对四种不同的颗粒尺寸、两种尺寸的传热探针和从30°C到约900°C的几个温度测量了快速流化床的壁的传热。对其他研究者的实验数据进行了批判性的分析，并与目前的数据进行了比较。提出了一个机械模型来解释设计和操作参数之间的相互依赖关系。本文提出了循环流化床燃烧器床壁传热的计算公式。
Heat transfer to the wall of a fast fluidized bed has been measured for four different particle sizes, two sizes of heat transfer probes and several temperatures from 30°C to about 900°C. A critical analysis of experimental data of other investigators is presented and compared with the present data. A mechanistic model is presented to explain the interdependence of design and operating parameters. Equations are presented for prediction of bed-to-wall heat transfer in circulating fluidized bed combustors.
