The technical objectives of this project are: to identify the effect of the mode-of-occurrence of toxic elements in coal on the partitioning of these elements between vapor, submicron fume, and fly ash during the combustion of pulverized coal; to identify the mechanisms governing the post-vaporization interaction of toxic elements and major minerals or unburnt char; to determine the effect of combustion environment (i.e., fuel rich or fuel lean) on the partitioning of trace elements between vapor, submicron fume, and fly ash during the combustion of pulverized coal; to model the partitioning of toxic elements between various chemical species in the vapor phase and between the vapor phase and complex aluminosilicate melts; and to develop a frame work for incorporation of the results of the program into the Engineering Model for Ash Formation (EMAF). A description for the work plan for accomplishing these objectives is presented in Section 2 of this report. The work discussed in this report highlights the accomplishments in the first quarter of this two year program. This includes holding the program kick-off meeting, selection of candidate program coals, preliminary combustion experiments at MIT, and development of a quality assurance/quality control document. Specifically, in Section 3 the authors briefly discuss the kickoff meeting and some preliminary discussions concerning a collaboration and coordination with other DOE contractors. Section 4 contains a discussion of the criterion used to select the candidate coals, and a brief description of the background for selecting each candidate coal. Preliminary combustion experiments at MIT are discussed in Section 5. Finally, Section 6 discusses the preliminary framework for the QA/QC protocol document.
