EFFECT OF AGGLOMERATION ON PULVERIZED-COAL COMBUSTION

The effect of coal particle agglomeration during pulverized coal combu stion is studied using a plug-flow model of a practical coal combustor . The model incorporates turbulent agglomeration, in addition to the c ombustion equations, to explore certain combustor and coal parameters that may be used for optimizing a chosen output parameter (e.g., burno ut time). This routine has been used to develop relations describing t he effects of turbulent agglomeration on pulverized coal combustion as an aid in combustor design or retrofitting. The results of this work indicate that, in agreement with general observations, agglomeration w ill have little impact on pulverized coal combustion in typical combus tors.
