Full-scale demonstration of Low-NO{sub x} Cell{trademark} Burner retrofit: Long-term testing
The Low-NO{sub x} Cell{trademark} Burner (LNCB) concept was developed by Babcock & Wilcox (B&W) to effectively reduce the NO{sub x} emissions from pulverized-coal-fired boilers equipped with cell burners. These boilers were built mostly in the mid to late 1960s. Small (6-million Btu/hr) and intermediate (100-million Btu/hr) prototype versions of the concept were developed jointly by B&W and the Electric Power Research Institute (EPRI) during the mid-to-late 1980s. The design of B&W LNCBs allows direct replacements of the originally installed cell burners without pressure-part modifications. During this US Department of Energy (DOE) Clean Coal III program, Dayton Power and Light Company (DP&L) served as the host utility using its J.M. Stuart Station Unit {number_sign}4 (JMSS 4) for the first full-scale LNCB demonstration. This unit has a rated output capacity of 605 MW{sub e}. After the LNCB retrofit and burner optimization contract phases in late 1991, JMSS 4 underwent a long- term (nine months) test period from July 1992 to March 1993. The objective of this test was to determine the overall performance of this boiler after the LNCB retrofit. The long-term test involved determinations of the boiler emission performance and evaluations of waterwall corrosion potential, as well as a study of the overall operability of the LNCB system. Specific tasks performed during this long-term test include: (1) laboratory corrosion study; (2) field corrosion panel study; (3) in-furnace gas species probing; and (4) boiler emissions performance study. This report summarizes the long- term test results.
