Application of the MILD combustion

  • Generate strong internal recirculation
  • f flue gas
  • Flame becomes homogeneously

distributed: flameless

  • Peak temperatures disappear

SLIDE 5

Application of the MILD combustion

Benefits of the technology:

  • elimination of external flue gas recirculation
  • fuel flexibility
  • increased radiation boiler
  • better burn out of fuel
  • lower NO emission
  • lower O2 excess ratio
  • More compact boilers

SLIDE 7

DNS implementation of reactive particles

Focus on particle clustering

Effects related to a turbulent fluid can be accounted for by a modified Sherwood number It is shown how the effect of the turbulence can be incorporated into RANS code

No turbulence model exist for the heterogeneous combustion
