Combustion

     Computational Fluid dynamic (CFD) is a powerful predictive tool used in combustion research. CFD is used for evaluation and optimization of burner and OFA port sizing and location. The numerical modeling provides the detailed boiler performance information that could not be obtained through physical modeling or plant testing. Improper combustion results in either increased level of nitrogen oxide causing air pollution or unburned char particles.

Combustion in Boiler
CFD simulations in utility furnaces have applications such as:

  • Examining the effects of burner tilt (in tangentially fired furnaces), burner swirl, and out-of-service burners on coal misdistribution and ash deposition.
  • Relating the effects of furnace flow patterns to CO and NO emissions and unburned carbon in ash
  • Designing and characterizing the performance of low-NOx burners.
  • Designing high-performance furnace.

  • Combustion in Rotary Kilns
        CFD simulation allow to compare the influence of different burner designs on flame shape on the radiation received by the material bed to be calcinated, to understand the influence of several inlet parameters concerning either the fuel used, or the kiln geometrical dimensions, the position of the burner in the kiln, the various velocities.
