Blending Powder River Basin coals to meet clean air compliance requirements

Many utilities are considering blending their higher sulfur bituminous coals with lower sulfur Powder River Basin (PRB) coals in order to meet clean air compliance requirements. However, the impacts of these coal blends on the performance of equipment and stack emissions are largely uncertain. Utilities need a validated, systematic methodology to: (1) estimate the modifications that may be required to burn these blends in a cost effective, safe and reliable manner, and (2) systematically and meaningfully test burn PRB to derive necessary performance and planning data. PSI Energy has entered into a Tailored Collaboration Agreement with Electric Power Research Institute (EPRI) in order to address these issues through a PRB coal blend test burn program at PSI`s Gibson Station. This is a first of a kind demonstration of PRB:bituminous coal blends on a supercritical unit of the type in service at Gibson. The objective of the program is to evaluate the feasibility of burning the PRB subbituminous coal with midwestern bituminous coals. The project is intended to develop: (1) a methodology for maximizing the utilized PRB blend fraction; (2) a methodology for evaluating the associated physical improvements and operational enhancements required for the plant; and, (3) an assessment of the incremental unit performance impacts. The test burn PRB blend ratio is to be staged from a minimal level to 100 percent in steps of approximately 10 percentage points. The cumulative physical test burn is expected to require twelve months or longer.
