Fluiding Characteristics of Pulverized Coal in Fluidization & Injection Jar

Abstract:

The fluiding characteristics of pulverized coal in fluidization & injection jar were studied systematically with the conveying property testing equipment of pulverized coal designed by ourselves. Results show that the fluidization process of pulverized coal in fluidization & injection jar is a progressive process. The necessary condition of fluidization for pulverized coal in fluidization & injection jar is that the actual fluiding velocity exceeds the theoretical fluiding velocity. According to the moving state of pulverized coal particles in fluidized and injection jar, the fluidization process of pulverized coal consists of three stages of static bed, fluidization bed and gas flow bed.
