Definitions

  • the present invention relates to a method for incinerating, in particular refuse, in which substances to be incinerated are introduced into a combustion chamber and burned on a fire grate in the combustion chamber, and the flue gases are drawn off from the combustion chamber, these being swirled by adding secondary air and afterburning the Flue gases occur.
  • Such a method and a suitable combustion boiler are known for example from DE-C-30 38 875.
  • the transition from the combustion chamber to the flue gas outlet is constricted by nose-shaped projections of the walls of the combustion chamber which are formed on opposite sides.
  • secondary air is injected, whereby the flue gases are swirled in order to mix the flue gas strands created in the combustion chamber and thereby prevent caking on the oblique wall surfaces of the noses.
  • the exhausting flue gases still contain a high level of pollutants, in particular halogenated hydrocarbons, which is why such incineration plants no longer meet the air quality requirements to be expected in the future.
  • the present invention is based on the object, starting from a method of the type described above, to improve it in such a way that such guidance and mixing of the flue gases is possible that a considerably improved degradation of the pollutants contained in the flue gases, in particular the halogenated hydrocarbons, is effected.
  • this is achieved in that the acceleration and deceleration of the flue gases takes place within a zone which is formed like a venturi tube and is symmetrical to the axis of the flue gas outlet; and that the secondary air below the throttling over the entire cross section of the flue gas flow before the flue gases flow into the afterburning zone are blown in a direction opposite to the direction of flow of the flue gases into the afterburning zone, so that the flue gases are additionally braked in order to keep the flue gases in the Increase the combustion chamber further.
  • a flue gas build-up is thus effected within the combustion chamber, so that the dwell time of the flue gases in the combustion chamber is increased.
  • This smoke gas accumulation takes place in an area of the combustion chamber where the temperature is approximately uniform at 900 . C to 1050 ° C is present. In this way, however, an effective decomposition of the halogenated hydrocarbons in the flue gas is achieved, whereby the intensive swirling of the flue gas caused at the same time as the flue gas accumulation causes the flue gas strands to be completely dissolved before they enter the afterburning zone.
  • the afterburning according to the invention brings about an additional braking of the flue gases before entering the afterburning zone, which supports the braking in the combustion chamber caused by the injection of the secondary air. It is advantageous according to the invention if the fumes last for about 8 seconds.
  • the secondary air is preferably injected into the combustion chamber at a flow rate of approximately 60 to 90 m / s.
  • the present invention relates to a combustion boiler, in particular for waste incineration, consisting of a combustion chamber with a fire grate and with a task arranged above the fire grate, the combustion chamber having a throttle in its upper area opposite the fire grate and pointing in the direction of a flue gas outlet, and wherein in the area of the throttling there is an air injection device for secondary air which has a plurality of nozzle openings for carrying out the above method according to the invention, the injection device for the secondary air in the flow direction of the flue gases being arranged immediately upstream of the throttle-like throttle which is symmetrical to the axis of the flue gas exhaust and the nozzle openings point towards the combustion chamber.
  • the present invention due to the braking achieved in a defined temperature range of the combustion chamber, with combustion temperatures of about 900 ° C to 1050 ° C, such a complete combustion of the flue gases is effected that a comprehensive degradation of the halogenated hydrocarbons, especially the Dioxins, is guaranteed.
  • the flammable components carried in the flue gases are also completely burned out due to the intensive supply of oxygen and the intimate mixing of the combustion chamber zone upstream of the injection zone. This ensures a significant contribution to the improvement of PCDD and PCDF emissions.
  • An inventive combustion boiler 1 in particular a waste incineration boiler, as shown in FIG. 1, consists of a combustion chamber 2, in the bottom of which a combustion grate 3 is arranged.
  • this is a roller grate that slopes downwards at an angle to the horizontal.
  • the roller grate consists of six rollers arranged one behind the other and running parallel to one another.
  • Underneath the combustion grate 3 there are feeds 4 for supplying cold combustion air, so-called primary air, into the combustion zone 5 surrounding the grate 3.
  • the combustion air supplied via the feeds 4 is sucked out of the waste bunker by a downwind fan. This suction is carried out so that the dust load of the sucked air is as low as possible.
  • the air is preferably taken directly from the bunker wall on the boiler house side. Appropriate measures ensure that the intake noise only slightly increases the noise level in the bunker.
  • the primary air intake ducts are provided with sufficiently large and easily accessible cleaning openings at the dust accumulation points.
  • In the combustion chamber 2 opens above the upper end of the combustion grate 3, seen in the direction of transport of the garbage, see arrow X, a waste task 6.
  • the outlet opening 7 of the waste task 6 widens over inclined surfaces 8, 9 into the combustion chamber 2.
  • the combustion chamber 2 above the Combustion grate 3 consists of a lower section 2a, which is formed above the lower end of the grate in the region of an opening 10 forming the boiler outlet and the two lower rollers of the roller grate, so that this section is located approximately in the lower third of the combustion grate 3 and of one Ceiling wall 11, which runs parallel to the grate 3, is limited at the top.
  • the height of the section 2a above the combustion grate 3, i.e. H. above the rollers corresponds approximately to the diameter of the rollers.
  • the zone corresponds approximately to the cooling zone of the combustion slag.
  • the combustion chamber 2 widens upwards and opens into a flue gas outlet 12, the width of the flue gas outlet 12 corresponding approximately to half the length of the grate 3 and, in the exemplary embodiment shown, being approximately 5 m, for example, in adaptation the desired combustion output of the combustion boiler 1 according to the invention.
  • the approximately horizontal connection opening 13 between the combustion chamber 2 and the flue gas outlet 12 is located directly above the mouth of the waste task 6 and forms a flow cross section that is symmetrical to the axis of the flue gas outlet.
  • the combustion chamber 2 has a rear wall 14, which extends vertically upward from the ceiling wall 11 and extends directly into the rear wall 15 of the flue gas outlet 12.
  • the front wall 16 of the flue gas outlet 12 runs parallel to the rear wall 15 and extends upwards from the end of the inclined surface 9, which adjoins the waste application 6.
  • the area of the flue gas outlet 12 directly in the flow direction of the flue gases behind the connection opening 13 has a throttle 17, which is also symmetrical to the flue gas outlet axis and, in the advantageous exemplary embodiment shown, is designed like a venturi tube.
  • This venturi tube-like zone 17 represents an afterburning chamber in which the flue gas mixture first receives an acceleration to approximately 8 to 10 m / s and then a speed reduction to approximately 4 to 5 m / s. This results in relative movements within the flue gas flow, so that the flue gas and temperature strands are mixed intensively. This results in an improved combustion of the flue gas mixture and thus an increased breakdown of the residual pollutants contained therein, in particular the halogenated residual hydrocarbons contained therein (e.g. dioxins).
  • the smooth surface and relatively high design of the combustion chamber 2 with a preferably rectangular or square cross section above the drying and combustion zone of the combustion grate 3 without projections and noses prevents the occurrence of caking.
  • the configuration according to the invention enables a uniform flow of the flue gases and the formation of defined combustion zones, as a result of which the combustion behavior is improved in the sense of a uniform combustion.
  • a nozzle device 18 is provided for further supply air.
  • This supply air supplied via the injection device 18 is referred to below as secondary air.
  • the injection device 18 is designed in such a way that the air jets emerging from it form a quasi-seamless grid, so that no streak of flue gas can penetrate this area without coming into intensive contact with the injected secondary air.
  • this injection device 18 consists of a nozzle bar which extends transversely to the direction of the flue gas flow from the front to the rear of the flue gas outlet 12 and is mounted in the walls.
  • nozzle bar 18 Depending on the size of the cross section of the connection opening 13, two or more spaced, parallel nozzle bars 18 can also be provided.

  • Such a nozzle bar is known per se from DE-PS 30 38 875, but in the present invention it acts in exactly the opposite direction to the direction of action according to DE-PS 30 38 875.
  • the nozzle bar 18 is arranged such that the sides of the box having the nozzle opening 19 20, 21 run obliquely to the longitudinal axis of the flue gas outlet, preferably at an internal angle of 45 °, facing the combustion chamber 2.
  • the emerging air jets form a gapless grille, so that no streak of flue gas can penetrate this area without coming into intensive contact with the injected air.
  • the direction of injection of the secondary air is opposite to the direction of exhaust of the flue gas, so that turbulence and a separation of the flue gases are generated in the area in front of the throttle 17, which increases the dwell time of the flue gases in this area, which has a temperature level of 900 ° C to 1050 ° C has, is additionally increased and a residence time of the flue gases in this area of approximately 8 seconds is achieved. This ensures the degradation of the halogenated hydrocarbons.
  • the secondary air can escape from the nozzle openings 19 at a speed of over 60 to 90 m / s. Furthermore, the air injection means that the combustible components carried in the flue gases burn out completely in the upper combustion zone as a result of the intensive supply of oxygen.
  • tertiary air nozzles 22 can advantageously be arranged in the front wall in the area of the inclined surface 9 shortly before the transition to the venturi-like zone 17 and in the rear wall 14 just above the end of the ceiling wall 11.
  • tertiary air is blown into the flue gas stream, preferably at a speed of more than 60 m / s. This is intended to achieve thorough mixing, the depth of penetration of the air jets and the distribution of the nozzles being dimensioned such that the flue gas stream, in particular in the wall area, is completely detected.
  • These nozzles are advantageous as a supplement to the nozzle bars 18, since air, in particular, is sufficiently penetrated into the areas in the vicinity of the walls in order to effect complete combustion in this area as well.
  • the secondary and tertiary air systems are completely separate from the primary air system.
  • the suction takes place by separate air blowers below the boiler ceiling.
  • all intake ducts and pressure-side air ducts are dimensioned so that the flow speed of 15 m / s is not exceeded. It is also advantageous if the air ducts are adequately stiffened and the connections of the ducts and the suspensions on parts of the building, boiler and furnace scaffolding are designed to be elastic and structure-borne noise-reducing.
  • the total NO x content in the flue gas can be reduced with complete combustion by the invention.
  • an ammonia system 24 is connected to the secondary air system.
  • the nitrogen oxide content is as follows, 5 to 10% NO 2 and 90 to 95% NO.
  • the invention ensures a uniform penetration of the flue gas with ammonia, both in the combustion chamber and in connection with the combustion chamber in the afterburning area of the venturi-like zone.
  • the invention also makes it possible to control or regulate the supply of the secondary air and / or the ammonia supply as a function of the temperature existing in the injection zone of the secondary air, which can be measured by temperature sensors attached to the nozzle bar.
  • the temperature can be increased or decreased by increasing or reducing the secondary air values.
  • this injection device preferably consists of two nozzle bars 18, which extend transversely to the direction of the flue gas flow from the front to the rear of the flue gas outlet 12 and are rotatably mounted in the walls by means of fixed and floating bearings.
