Definitions

  • the present invention relates to a method for optimizing the combustion of exhaust gases of a combustion plant according to the preamble of claim 1.
  • a method for optimizing the combustion of exhaust gases of a combustion plant is described for example in the EP-A-1508745 described.
  • Incinerators for burning solid fuels such as municipal waste, refuse derived fuels, biomass and other materials are well known to those skilled in the art.
  • Such plants include a combustion chamber in which the solid is burned with supply of primary air, which is referred to as primary combustion.
  • the solid from the inlet into the combustion chamber to the outlet through various sub-processes, which can be roughly subdivided into drying, ignition, combustion and ash burning. In each of these sub-processes, exhaust gases of different composition are generated.
  • the primary air While in the drying phase, the primary air only absorbs moisture from the solid to be burned, can be found in the ignition phase pyrolytic decomposition products.
  • the oxygen supplied in the ignition phase is often completely converted, so that the exhaust gas flow generated in this phase has very little or no oxygen.
  • exhaust gases are formed with typical compositions of CO, CO 2 , O 2 , H 2 O and N 2 , while finally over the ash ash practically unused air is present.
  • these different exhaust gas streams pass into a secondary combustion chamber arranged downstream in the direction of flow, where they are burnt out with the supply of secondary air, which is referred to as secondary combustion.
  • a method comprising a combustion of the solid and an afterburning of the incompletely combusted exhaust gas constituents is known, for example, from US Pat WO 2007/090510
  • the aim of this invention is to reduce the primary nitrogen compounds NH 3 and HCN in order to minimize the formation of nitrogen oxides (NO x ) in the post-combustion chamber.
  • EP-A-1077077 relates to a similar process as that of WO 2007/090510 , wherein the denitrification of the flue gases, the SNCR method is used in which no catalyst is used, but a reducing agent is injected into the flue gases.
  • Such SNCR processes operate at temperatures of 850 to 1000 ° C and require sophisticated control.
  • the reduction of nitrogen oxides is also in WO 99/58902 addressed.
  • the gases emerging from the combustion chamber are homogenized with the addition of an oxygen-free or oxygen-poor medium in a mixing stage, after which the homogenized exhaust gas flow passes through a steady zone in which the nitrogen oxides already formed are to be reduced.
  • the amount of accumulating pyrolysis gas is so large that the locally available secondary air quantity is insufficient for complete burnout. This causes unburned gases to escape from the post-combustion chamber, resulting in, for example, CO peaks in the chimney.
  • the peripheral wall surrounding the combustion chamber or the afterburning chamber can be damaged on the one hand by the prevailing high temperatures.
  • caking or coking may occur in this area, which must be removed in time-consuming maintenance work.
  • EP-A-1081434 The problem of reducing the amount of unburned substances and in particular CO, try about in EP-A-1081434 .
  • EP-A-1382906 and US-B-5313895 approached procedures. So is about according to US-B-5313895 a mixed fluid is introduced, the gases leaving the combustion chamber in a Eddy current offset.
  • a special nozzle arrangement is described, by means of which a rotating flow in the flow channel is produced in a plane of injection of the flame in the region of the flame ceiling.
  • US-B-5313895 described method the problem of present in the combustion chamber temperature imbalance only unsatisfactory way.
  • the temperature in the inlet-side region should be reduced by means of injection of water droplets or water vapor.
  • this is disadvantageous in terms of the energy recovery balance.
  • the aim of the present invention is thus to provide a method for optimizing the burnout of exhaust gases of a combustion plant, which on the one hand ensures a high degree of operational reliability and which, on the other hand, allows a high energy recovery from the combustion to be obtained.
  • the method according to the invention comprises the steps of introducing the solid to be combusted via an inlet into a combustion chamber defining a primary combustion chamber, combusting the solid in the primary combustion chamber in the form of a combustion bed conveyed via a combustion grate by supplying primary air and the combusted solid via a combustion chamber in the conveying direction the inlet opposite outlet is discharged from the primary combustion chamber.
  • the primary combustion gases liberated upon combustion of the solid become downstream in the flow direction, i. usually arranged above the combustion chamber, a secondary combustion chamber defining afterburner chamber burned under supply of secondary air.
  • the exhaust gases containing the primary combustion gases are homogenized in a mixing zone. This is done by means of a fluid introduced via a nozzle.
  • nozzle is to be understood as an indefinite article; Thus, the term includes both a single and multiple nozzles.
  • Homogenization is understood in this context to mean that the exhaust gases or the individual exhaust gas streams of different composition are mixed in such a way that the most homogeneous possible gas mixture is obtained.
  • the mixing zone now at least approximately immediately adjoins the combustion bed in the flow direction of the exhaust gases. As a rule, it is thus arranged in other words at least approximately directly above the combustion bed. This allows very hot exhaust gas streams, such as may occur in the ignition or combustion zone, practically immediately above the combustion bed with the cooler exhaust gas streams from the drying and ash combustion zone to mix and thus compensate for temperature peaks early or lower.
  • the method allows the energy recovery balance to be unaffected, as would be the case with cooling by means of a cooling medium.
  • the homogenization of the exhaust gas streams generated in the individual combustion zones results in a gas mixture which is optimally preconditioned for afterburning in the secondary combustion chamber.
  • the present invention thus allows to ensure an optimal combustion of the exhaust gases even at low (secondary) excess air; the emission of pollutants, such as CO or unburned hydrocarbons, can thus be kept very low even with small amounts of supplied secondary air.
  • the fluid is introduced via one or more nozzles.
  • the exit velocity of the fluid from the nozzle is about 40 to about 120 m / s, wherein the nozzle is aligned in the sense of the present invention at an angle of -10 ° to + 10 ° relative to the inclination of the combustion grate.
  • nozzles In addition to the nozzles defined above, there may be other nozzles that are not oriented at the angle defined above relative to the inclination of the combustion grate.
  • Inclination of the combustion grate in this context is understood to mean the total inclination of the grate (and not the orientation of possibly existing individual grate steps).
  • the inventive alignment of the nozzle ensures that even with the inventive arrangement of the mixing zone immediately above the fuel bed excessive swirling of solids is avoided by the rust.
  • the inventive injection rate of the fluid also contributes from about 40 to about 120 m / s.
  • the found combination of nozzle arrangement according to the invention and injection rate thus makes it possible in total to connect the mixing zone in the direction of flow of the exhaust gases at least approximately directly to the combustion bed, without resulting in excessive unwanted swirling of the solids from the combustion grid.
  • the mixing zone is appropriately spaced from the combustion grate. Furthermore, the mixing zone may extend at most to a distance of 2 meters measured from the fuel bed. When considered in the flow direction of the exhaust gases, the mixing zone thus ends after a maximum of 2 meters and thus still at a sufficient distance before the secondary air injection. In the invention At least approximately immediately adjacent to the combustion bed subsequent mixing zone, said upper limit is sufficient to obtain the desired homogenization of the exhaust gases.
  • the exit velocity of the fluid from the nozzle is about 90 m / s.
  • the exit velocity refers to the velocity that the fluid has on exit from the nozzle opening.
  • the nozzles used as standard usually have a circular nozzle cross-section of 60 mm to 200 mm. It is conceivable that the nozzle cross-section continuously tapers in the direction of the nozzle orifice so that the diameter of the outlet opening of the nozzle is 60 mm to 90 mm.
  • the respective nozzle is preferably oriented at an angle of -10 ° to + 5 °, more preferably -5 ° to + 5 °, relative to the inclination of the combustion grate.
  • the respective nozzle may be oriented at an angle of -10 ° to 0 ° relative to the inclination of the combustion grate.
  • the fluid comprises a flue gas returned from a downstream zone of the secondary combustion chamber.
  • the recirculation preferably takes place from one zone between the steam generator and the fireplace.
  • the amount of introduced flue gas is about 5 to 35% of the amount of primary air supplied, preferably about 20%.
  • any other conceivable fluid can be used, in particular air, an inert gas, such as nitrogen, water vapor or mixtures thereof.
  • the injection of the fluid takes place via a nozzle or nozzle row arranged in this region.
  • a very pronounced temperature imbalance and thus damage or contamination of the peripheral wall surrounding the combustion chamber can be effectively prevented.
  • the respective nozzle when a recirculated flue gas is used as the fluid, preferably has an outer tube and an inner tube extending in the axial direction of the outer tube and enclosed by the inner tube, wherein the inner tube is intended for guiding the flue gas and the outer tube for guiding air ,
  • the inner diameter of the inner tube is about 70 mm, while the inner diameter of the outer tube, i. the outer diameter of the present between inner tube and outer tube annular gap, about 110 mm.
  • the air flow in this embodiment serves as a shield which protects the nozzle from the accumulation of contaminants entrained in the flue gas. Especially in the inlet side area Temperatures such deposits could easily lead to caking, which can lead to failure of the nozzle in extreme cases; This is effectively prevented according to the described embodiment. It has proven to be advantageous if at least 1 nozzle per meter of the combustion chamber width is provided. Preferably, the introduction of the fluid via at least two nozzles, more preferably at least six nozzles. This ensures as complete as possible homogenization with a relatively small amount of injected fluid.

  • the nozzle is arranged in a range of at most 3 meters, preferably 0.5 meters to 3 meters, most preferably 0.5 to 2 meters above the combustion grate. In general, the nozzle is arranged in the peripheral wall of the combustion chamber, preferably in the region of the inlet or the outlet.

  • the combustion chamber 8 comprises a peripheral wall 10, which encloses an upwardly tapering, primary combustion chamber 12.
  • the solid 2 is conveyed in the form of a fuel bed 14 via a (advancing) combustion grate 16 through which primary air flows and thereby burned.
  • a drying zone In the conveying direction F, there are successively a drying zone, an ignition zone, a combustion zone and an ash combustion zone, before the burnt solid is discharged via an outlet 18 arranged opposite the inlet 6 and subsequently fed to a slag conveyor via a purifier.
