Experimental Study on Vertical Dilute Phase Gas Conveying

Abstract

Abstract: An experimental study of vertical gas conveying of Geldart-D powder as a dilute phase is
performed ina pipe of length 22 m and internal diameter 0.05 m using a fluidized blow tank
at gas velocity ranging from 5 m.s-1to 13m.s-1 and loading ratio up to about 30. The
characteristics of gas conveying, such as pressure drop, thechoking velocity and the
minimum primary velocity of the fluidized blow tank, are discussed in detail.

Key words: Geldart-D particle, dilute gas conveying, choking, pressure drop
