular feed channel 15 within the central tube wall 12, for example, not illustrated here in detail, since known per se pilot burner or the like may be formed.
  • inner feed channel 14 In the facing in the combustion chamber 7 front end 14c of substantially for the combustion gas supply, so in the present case for the primary air supply (arrows 9) formed inner feed channel 14 is a number of individual nozzles 16 approximately - as shown in Figure 3 - arranged distributed annularly, wherein it - as later mentioned again - are fixed or adjustable in an annular end wall 17 is supported, which is fixedly mounted on or in the front end 14c of the primary air feed channel 14.
  • the individual nozzles 16 can in principle - as shown in FIGS. 2 and 3 in solid lines - be aligned in their outflow direction parallel to the burner longitudinal axis 1d in order to ensure the above-described improved mixing effect of the fuel in the combustion air, in particular in the secondary air.
