Objectives of this project are to: define the partitioning of inorganic constitutents associated with raw coal particles among products (including vapors, aerosols, and residual char/ash particles) formed under conditions representative of pulverized coal flames as a function of the specific (intrinsic and extrinsic) characteristics of the raw coal and the environment in which the transformations occur; elucidate and quantify the fundamental processes by which transformations of the inorganic constituents occur; and develop, based on the information required above, a tractable process'' model capable of predicting the significant features of the transformation process, most importantly, the distribution and nature of products. This report describes work in the following areas: behavior and effects of coal mineral matter in a laboratory pulverized coal combustor, and idealized combustion determination of ash particle formation and surface stickiness.
