摘要
本文对循环流化床内飞灰颗粒冲击单根管子的碰撞和磨损问题进行了数值研究.计算出管壁各处受冲蚀的程度,并指出了最大冲蚀的部位,讨论了冲蚀量与烟气速度和颗粒尺寸的关系,并将估计的冲蚀结果与实验结呆做了比较,两者之间能较好的相吻合。
This paper reports on quantitative research concerning impingement of circulating fluidized bed ash particles on individual tubes and the ensuing erosion effect.The extent of tube wall erosion is calculated, the location of heaviest erosion is predicted and the dcpendance of the eroded volume on gas velocity and particle size is discussed. Comparison of prediction and test results show a fairly good fit.
