Definitions

  • the invention relates to a method and a device for feeding industrial furnaces, in particular power plant boilers and rotary kilns, with waste material, in particular with secondary fuel, as well as a fuel produced therewith.
  • substitution rate of the secondary fuel is up to 25% for lignite-fired power plants, while in cement and lime production it even reaches up to 50% of the original primary or standard fuel.
  • an intermediate storage and the transport of the pretreated waste material leads to an influence on its physical properties.
  • moisture absorbed by the waste material can lead to problems in feeding the product into the actual boiler room due to caking in the delivery units. This applies in particular to the use of screw conveyors.
  • a transport by means of augers it comes to Verhakelept the secondary fuel with each other, so that not only the risk of constipation, but in particular form larger units secondary fuel, which after injection via a lance or similar. do not completely burn into a combustion chamber.
  • the surface of the comminuted material is reduced by storage and under the additional influence of various environmental and material parameters, in particular by moisture, which is absorbed from the ambient air, and by the weight of the secondary fuel, which adversely affects not only the transport but also the burning behavior becomes.
