Definitions

  • the invention relates to a method for burning plastic waste.
  • plastic waste which is generated in private households, for example, has either been landfilled as a mixture with the residual waste or incinerated in domestic waste incineration plants.
  • the combustion rooms of the household waste incineration plants are mainly designed as grate furnaces, which are geared towards the calorific value of household waste with regard to their thermal design. Pure plastics cannot be used there alone due to the much higher calorific value and the low melting point (risk of sticking). Accordingly, the plastic fraction that was sorted out of the household waste would have to be homogeneously mixed with the residual waste for thermal recycling in a household waste incineration plant.
  • the method which solves the problem is that the plastic wastes ground to a certain grain size are guided by means of a blowing device accompanied by at least one further separate energy carrier stream and a separate combustion air stream into a combustion chamber of a dust burner, where they are mixed and ignited.
  • lignite and hard coal are normally used to generate energy.
  • the coal is dried with preheated combustion air (maximum temperature 400 ° C), then ground to a grain size smaller than 100 ⁇ m and then blown into the combustion chamber by a burner.
  • the plastic K When the plastic waste is added by a burner 1, the plastic K, ground to a grain size of 1-2 mm, with a non-preheated partial stream of the combustion air in a inner tube becomes concentric around a gaseous fuel, e.g. natural gas G or a cooling air stream in a second tube the inner tube and the preheated combustion air L loaded with or without coal are added to a combustion chamber 2 in a third outer tube which is guided concentrically around the second tube.
  • the fuel and gas streams are guided in such a way that thorough mixing, good flame stability and complete burnout are ensured.
  • the plastic K can be added to the combustion chamber 2 via a separate lance 3, which can be cooled or uncooled, in such a way that the trajectory of the plastic particles remains in the area of high temperatures sufficiently long for complete combustion.
  • Plastic and homopolymers of ethylene, propylene, styrene and polyamide as well as any mixtures of these substances can be used as plastic waste even in the presence of PVC and PET and in compositions that correspond to the plastic fraction in household waste if the maximum grain size is less than 2 mm is.
  • the plastic waste can be introduced into the combustion chamber 2 both via the burner 1, but separately from the coal and air flow, and separately via an additional lance 3.
  • All coal (hard coal and lignite) and conventional fuel gases e.g. natural gas, town gas, synthesis gas etc.
  • the best burnout and emission results were achieved in pilot plant tests with a thermal load share of the plastic of 50 to 80% with hard coal support firing and addition of the plastic via a separate lance.
