虽然煤粉燃烧（PCC）仍然是发电行业的主导技术，但投入使用的电厂中有相当一部分是基于循环流化床燃烧（CFBC）的。与PCC相比，CFBC具有特定的优势，特别是在利用低质量煤以及煤与其他燃料（包括废物）的混合物方面。自最初部署以来，CFBC一直在不断发展。近年来，循环流化床锅炉的大型化和超临界蒸汽参数的采用取得了重大进展。CFBC系统的工程设计和操作也得到了优化，从而提高了工厂的可靠性和可用性，以及工厂的经济性。循环流化床技术正在成为PCC系统的真实的竞争者。对于PCC和CFBC锅炉，正在开发产生高纯度CO2废气流以进行碳捕获的富氧燃烧系统。富氧-CFB技术可能比富氧-PC燃烧设计具有一些优势，但在富氧-CFB锅炉的概念和设计开发方面存在挑战。本报告回顾了CFBC技术的最新发展，以及它如何适应碳捕获和储存战略。缩写和缩略语2 IEA CLEAN COAL CENTRE AFT绝热火焰温度CCS碳捕获和储存CFBC循环流化床燃烧CIUDEN Fundación Ciudad de la Energía厘米COE电费CPU碳净化和压缩单元EHE外部热交换器欧盟欧洲联盟FBC流化床燃烧FBHE流化床热交换器FW Foster惠勒HHV高热值IEA CCC国际能源机构洁净煤中心公里公里公斤/平方米每秒千瓦千瓦低高压低热值毫米毫米兆帕兆瓦电兆瓦时兆瓦热国家能源技术实验室，美国PC煤粉PCC煤粉燃烧研发研发TDC技术开发中心t/h吨/小时美国能源部美国能源部挥发性有机化合物挥发性有机化合物体积百分比芬兰VTT技术研究中心WDF废物衍生燃料
While pulverised coal combustion (PCC) remains the dominant technology in the power generation sector, a significant minority of plant commissioned is based on circulating fluidised bed combustion (CFBC). CFBC offers specific advantages over PCC, particularly in the utilisation of low quality coals, and mixtures of coal with other fuels, including wastes. Since its initial deployment, CFBC has continued to evolve. Recently, significant advances have been made in scaling-up the CFBC units and in the adoption of supercritical steam parameters. The engineering designs and operation of the CFBC systems have also been optimised leading to improvements in plant reliability and availability, and plant economics. The CFBC technology is emerging as a real competitor to PCC system. For PCC and CFBC boilers, oxy-fuel combustion systems that produce high purity CO2 exhaust streams ready for carbon capture are under development. Oxy-CFB technology may have some advantages over oxy-PC combustion designs but there are challenges in the development of the concept and design of oxy-CFB boilers. This report reviews the recent developments in CFBC technology and how it fits within carbon capture and storage strategies.
