Using modified IEA-CFBC(International Energy Association-Circulating fluidized bed combustion) model, a 2 MWe oxy-fuel CFBC boiler is simulated and analyzed as a promising solution to reduce greenhouse gas emission from coal power plants. This study evaluated and compared the oxy-combustion characteristics of various coals. Also, the effects of CO2 concentration (71–79 vol%), bed temperature (850°C) and coal properties on combustion efficiencies, CO2 concentration, acid gas emissions were analyzed. Because of their higher N2 and S content, sub-bituminous and bituminous coals were found to have SOx and NOx concentrations higher than those of anthracite. These simulation results from Oxy-fuel CFBC simulation of various coals can be used as operating parameters for design and development of commercial Oxy-fuel CFBC boilers.

2MWe CFB锅炉富氧燃烧行为的数值研究

使用改进的 IEA-CFBC（国际能源协会-循环流化床燃烧）模型，对 2 MWe 氧燃料 CFBC 锅炉进行了模拟和分析，作为减少燃煤电厂温室气体排放的有前景的解决方案。本研究评估和比较了各种煤的氧燃烧特性。此外，还分析了 CO2 浓度 (71–79 vol%)、床温 (850°C) 和煤特性对燃烧效率、CO2 浓度、酸性气体排放的影响。由于 N2 和 S 含量较高，亚烟煤和烟煤的 SOx 和 NOx 浓度高于无烟煤。这些来自各种煤的富氧燃料 CFBC 模拟的模拟结果可用作设计和开发商业富氧燃料 CFBC 锅炉的运行参数。
