Enhanced limestone injection dry scrubbing (E-LIDS{trademark}) development as part of B&W`s combustion 2000 LEBS
- Babcock & Wilcox, Alliance, OH (United States)
Babcock & Wilcox (B&W) is currently developing the Enhanced Limestone Injection with Dry Scrubbing (E-LIDS{trademark}, patent pending) system to be capable of reducing SO{sub x} and particulate emissions significantly below that allowed under the current New Source Performance Standards (NSPS) 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 (Combustion 2000 - LEBS).{close_quotes} The program is sponsored by the US Department of Energy. The overall goal of the DOE`s program is to dramatically improve environmental performance and thermal efficiency of conventional coal-fired power plants. The B&W E-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 ps cleanup technologies furnace limestone injection, dry scrubbing, and pulse-jet fabric filtration. Specific LEBS goals that are addressed by the E-LIDS system are (1) sulfur dioxide emissions less than 0.10 lb/SO{sub 2} MBtu, (2) particulate emissions less than 0.005 lb particulates/MBtu, (3) air toxics emissions significantly reduced, and (4) solid by-product minimized and/or utilized. This paper introduces results of 10 MW E-LIDS testing performed in B&W`s world-class Clean Environment Development Facility to demonstrate the LEBS project SO{sub 2} removal goal of 98% under cost-effective operating conditions. Air toxics measurements of mercury, trace metals, and acid gases are also covered.
