Recently, circulating fluidized bed boilers (CFBs) have been evaluated as a good alternative to puverized combustion boilers (PCs) due to their robustness and sensitivity to fuel quality. CFB classified as clean technology have been extensively studied for various fuels availability, uniform temperature distribution, high energy efficiency, and the ability to produce power generation at a lower cost than PC. To improve CFB performances, it is essential to analyze combustion and desulfurization phenomena in CFBC through computational analysis. In this study, IEA(International Energy Agency)-CFBC model was used to describe various performances that could occur in a 2MWe CFB. Combustion characteristics and the effect of Ca/S ratio on desulfurization in the 2MWe CFB combustor were investigated by using 3 different kinds of coals at 800℃, 850℃, 900℃ |
