摘　　要：我国循环流化床(CFB)燃烧技术经过40年的发展,实现了从学习跟踪、创新并跑到全面引领的跨越,形成了以定态设计理论为核心的设计体系,基于流态重构技术开发了能效指标可以与煤粉锅炉相媲美的节能型CFB锅炉。目前我国的CFB锅炉在应用数量、装机容量、污染控制等许多方面达到国际领先水平。本文回顾了CFB燃烧技术在我国的发展历程,总结了CFB燃烧技术的中国创新与中国贡献,并对后续的发展进行了展望,未来应充分发挥CFB燃烧技术燃料适应性广的优势,做好低热值燃料的清洁高效消纳,同时进一步提升CFB锅炉负荷调节速度,并实现0~100%的全负荷运行,推动CFB机组由电量型向功能型转变,助力可再生能源消纳利用和电网安全稳定运行。The circulating fluidized bed(CFB)combustion technology in China has become the world leader after 40-year research and development,and a design system with state specification design theory as the core has been established.The fluidization state reconstruction has also been applied in CFB boilers,which increases the energy efficiency on a par with the pulverized coal boiler.Nowadays,China’s CFB boiler ranks first in the world in many aspects,such as number,unit capacity and emission control.This article reviews the development of CFB combustion technology in China,summarizes the Chinese innovation and contribution,and looks forward to the future development of this technology.In the future,it is suggested to make full use of the wide fuel adaptability of the CFB combustion technology,and use low-heat-value fuel with lower emission and higher efficiency.Moreover,the load regulation speed of the CFB boiler should also be improved and 0~100%load operation should be achieved.The CFB units should transfer from electricity type to function type,so as wo promote the utilization of renewable energy and safe and stable operation of the power grid.
