CFD Analysis of Blast Furnace Blowpipe

Computational Fluid Dynamics Performed to Study Various Blowpipe Designs

Computational Fluid Dynamics (CFD) Analysis was Performed to Investigate the Cause of a Blast Furnace Blowpipe Breakout and Study Various New Designs.

The investigation included quantifying the failure mode, and evaluating other designs and/or alternative materials of construction. Analysis included:

  • The blowpipe, lance and tuyere
  • Materials of construction, system design, operating data & alarm logs examination of the furnace
  • Failed blowpipe & lance, and exemplar blowpipes and lances
  • Three-dimensional finite element thermal transients

Computational Fluid Dynamics (CFD) was also used to model the hot blast flow in the blowpipe with the coal/nitrogen injection stream. Two cases were analyzed: normal operating flow, and upset conditions with the lance broken off at the inner refractory edge.
