Definitions

  • the invention relates to a method and a device for burning waste materials in a combustion system for fossil fuels with at least one burner.
  • waste is now being obtained to a greater extent through the targeted separation of high-calorific waste.
  • the invention proposes that the waste material is introduced into the center of the flame cone of the burner in a predetermined quantitative ratio to the fossil fuel and is burned there.
  • both comminuted solid and liquid or gaseous waste materials can be used alone or together.
  • the flue gases generated in the combustion of the waste materials in the flame core of the burner penetrate the hot outer flame screen of the fossil fuel due to the procedure according to the invention and are heated to temperatures at which furans and dioxins formed are split again into harmless compounds.
  • the resulting flue gas flows are thoroughly mixed, as a result of which aggressive constituents in the flue gas of internal waste incineration are greatly diluted and their effect, for example on the boiler walls, is severely restricted.
  • Coal, oil or gas can be used as fossil fuels.
  • the solid waste material is expediently conveyed pneumatically, predominantly with air.
  • the use of partially ionized or inerted gases can be advantageous for certain applications.
  • the carrier medium In order to avoid outgassing, melting and premature burning in the processing and conveying system, the carrier medium should be fed in as cold as possible.
  • characteristic data such as calorific value, flue gas composition, ash composition etc. can be entered into a computer and evaluated in the context of a continuous comparison of actual and actual values.
  • Each burner can be controlled individually so that multiple burners are distributed evenly and the amount of waste is limited.
  • Solid waste material is passed from a bunker 1 via a feeder belt 2 into a comminution device 3.
  • a blower 4 feeds the carrier medium in front of the shredding device 3.
  • waste material / air mixture is conveyed via a line system 5 to a waste material burner 6, which in this example is arranged concentrically in a burner 8.
  • Liquid or gaseous waste material can also be incinerated via a line 9.
  • a line 7 leads the solid fossil fuel with carrier medium and / or liquid or gaseous fuel to the burner 8.
  • a computer 11 a, b evaluates the process data such.
  • B Analyzes (fuel, waste material, total exhaust gas, ash) and thermal outputs (total, fuel, waste material) and controls the amount of fuel via a controller 12 and the amount of waste material via a controller 13 so that perfect combustion of the waste material is guaranteed at all times in the flame core of the fuel.

Abstract

Procédé et dispositif d'incinération de déchets dans un système de combustion à combustibles fossiles ayant au moins un brûleur. Les déchets et les combustibles fossiles sont introduits et brûlés dans un rapport mutuel prédéterminé au centre du cône de flammes du brûleur. Par ce procédé, les gaz de fumée qui se dégagent des déchets brûlés au centre du cône de flammes sont chauffés, en traversant la couche extérieure du cône de flammes, jusqu'à des températures qui assurent la destruction de dioxine et de furanes toxiques par exemple.
