| 摘 要： | 在讨论脉动燃烧对传热特性影响的基础上，基于脉动流化燃烧概念，试验研究了脉动流化床中的传热特性，得到不同空截面风速、静止床层高度和声波扰动下的传热系数，并与同一运行参数条件下非脉动流化床及纯气流脉动燃烧器中的传热特性进行对比．总结影响脉动流化床传热特性的各种因素，分析不同运行参数对传热的影响作用．

| Abstract: | Based on an overview of the pulsating combustion on heat transfer characteristics and the concept of pulsating fluidized bed, the heat transfer characteristics of a pulsating fluidized bed were investigated experimentally and the heat transfer coefficients under different superficial gas velocities, initial bed material heights and acoustic properties were obtained and analyzed. The resuits were compared to those from a bubbling fluidized bed and a pulsating combustor under similar operating conditions. And then the various factors affecting the heat transfer characteristics in pulsating fluidized bed were generalized and the effect of different working parameters on the heat ransfer were analyzed. |
