Design Features
Clean Burning
- Low emissions are a key benefit of our CFB technology, allowing them to meet the strictest environmental standards
- Our CFBs stage the combustion process and operate at low combustion temperatures while giving the fuel long burning times, resulting in naturally low nitrogen oxide (NOx) formation and high combustion efficiency
- They can also capture the fuel’s sulfur as the fuel burns by using low-cost limestone and employing selective-non-catalytic reduction (SNCR) to achieve very low NOx and sulfur oxide (SOx) emissions in the most economical way, and in most cases, avoiding add-on pollution control equipment
- The CFB advantage is particularly highlighted in repowering projects. SOx and particulate emissions can often be cut by over 90% and NOx emissions by over 50%. Carbon dioxide emissions are often cut by 25% or more due to the dramatic improvements in boiler and plant efficiency when older equipment is replaced
- For the lowest emissions, our supercritical, once through-unit (OTU) CFB technology can reduce all these emissions another 5-10%, due to its ability to further increase overall plant efficiency
Fuel Flexible
- Fuel Flexibility allows our CFBs to utilize nearly any solid fuel - including waste products that otherwise would have been land-filled – while maintaining the lowest levels of emissions, and the highest equipment reliability and efficiency
- Our fuel experience is unmatched as proven by our capability to design units for even the lowest quality fuels
- Our CFBs give plant owners the flexibility to source fuel from a number of suppliers and industries, improving their fuel supply security while taking advantage of fuel prices and market conditions
Reliability
- Our simple yet advanced CFB designs can achieve the highest plant availability, proven by over twenty million hours of operational experience, even after years of operation. Preventative condition monitoring, expert maintenance, and rapid-response repair work - all supplied by our service teams - help ensure maximum reliability - year after year
- Our long-term operations and maintenance support (O&MS) agreements and our innovative SmartBoiler™ system (an expanding set of intelligent analysis and optimization tools for enhancing plant operation and maintenance) are available to increase your plant’s availability even further
