Definitions

  • the invention relates to a method for regulating the Temperature in thermal waste treatment plants with the Features of the preamble of claim 1 and one Waste treatment plant with the features of the preamble of Claim 3.
  • the waste stream to be eliminated is regarding its Structure extremely heterogeneous.
  • the invention has for its object the generic to design thermal waste disposal so that outside of Start-up and shutdown processes dispense with primary energy sources can be.
  • the invention is the thermal waste treatment for the auxiliary firing required if necessary inexpensive fuel provided which, moreover a contribution to conserving fossil fuel resources accomplishes.
  • Waste materials are added in a reaction chamber 1 with the addition of Combustion air implemented.
  • the waste materials can be one Pyrolysis, charring or burning will.
  • the resulting reaction gas is in one Waste heat boiler 2 cooled and then reused fed.
  • the substitute fuel is delivered in a Processing device 3 for setting the desired Properties such as B. the size distribution of the granules or other mechanical process engineering properties Processing step z. B. by crushing or Subjected to pelleting.
  • the one so prepared Substitute fuel is temporarily stored in a bunker 4.
  • the bunker 4 is with a discharge member 5 like a screw conveyor or cellular wheel sluice, which with an allocator 6 connected is.
  • This allocator 6 can be used as a transmission vessel pneumatic conveying. The function comes to him to, the mass flow or enthalpy flow of Complying with substitute fuel.
  • the allocator 6 is over a Supply line 7 connected to an insertion device 8, through which the substitute fuel is separated from the waste materials is introduced pneumatically into the reaction chamber 1.
  • the amount of the substitute fuel entered is determined by the Fire performance of the reaction chamber 1 regulated. To this end is at the gas outlet of the reaction chamber 1 Temperature sensor 9 arranged. This temperature sensor 9 is connected to the distributor 6 via a control line 10 and provides the information for setting the Mass flow. Another sensor can be used as a thermometer or as a particularly imaging thermography system 11 for Monitoring the reaction conditions in the reaction space 1 be trained. A corresponding regulation based on the Allocator 6 acts, causes the actual value of the mass flow or the enthalpy current of the substitute fuel the previously set target value corresponds. In the procedural scheme the instrumentations which the relevant properties of the to be eliminated Waste stream, which is introduced into the reaction chamber 1 Combustion air flow or the properties of the used Determine substitute fuel flow and also on the Control the allocator 6 act.
  • the entry device 8 for the substitute fuel is not provided with its own ignition device, the Dosage of the substitute fuel via a control first then released when the conditions in the reaction chamber 1 for auto ignition of the substitute fuel.
  • the reaction chamber 1 as Fluidized bed reactor, as a rotary kiln or as a grate be trained.
  • 2 is a waste incineration plant shown, the roller grate formed from grate rollers 12 and has an overlying combustion chamber 13.
  • combustion chamber 13 represents the reaction space of the thermolytic conversion, via a feed hopper 14 and a push conveyor 15.
  • Die Waste forms a bed 16 on the roller grate that passes through the rotation of the grate rollers 12 through the combustion chamber 13 is moved through.
  • Combustion air is through the underwind channels 17 below the Roller grate fed to the combustion chamber 13.
  • Combustion air is the combustion air 13 as secondary air and / or the one adjoining the combustion chamber 13 Afterburning zone 18 blown in.
  • the post-combustion zone 18 is followed by a waste heat boiler, not shown. The too eliminating waste stream reached after complete Implement the dropping 19 and there is from the combustion chamber 13 removed.
  • the entry device 8 can consist of a lance 20, through which the substitute fuel pneumatically into the Combustion chamber 13 is introduced.
  • the lance 20, which in the 2 is only shown schematically, can be in the ceiling 21st of the combustion chamber 13 may be attached. In this Installation position is the energy input from the Substitute fuel on the front part of the on the Roller grate lying bed 16 fed. Except in the ceiling 21 can the entry device in the rear wall 22, or as by the lines 8a indicated in, the side walls of the Combustion chamber 13 may be arranged.
  • the lances 20 can extend their lifespan heat-resistant materials with a Provide double jacket water cooling or with a jacket pipe be equipped using so-called fog air.
  • This fog air can be the one normally used Replace all or part of secondary air.
  • the lance 20 with a mouthpiece be provided, which is in the form of a diffuser is trained.
  • the lance 20 can with the side or rear wall 22 or Cover ceiling 21 of the combustion chamber 13 flush or protrude into the combustion chamber 13.
  • the direction of the Exit velocity vector of the substitute fuel can compared to the normal of the wall or ceiling 21 by one Be inclined. This is useful if possible Installation location is spatially distant from the place where the Additional energy is introduced by the substitute fuel.
  • an angled adjustment of the lance 20 allows one Optimization of the process.
  • the information required to control the arbiter 6 to the temperature or other properties of the Reaction conditions in the combustion chamber 13 are indicated by a Thermography system 11 or a temperature sensor 9 in the Post-combustion zone 18 won.
  • the entry device 8 for the granular 3 can also be used as a muffle 23 be trained.
  • the muffle 23 has a swirl head 24, into which the lance 20 dips.
  • the swirl head 24 is over one Channel 25 designed as a diffuser with a mixing chamber 26 connected, which are all arranged in the same axis.
  • the Mixing chamber 26 is cylindrical and fireproof executed. It expands towards the end of the exit diffuser-like.
  • the swirl head 24 is air to dilute the Volume concentration of the substitute fuel over a connected, with a butterfly valve 27 provided air line 28 are supplied. This allows in particular that the substitute fuel via a Screw conveyor can be fed to the swirl head 24.
  • the air tangentially supplied to the swirl head 24 leaves together with the substitute fuel the swirl head 24 over the diffuser-like channel 25.
