B&W’s circulating dry scrubber (CDS) technology is ideal for small footprints and big expectations for SO2 removal.
B&W is the exclusive North American licensee for Enviroserv’s circulating dry scrubber technology (CDS). CDS technology is designed for smaller units with limited space or which have site-specific needs and fire medium- to high-sulfur coals.
Benefits of a CDS:
• High SO2 removal efficiency
• Integral SO3, HCl, HF, mercury, heavy metals, dioxins and furans, and PM2.5 emissions reduction
• Fuel flexibility to handle higher sulfur coals
• Low capital cost
• Low auxiliary power use
• Low operational and maintenance costs
• Dry reagent preparation and recycle system operation
• Low fresh water consumption
• Integral consumption of plant waste water streams for zero liquid discharge (ZLD) operation
• Absorbent feed independent of water injection (compared to an SDA)
When integrated with our fabric filter and dry sorbent injection technologies, our CDS offers a packaged approach to particulate, mercury and acid gas control.
We consistently demonstrate the ability to successfully execute innovative solutions for our customers, from new equipment to large, complex full-scope engineering and construction projects.
An extensive network of worldwide regional service centers, field service engineers and technical support personnel are available to provide the customized service and aftermarket solutions for your requirements.
B&W provides CDS system for Alliant Energy’s Lansing Station
B&W optimizes its circulating dry scrubber design for each application. This approach provides the end
user with an optimized system to reduce long-term power and lime consumption, while providing reliable operation across wide load and fuel ranges, along with lower maintenance costs. See a description of this B&W project at Alliant Energy’s Lansing Station.
