Staubentwicklung während der LKW-Entladung

PreventSecDust – Reduction of dust emissions in the furnace

Initial situation:

  • Due to the wide range of material transports, the preparation of the fluff is one of the largest dust sources in the blast furnace.
  • Important knowledge about secondary emissions is missing.
  • The legal requirements regarding the emissions of dust (especially fine dust) are becoming ever more severe.

Working topics:

  • Examination of existing and development of new methods for dust suppression in laboratory and operational investigations
  • Development and testing of spraying equipment
  • Selection of suitable additives for dust binding
  • Investigation of the effects of blasting on the blast furnace process
  • CFD and DEM simulations to optimize transfer stations

Results:

  • Findings on the mechanisms of secondary emission
  • Improved design of transfer devices
  • Devices for continuous dust monitoring and control of the spraying devices
  • Guidelines for the selection and application of liquid dust binders
