Demonstration of Selective Catalytic Reduction Technology to Control Nitrogen Oxide Emissions from High-Sulfur, Coal-Fired Boilers: A DOE Assessment

摘要

This document serves as the DOE post-project assessment of a project in Round 2 of the Clean Coal Technology (CCT) Program. The Selective Catalytic Reduction (SCR) Demonstration Project was conducted by Southern Company Services (Southern) beginning in June 1990. The objectives of this project were to evaluate: Performance of a wide variety of SCR catalyst compositions, geometries, and manufacturing methods at typical U.S. high-sulfur coal-fired utility operating conditions; Catalyst resistance to poisoning by trace metal species present in U.S. coals but not present, or present at much lower concentrations, in fuels from other countries; and Effects on the balance-of-plant equipment from sulfur compounds formed by reactions between sulfur dioxide (SO2), sulfur trioxide (SO3), and NH3 (e.g., plugging and corrosion of downstream equipment).
