This paper reports the computational simulation on combustion behavior of solid particle fired by a Single Annular Orifice (SAO) Burner in a 0.6 x 3.0 m, 300 kW cylindrical furnace, aiming to investigate an underlying mechanism of char reactivity that results in distribution of temperature and oxygen. Attention is given to parametric study of the governing mathematical model for char reaction rate; namely, i) the Mass-Diffusion-Limit Rate Constant (C1) and ii) the Kinetics-Limited Rate Pre-Exponential Factor (C2). Additionally, the effect of boundary condition on temperature distribution in the External Recirculation Zone (ERZ) is also investigated, ranging from 1300, 1400 up to 1500 K. The result is validated against existing experimental work done in the past with bituminous coal particle. It was found that the adiabatic wall is not appropriated and the recommended value for current investigation is 1300 K up to 1.5 m from the burner exit. The enhancement factor of 2.5 for char reaction model yields good agreement of oxygen concentration in the far burner region. Work is still in progress for improvement of predictive quality of the model.
