OSTI ID:270717

The use of Powder River Basin (PRB) coals as a blend stock in boilers designed for high-sulfur bituminous coals represents one alternative for meeting the SO{sub 2} emissions requirements of the 1990 Clean Air Act Amendments. This report documents the results of a test burn on a large, supercritical unit to evaluate the impact of PRB coal blends on plant performance and emissions. The test burn was designed to incorporate new operational enhancements as they became apparent while maximizing the PRB coal blend fraction under safe, reliable operating conditions. The report also provides guidelines for planning and conducting a PRB coal test burn. Finally, the report describes enhancements to EPRI`s Coal Quality Impact Model (CQIM{trademark}) in the areas of mill drying, furnace heat transfer, sootblower modeling, precipitator modeling, and component capital costing capability. The enhanced CQIM provides a tool to be used before, during, and after the test burn planning phase to screen candidate coals and various operating scenarios.
