摘要
二次风的加入使得循环流化床锅炉内的流体动力学特征更加复杂,进而影响炉内的燃烧、换热以及气体排放等。本文详细介绍了循环流化床二次风引入后流体动力学方面的研究现状,指出了目前存在的问题及努力的方向。
Addition of secondary air will lead to more complex gas-solid hydrodynamics inside the riser of a circulating fluidized bed （CFB） boiler. As a result, combustion, heat transfer and gaseous emissions will change compared to the CFB boilers without secondary air injection. The current thesis discusses the status quo of researches and applications of the hydrodynamics in CFB boilers when the secondary air is employed. The existing problems and orientations are pointed out for further study.
