Latest evolution of oxy-fuel combustion technology in circulating fluidized bed

Abstract

O2/CO2 combustion technology is considered as one of the most promising method to mitigate the greenhouse effect, and the O 2/CO2 CFB combustion technology which combines O 2/CO2 combustion technology with circulating fluidized bed (CFB) combustion technology will extend both their advantages. The latest research findings on O2/CO2 CFB combustion technology are reviewed, the combustion and pollutant emission characteristics are expatiated, its effects on the boiler design are analyzed, the techno-economic assessment are reported and the key issues are indicated in the paper. O 2/CO2 CFB combustion technology has no insolvable bottleneck in its development and due to its economic superiority; it is one of the most important clean coal technologies.
