摘　　要：本文就作者自行研制的颗粒叶轮流量计用于测量循环流化床物料循环流率进行了研究．证明将叶轮颗粒流量计装入循环床的下料管密相段内，可准确地测量物料循环流率．与此同时，也与色点示综法和压差法等常规方法进行了比较，证明叶轮法是一种准确、可靠、简单、且可在线的测量方法。A Bulk Solids Flowrate Turbine Meter（BSFTM） developed by the authors was used to measure the solids reclrculating flowrate of circulating fluidized beds．The results show that it can measure the solid flowrate accurately by placing the device in the dense solids phase in the standpipe of a circulating fluidized bed．As compared whth the colored tracer method and pressure drop method，the results indicate that the turbine method is more accurate,reliable and simple for on－line use.
