摘　　要：介绍能连续稳定高效运行的颗粒介质气力循环清灰系统 ,包括颗粒介质供料器、传输系统和清灰器结构优化试验研究 ,系统的运行规律证明连续稳定循环清灰可行 。Described in this paper is a pneumatic conveying and filtrating media based ash removal system capable of uninterrupted steady and high efficiency operation. An experimental study aimed at structure optimization has been performed of the granular media feeding device, a transport system and the ash removal device. The operation experience of the above cited ash removal system demonstrates the feasibility of a continuous and stable process of pneumatic conveyor based ash removal. The detailed information presented in the paper can serve as helpful hints and valuable reference data for the development of high temperature ash removal technology based on the use of a moving granular bed filter.
