Pulverized coal combustion is extensively used in utility boilers, industrial boilers, furnaces, kilns, and other energy conversion appliances. The effective utilization of pulverized coal is the main problem in study of combustion processes, particularly in burning low-grade coal. It is well known that the emission of nitrogen oxides (NO_{x}) during coal combustion is a main environmental problem. In this study, three different pulverised coal burner geometries for a pulverised coal fired boiler have been studied by numerical analysis. GLI-Tunçbilek coal was used as fuel. Three-dimensional numerical analysis was carried out using Ansys Fluent code. Realizable K-ε turbulence method, single rate devolatilization method, multiple char combustion method and second-order upwind discretization method were used during calculations. Coal particle diameter and coal mass flow rate were assumed to be 70 μm and 378 kg/h respectively.
