The present work is based on the software ANSYS FLUENT Workbench 15.0. This approach aims to provide an improved estimation of O2 and CO2 compositions from combustion of pulverized coal when the coal was injected pneumatically. This paper presents state of art in the field of pulverized coal combustion using computational fluid dynamic (CFD) approach. The mathematical models used for the combustion of pulverized coal includes realizable K-ɛ model for turbulent flow, species transport model and discrete phase model. For the purpose of simulating the combustion process, 2D mesh was adapted. The composition of O2 and CO2 and the particle trajectory is good agreement with literature.
