氧煤燃烧的研究与发展 如何从燃煤锅炉中捕获CO2一直是人们研究的课题。 有许多研究。最近,巴布科克和威尔科克斯 公司(B&W)和液化空气(AL),赞助 美国能源部(DOE)的工作已经完成 该技术在1.5兆瓦(5)时的中试评估 MBtu/hr)采用比例模型商用锅炉设备。 氧煤燃烧火焰的稳定性、锅炉和凸起- 锅炉热力性能 与空气/煤相比,NOx的排放水平良好 射击条件.蒸汽发电厂工程 经济评价也表明氧煤燃烧 是一种技术上可行和经济上可行的技术。 B&W和AL公司目前正在美国赞助下。 DOE,承担一个项目,以显著地扩大ap- 氧煤燃烧技术对现有技术的适应性 燃煤锅炉队。成功完成此操作后 开发工作,中试规模的氧煤燃烧试验数据 将可用于应用和放大两个墙- 燃烧沥青的已燃和CycloneTM炉膛锅炉, 次烟煤或褐煤。本文将描述 迄今为止进行的研究、未来的中试规模和扩大 该技术要全面商业化运作。

The research and development of oxy-coal combustion for CO2 capture from coal-fired boilers has been the subject of numerous studies. Recently, The Babcock & Wilcox Company (B&W) and Air Liquide (AL), with sponsorship of the U.S. Department of Energy (DOE), have finished a pilot-scale evaluation of the technology at 1.5 MWth (5 MBtu/hr) using scale model commercial boiler equipment. The oxy-coal combustion flame stability, boiler and convec- tive pass heat transfer, boiler thermodynamic performance and NOx emission levels compared favorably to the air/coal firing conditions. A steam generating plant engineering and economic evaluation also showed that oxy-coal combustion is a technically feasible and economically viable technology. B&W and AL are currently, with sponsorship from the U.S. DOE, undertaking a project to significantly broaden the ap- plicability of oxy-coal combustion technology to the existing fleet of coal-fired boilers. Upon successful completion of this development effort, pilot-scale oxy-coal combustion test data will be available for application and scale-up to both wall- fired and CycloneTM furnace boilers that burn bituminous, sub-bituminous or lignite coal. This paper will describe the research performed to date, future pilot-scale and scale-up of the technology to full-scale commercial operation.
