Transformations of inorganic coal constituents in combustion systems. Quarterly report No. 21, October 1--December 31, 1991

摘要

The technical objectives of this project are: To: (1) 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 (2) characterize the resultant spectrum of products in detail. To elucidate and quantify the fundamental processes (involving basic principles of physics, chemistry, thermodynamics) by which transformations of the inorganic constituents occur. To develop, based on the information required in a. and b. above, a tractable ''process'' model capable of predicting the significant features of the transformation process, most importantly, the nature and distribution of products.
