Abstract

We studied both experimentally and numerically the pulverized-coal combustion process and NO x emissions in a 300 MWe wall-fired boiler burning bituminous coal. In simulations of an enhanced ignition-dual register (EI-DR) burner arrangement, results gave values of 6.39% and 861.43 mg/m3 at 6% O2 for combustible material content in the fly ash and NO x concentration at the furnace outlet, respectively. Meanwhile, simulations with a centrally fuel rich (CFR) swirl burner arrangement gave similar results of 3.63% and 695.36 mg/m3 at 6% O2. Comparing the two, the NO x concentration of the latter had decreased by 19.28%.
