Definitions

  • the invention initially relates to a method for detecting essentially one after the other in the conveying direction of the grate Combustion zones of the grate of outgoing radiation and regulation of the combustion process depending on the radiation detected by changing the transport speed and the supplied to the individual combustion rust zones Primary air.
  • the bed temperature and thus the location of particularly hot combustion points can cannot be detected safely since the flames can be displaced by gas flow over the bed do not show the burns safely.
  • the flame radiation itself represents a phenomenon with faster change over time, which is poorly suited to regulating the air supply and / or transport speed is. For the rest, a regulation of the primary air is sufficient with the transport speed remaining the same Doesn't always rust.
  • EP 352 620 is a method for controlling the Combustion of a fuel in which the infrared radiation corresponding to the material bed temperature detected and the primary air is regulated depending on this. A regulation of the transport speed the fuel in the individual zones is not provided.
  • This object is achieved in that the essentially of individual combustion rust zones of the Rusting outgoing infrared radiation corresponding to the material bed temperature in its area distribution captured simultaneously by means of a thermography or infrared camera and depending on the comparison of the captured area temperature distribution with a predetermined temperature distribution, the primary air supplied and Transport speed of the fuel is regulated in individual zones.
  • the Radiation from the bed itself is detected.
  • the zone-wise regulation of the primary air distribution and the Fuel transport is an improvement of the combustion process on the grate (burnout), a minimization of pollutant emissions and a reduction in the excess air, which according to the prevailing Opinion must also lead to a reduction in the formation of dioxins in the incineration of waste.
  • the zones can be divided not only in the conveying direction, but also across the conveying direction.
  • the grates in which the method according to the invention can be used include in particular the single-lane or multi-lane feed grates, where fixed and movable in each grate track Alternate grate bars.
  • the zone division is achieved here by different primary air supply.
  • these include the single or multi-lane step feed grates, in which the grate gradations Overturning and breaking up of the fuel layer and each rust element cause a rust zone determined in which the primary air can be adapted to the respective burn progress.
  • Such a zoning without gradation is also realized with the so-called burnout grates.
  • the invention leaves but also with moving grates, roller grates, return grids, counter-rotating grids and Use shaking grates.
  • this provides that the detector device for at least one thermography or infrared camera for simultaneous Detection of the infrared radiation corresponding to the material bed temperature in the conveying direction of the grate successive rust zones in their area distribution and the evaluation device the detected compares surface temperature distribution with a predetermined temperature distribution and that the Individual grate zones separately adjustable actuators for the supply of primary air and for the Transport speed of the fuel in the material bed through the individual grate zones are assigned.
  • two infrared cameras are provided, each of which has a side wall of the combustion chamber are assigned and cover the same bed surface. This is redundancy and therefore given increased security of the scheme.
  • FIG. 1 shows a furnace 1 with a step feed grate 2, as shown in the brochure "Combustion technology - moving grate” (P 8303-05-13 / 1.DG) from “L. & C. Steinmüller GmbH, Gummersbach, DE “is described.
  • the feed grate 2 has five combustion zones A, B, C, D and E, with zones B and C and D respectively and E are separated from one another by a stage 3 or 4.
  • FIG. 1 is shown schematically that the movable grate bars of the individual zones A-E are each assigned to a grate slide 5.
  • the grate slides A5 - E5 can be moved back and forth via schematically illustrated hydraulic drives A6 - E6.
  • the combustible material in particular garbage, is fed via a funnel 7 and a hydraulically operated one Dispenser 8 relinquished to grate 2, specifically to dispensing zone 8 '.
  • the allocation zone 8 'and the combustion zones A-E with movable grate bars are each underwind zones 9 or A9 - E9 assigned, to which 10 primary combustion air via control flaps via a line 9 'and A12-E12 can be supplied.
  • the smoke gases rising from the combustion grate 2 can still Secondary air is supplied via a line 12 and control flaps 12 ′ and 12 ′′ via a plurality of nozzles 13.
  • infrared and thermography cameras 15a and 15b arranged so that they cover essentially the entire rectangular area of zones B, C and D. cover in a measuring manner. This can be done with an illustration, not shown, but common in the field. and focusing optics can be achieved.
  • the evaluation circuit 16 On the output side is the evaluation circuit 16 with drives A6 - E6 for the feed and the flaps A12 - E12 connected for primary air supply. It is also possible that the evaluation circuit also the Flap 9 'for the primary air zone 9, the flap 10' for the total amount of primary air, the drive of the distributor 8 and the flaps 12 'and 12 "for the secondary air.
  • FIG. 2 shows a course of combustion along and across the feed direction VS of the grate, which does not lead to optimal combustion
  • the temperature range with the highest assumed here Combustion temperature is too far ahead.
  • H. essentially in the area of zone B, and in the area of Zone D is an area that is lower than the hot area, but should already be here a lower temperature can be reached. The combustion is therefore elongated.
  • thermography cameras 15 record the two-dimensional radiation distribution in the area of the zones B - D and the evaluation circuit compares the resulting isotherms according to FIG. 2 with the predetermined target isotherms, as shown in FIG. 3 are shown.
