Development of LIDS{sup {trademark}} as a part of the Babcock & Wilcox low emission boiler system
- Babcock & Wilcox-Research and Development Division, Alliance, OH (United States)
Babcock & Wilcox (B&W) is currently developing an emissions control system capable of dramatically reducing SO{sub x} and particulate emissions while addressing the concerns of solid waste generation and air toxics regulation. The work is being performed as an integral part of B&W`s development of an advanced low-emission boiler system in a project entitled {open_quotes}Engineering Development of Advanced Coal-Fired Low Emission Boiler Systems (LEBS).{close_quotes} On the basis of these results and other qualitative considerations, the B&W Limestone Injection With Dry Scrubbing (LIDS{sup {trademark}}) process was selected for further development and evaluation in B&W`s LEBS project. The B&W LIDS process is a limestone-based furnace injection/dry scrubbing SO{sub 2} removal process. The process comprises the cost-effective integration of three commercially-proven flue gas cleanup technologies: furnace limestone injection, dry scrubbing, and pulse-jet fabric filtration. This paper describes the results of the B&W Phase I LIDS process development and evaluation. Highlights include: (1) Results of pilot-scale testing performed to demonstrate the feasibility of exceeding the B&W LEBS project SO{sub 2} removal goal of 97% with a fully-integrated LIDS process under cost-effective operating conditions; (2) Mercury removal data. Mercury emissions from coal-fired power plants are a matter of intense debate. It seems likely that mercury emissions will be regulated in some manner in the latter half of the decade; and (3) Results of a LIDS solid by-product engineering study on disposal characteristics and possible utilization specifications. B&W is aggressively pursuing ways to reduce or utilize the solid waste produced by its various FGD processes-including the LIDS process-through a variety of development programs.
