工业废水水煤浆燃烧特性的热分析综合研究

用TG－DTG－DTA（热重－微分热重－差热）热分析技术研究了工业废水煤的燃烧特性并与煤粉燃烧特性进行了比较，结果表明：工业废水水煤浆在着火温度，燃尽温度方法比煤粉低；水煤浆燃烧速度最大时的湿度略高于煤粉燃烧速度最大时的温度；水煤浆中挥发物与固定碳发热量之比与煤粉基本一致工略高；说明用工业废水生产水煤浆是可行的。

Thermal Analysis on Combustibility of Coal Water Slurry with Industrial Waste Water

Preparation of CWS with industrial waste water is a clean coal technology beneficial to environment protection. The combustibility of CWS with industrial waste water from the coking plant was studied. The TG DTA DTG thermal analysis technology was applied to study the combustibility of coal industrial waste water slurry, the effect of coal quality on the combustibility of coal water slurry, and the difference in combustibility between fine coal and CWS . The result shows that the ignition temperature of CWS is lower than that of fine coal. The temperature at which burning velocity reaches the highest is a little higher than that of fine coal. The ratio of volatile to the heat value of fixed carbon in coal water slurry is the same as or a little higher than that in fine coal. The result also indicates that to produce coal water slurry using industrial waste water is feasible.
