| Outline of Final Research Achievements |
Ignition process of pulverized coal particle which affects combustion performance and emission characteristics was investigated by an advanced laser diagnostics. Results revealed the detailed behavior of the soot particle formed in the pulverized coal flame which was generated by the polymerization of the tar content in the volatile matter. In order to capture the behavior by a numerical simulation, the essential elementary reactions were investigated and extracted from the detailed chemical mechanism and they implemented into the LES code. The numerical procedure was validated by the comparison with the experiment.
