Dilute Phase an overview ScienceDirect Topics

For dilute phase conveying the minimum conveying air velocity is about 11 m/s, which is just a little lower than that for the fly ash shown in Fig. 12.1a.Because the material conveys so well, however, the transition to low-velocity dense phase conveying is occurring, with increase in air supply pressure, and as a consequence, the material is conveyed at a solids loading ratio of about 60 and
