PARTICLE DEPOSITION CHARACTERISTICS IN ENTRAINED FLOW COAL GASIFIER

Abstract

Cold state experiment and numerical simulation are carried out to study particle eposition process. The deposit mass can be divided into two parts, one directly ollides with the wall and the other is brought by the backflow. The deposit flux ncreases with the increase of gas flow rate or water flow rate or both, and decreases ith the increase of the central channel gas flow rate.
