ABSTRACT: Compliance with a fuel sulfur regulatory limit was achieved at B.L. England Station through on-site blending of Powder River Basin (PRB) and Eastern Bituminous coals. A PGNA elemental cross-belt on-line analyzer was installed to control the blending of these two coals and to demonstrate the continuous compliance with regulatory limit on the fuel firing in B.L. England Station Unit 1.
This paper describes the testing, calibration and certification efforts required to optimize the cross-belt analyzer performance and demonstrate compliance with day-to-day coal sulfur content limits. The approach used for reporting the compliance to the New Jersey Department of Environmental Protection is also discussed. The paper includes a comparison of the on-line analyzer test data with coal sampling lab data for sulfur, ash, heat content and moisture. Understanding each of these properties of the blended fuel is significant to the successful operation of this cyclone-fired unit.
