A twist of an old technique, flue gas recirculating, helps prevent slagging in the upper furnace and convective pass, according to pilot testing recently completed by APTECH CST and the South Research Institute. The technology, along with a companion technology for furnace sorbent and urea injection for SO{sub 2} and NOx control, could help owner/operators of smaller, older coal-fired plants meet emissions limits at a reasonable cost. The article reviews the details and results of initial pilot-scale testing. Results met all the company's expectations when testing Powder River Basin and Galatia coals. A full-scale project is planned for operation in 2009. 7 figs.
