Babcock & Wilcox has been leading a team in the development of an advanced coal-fired low emission boiler system (LEBS). The project objective is to design a new pulverized coal (PC) powered generating system equipped with improved combustion and heat transfer subsystems and advanced environmental control technologies capable of achieving emissions of NO{sub x}, SO{sub x}, and particulates far below current New Source Performance Standards (NSPS). The objectives of the program are to achieve continuous NO{sub x} emissions below 0.2 lb NO{sub x}/MBtu with a specified design coal, through combustion techniques only, with a further target of 0.1 lb NO{sub x}/MBtu using supplementary advanced flue gas cleanup technologies if necessary. The SO{sub 2} limit for the project has been set at 0.1 lb SO{sub 2}/MBtu, with a particulate emission limit of 0.01 lb particulate/MBtu. The net plant efficiency is specified to be at least 42% (HHV), while overall the cost of electricity must not increase relative to a conventional plant meeting cur-rent NSPS. The B&W LEBS plant uses conventional state-of-the-art equipment along with developing new technologies to meet the program goals. To meet this goal, B&W has coupled advanced environmental control technologies capable of achieving emission of NO{sub x}, SO{sub x}, and particulate far below current NSPS with an advanced boiler equipped with improved combustion and heat transfer subsystems. Phase I of the LEBS program began with a thorough review and assessment of potential advanced technologies and techniques. Through engineering analysis, pilot-scale testing, and numerical modeling in Phases I and II, a near full-scale 100 MBtu/hr advanced NO{sub x} emissions control system was designed, fabricated, and tested. Further experimental testing and numerical modeling has continued to refine the LEBS concept.
