在火电厂水力输灰系统结垢机理及灰水静态溶出特性研究的基础上，针对电厂灰中氧化钙含量丰富的神府东胜煤开展了水力输灰系统结垢的动态模拟研究。分别对灰成份、管道材质、灰水流速、输灰水回收率、灰水在灰库的停留时间、灰水在输灰管中的运行时间以及沿程对结垢的影响等因素进行了分析讨论。试验结果表明：采用橡皮管材、提高灰水流速、提高输灰水回收率及灰水在灰库停留时间均可降低灰水结垢速率；当灰水在输灰管中流动时，起初结垢速率比较低，但随着时间的延长，结垢速率逐渐增加直至达到一稳定值；沿程结垢情况和沿时结垢情况不同。在入口处结垢速率较高，但它沿管程以指数规律衰减 Based on the study of fouling mechanism and ash-water static leaching characteristics of hydroturbine system in power plant, a dynamic simulation study of scaling of hydroturbine system was carried out for Shenfu Dongsheng coal rich in calcium oxide in power plant ash. Factors such as ash content, pipe material, flow rate of gray water, recovery rate of gray water, residence time of gray water in ash warehouse, running time of gray water in ash conveying pipe and influence of scale on scaling were analyzed respectively discuss. The test results show that: the use of rubber pipe, to improve the flow rate of gray water to improve the ash recovery rate and gray water retention time in the ash can reduce the rate of gray water scaling; when the gray water flow in the ash pipe, the initial scaling The rate is relatively low, but as time goes by, the rate of fouling gradually increases until it reaches a steady value; fouling along the process and fouling along the rim are different. Fouling rates are higher at the entrance, but decay exponentially along the tube
