Abstract In order to analyze difficulties of purified ash pneumatic conveying, the physical characteristics of purified ash, fly ash fine and coarse coal ash are compared. It is found that the particle size and density of purified ash is smaller than fine and coarse coal ash, which has poor mobility and is easy to adhere to the wall. Therefore, this paper improves the equipment from the perspective of enhancing the mobility of purified ash to improve the purified ash conveying capacity. The design selects the silo pump wall fluidisation improvement scheme, reduces the original fluidisation equipment in the silo pump to support the purified ash, and improves the degree of purified ash fluidisation. Improved silo pumps and pneumatic conveying logic are used in engineering practice, which is very good to complete the pneumatic conveying task, there is no material sticking situation occurs. The results show that the improvement of the silo pump wall fluidisation has a better ability to enhance the purified ash pneumatic conveying, and the optimization of the conveying logic of the purified ash pneumatic conveying system also makes the system process more suitable for the purified ash conveying characteristics.
