Simulation Study on Fluidized Bed Carburizing Layer Depth Mathematic Model 流态化渗碳层深度数学模型仿真研究
In case of an increase in the fluidized gas velocity, static bed layer height and particle diameter there emerges an intensification of the particle internal circulation. 当流化气体速度、静态床层高度和颗粒粒径增加时,颗粒的内循环增强;
On the basis of analyzing the cause of the generation of particle internal circulation in a gas solid fluidized bed further analyzed is the influence on particle internal circulation of the following factors: fluidized gas velocity, static bed layer height and particle diameter and pressure. 分析了气固流化床内颗粒内循环产生的原因,进而,分析了流化气体速度、静态床层高度、颗粒粒径以及压力对颗粒内循环的影响。
By the concept, "combustion portion x," presented in this article is meant the fraction of coal burnt within the fluidized layer. 本文提出了燃煤在沸腾层内燃烧份额x这一概念。
This paper presents the results of an experimental study on the dynamic characteristics of particles in a V type inner circulating fluidized bed, including the kinematic trajectory of the particle inner circulation, the distribution feature of the bed layer inner pressure and fluidization speed, etc. 本文介绍了V型内循环流化床中颗粒动力特性的试验研究结果,包括颗粒内循环的运动轨迹,床层内压力分布特性及流态化速度等。
