摘要： A method, system and apparatus for a low bed pressure drop circulating fluidized bed (CFB) boiler associated with fast bed CFB combustion are disclosed. The CFB boiler may be operated according to the following set of conditions. In an upper area of a combustor of the boiler, a flow pattern of the two-phase gas-solid flow may be placed in a fast bed fluidization state. The combustor temperature may be within a range of 850° C.-930° C. The fluidizing air velocity may be within 4 m/s and 6.2 m/s. An average size of a bed material in the combustor may be smaller than 300 μm. The gas-solid flow above of the secondary air inlet in the combustor may be kept in the fast bed fluidization state while maintaining a solid concentration of between 1 kg/m3 to 5 kg/m3. An inventory of bed material per unit area and/or the pressure drop in the combustor may be less than 8 kPa.
摘要翻译：公开了一种与快速床CFB燃烧相关的低床压降循环流化床（CFB）锅炉的方法，系统和装置。 CFB锅炉可以根据以下条件进行操作。在锅炉的燃烧器的上部区域中，两相气体 - 固体流的流动模式可以放置在快速床流化状态。燃烧器温度可以在850℃-93℃的范围内。流化空气速度可以在4m / s和6.2m / s之内。燃烧器中的床料的平均尺寸可以小于300μm。燃烧器中的二次空气入口上方的气固流可以保持在快床流化状态，同时保持在1kg / m3至5kg / m3之间的固体浓度。每单位面积的床材料和/或燃烧器中的压降的清单可以小于8kPa。
