Title: Demonstration of sorbent injection technology on a tangentially coal-fired utility boiler (Yorktown Limb Demonstration). Final report, June 1987-October 1993

Technical Report ·
OSTI ID:7084694

The report summarizes activities conducted and results achieved in a program to demonstrate Limestone Injection Multistage Burner (LIMB) technology on a tangentially fired coal-burning utility boiler, Virginia Power's 180-MWe Yorktown Unit No. 2. This successfully demonstrated technology combines furnace injection of a calcium-based sorbent for moderate reductions of sulfur dioxide (SO2) with a low-nitrogen-oxide (NOx) firing system for NOx emissions reduction. Testing was conducted on an eastern bituminous coal with a typical sulfur content of 2.3%. Results of both extensive parametric testing and continuous long-term operation of the LIMB system are presented. Results of performance testing of the Low-NOx Concentric Firing System (LNCFS) Level II firing system are also presented. The effects of LIMB operation on boiler, electrostatic precipitator (ESP), and ash handling system performance are also discussed.
