人类活动产生的二氧化碳主要是由化石燃料燃烧驱动的，目前的能源需求状况没有迹象表明这种情况在不久的将来会发生变化。因此，在使用化石燃料时，越来越有必要找到减少这些排放的方法。二氧化碳捕获和储存似乎是最有希望的办法之一。所有CCS技术都涉及生产几乎纯的CO2流，或者通过以某种方式将其从烟道气中浓缩，或者通过使用纯氧作为燃烧气体。后一种选择，即氧燃料燃烧，现在已经对煤粉燃烧进行了很好的研究，但迄今为止，在氧燃料循环流化床燃烧（CFBC）的情况下，受到的关注相对较少。最近，在CanmetEnergy的一个100千瓦的试验装置中，对氧燃料流化床进行了研究，该试验装置采用烟气循环。结果强烈支持这样的观点，即该技术提供了空气燃烧FBC的所有优点，但有一个可能的例外..
Anthropogenic CO2 production is primarily driven by fossil fuel combustion, and the current energy demand situation gives no indication that this will change in the near future. In consequence, it is increasingly necessary to find ways to reduce these emissions when fossil fuel is used. CO2 capture and storage (CCS) appears to be among the most promising approaches. All of the CCS technologies involve producing a nearly pure stream of CO2, either by concentrating it in some manner from the flue gases or by using pure oxygen as the combustion gas. The latter option, oxy−fuel combustion, has now been well studied for pulverized coal combustion, but to date has received relatively little attention in the case of oxy−fuel circulating fluidized bed combustion (CFBC). Recently, oxy−fuel FBC has been examined in a 100 kW pilot plant operating with flue gas recycle at CanmetEnergy. The results strongly support the view that this technology offers all of the advantages of air-fired FBC, with one possible exception...
