1000MW火力发电厂正压浓相气力输灰系统堵管问题探究

Study on the Problem of Blocking Pipe in the Dense Phase Pneumatic Conveying System of 1000 MW Thermal Power Plant

正压浓相气力输灰是目前大型火力发电厂的主要输灰技术。虽然该系统的性能优良,但实际运行中也存在堵灰问题。因此,分析了造成堵管的各种原因,并探究了相应的解决方法。

The positive pressure dense phase pneumatic conveying ash is the main power transmission technology of large thermal power plant. Although the performance of the system is good, but the actual operation of the ash problem is also exist. Therefore, this paper analyzes various reasons causing the blockage, and explores the corresponding solution.
