This work describes the results achieved analyzing the complex phenomenology associated with interaction of a particle-laden turbulent flow with the slag-covered wall of an entrained flow gasifier. Two approaches are considered to address coal particle fate: experimental analysis of sample collected in operating gasifiers and a new numerical simulation approach based on a multilevel modeling. Results shed new insights on the effective mechanisms of coal particle conversion highlighting the role of the turbulence on the distribution of particles in gasifiers.
