Research Review and Prospects of High-density Circulating Fluidized Beds
高密度循环流化床研究现状及展望

This paper reviews investigations on the high-density circulating fluidized beds, which are compared to those on the low-density circulating fluidized beds. The authors believe that the study on hydrodynamics and other fundamentals of high-density circulating fluidized beds, especially in high-density downer, has a great future. Some key topics about HDCFB which deserve urgent, intensive attention are suggested.
