摘要
内旋流型流化床炉利用非均匀布风产生高温气－固两相旋流，使燃料在炉内运动、相互碰撞、干燥、破碎、燃烧，并可通过改变布风控制燃料加热与挥发份析出速率、燃烧温度与热负荷，适合多种高水分劣质煤及城市垃圾的洁净燃烧，是一种高效低污染流化床燃烧技术。本文研究该型燃烧器床内空气运动、燃烧、传热及排放规律，发展新型清洁燃烧技术。
The Internal Circulating Fluidized Bed (ICFB) Combustor can generate high temperature gas solid two phase swirl by non homogenous air distribution, which lets the fuels in the combustor move, impact, dry, crash, and ignite. The heating rate, gasification rate of the volatile components and the combustion temperature and load can be controlled by adjusting air distribution and various fuels, such as high moisture low grade coals and municipal solid waste (MSW), can be burned in ICFB furnace. ICFB Combustion is a sort of technology of high efficiency and low pollutant emission FBC (fluidized bed combustion). This paper studies the air motion pattern, the mechanisms of combustion, heat transfer and pollution formation, and develops the new clean combustion technology.
