The technical objectives of this project are to: Define the partitioning of inorganic constituents 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; and to characterize the resultant spectrum of products in detail; elucidate and quantify the fundamental processes (involving basic principles of physics, chemistry, thermodynamics) 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 nature and distribution of products.
