Abstract

Abstract: Aiming at the higher energy consumption and serious pipeline wear of pneumatic ash conveying system of large thermal power unit, the reasons were analyzed. According to the relation between the flow characteristics of gassolid twophase fluid and its stable transportation flow field, a novel multipump micro positive pressure dense phase pneumatic ash conveying system was designed. The system had been researched and tested in a 600MW unit, and the test result shows that the designed system can reduce the energy consumption and weaken the pipe wear.
