This is the fourteenth Technical Progress Report, describing work performed under DOE Contract No. DE-FC22-90PC89663, ``Development of a Coal Quality Expert.`` The contract is a Cooperative Agreement between the US Department of Energy, CQ Inc., and ABB Combustion Engineering, Inc. This report covers the period from July 1 through September 30, 1993. Five companies and five host utilities have teamed with CQ Inc. and ABB/CE to perform the work on this project. The work falls under DOE`s Clean Coal Technology Program category of ``Advanced Coal Cleaning.`` The 51-month project will provide the utility industry with a PC expert system to confidently and inexpensively evaluate the potential for coal cleaning, blending, and switching options to reduce emissions while producing lowest cost electricity. Specifically, this project will: (1) Enhance the existing Coal Quality Information System (CQIS) database and Coal Quality Impact Model (CQIM) to allow confident assessment of the effects of cleaning on specific boiler cost and performance; and (2) develop and validate a methodology, Coal Quality Expert (CQE) which allows accurate and detailed predictions of coal quality impacts on total power plant capital cost, operating cost, and performance based upon inputs from inactive bench-scale tests.
