摘要
从多相流理论出发,分析了循环流化床燃烧器内流体流动、传递过程及化学反应特性,说明了多相流体力学模型可以为该类反应器的设计和放大提供许多有益的信息 由此可见,开展循环流化床内多相流体力学模拟是缩短过程开发周期、加快工业化进程的一种有效途径。
The hydrodynamic model of circulating fluidized bed combustors, derived from the theory of multi-phase flow, is introduced in this paper. Based on this hydrodynamic model, the gas-solid flow, transport, and reaction characteristics in the cornbustors are clearly described . In literatures, the computational results are in good agreement with experimental data and also provide many available information of the scale - up and design for the circulating flu-idized bed combustors.Therefore, the hydrodynamic simulation is an effective method lo shorten the period of process development and to speed up from small scale to the industrial pace.
