摘要

基于已搭建的20 m超高提升管循环流化床(CFB)冷态实验台

以石英砂为CFB床料

系统分析了颗粒粒径、流化风速和提升管压降等因素对过渡区和稀相区颗粒浓度分布规律的影响。结果表明:在过渡区

颗粒浓度衰减系数与压降和流化风速呈反比关系

与床料粒径呈正比关系;在稀相区

颗粒浓度衰减系数与流化风速呈反比

与颗粒粒径呈正比。

Abstract

Based on the established circulating fluidized bed (CFB) cold test platform with 20 m ultra-high riser

quartz sand was used as the bed material to systematically analyze the effects of particle size

fluidization velocity

and riser pressure drop on the particle concentration distribution in the transition zone and the dilute phase zone. Results show that in the transition zone

the attenuation coefficient of particle concentration is inversely proportional to the pressure drop and fluidization velocity

and directly proportional to the bed material size. While in the dilute phase zone

the attenuation coefficient is inversely proportional to the fluidization velocity and directly proportional to the particle size.
