The grindability of coal is an important parameter in pulverized coal utilities.
煤的哈氏可磨性指数(HGI)是煤磨碎过程中的一个重要参数,为进一步研究单煤及其混煤的磨碎过程和可磨性变化规律,采用哈氏可磨性指数测定仪对俄罗斯煤和平朔煤及这两种煤的不同比例的混煤进行HGI测定,并用激光粒度仪对粉碎后的煤样进行粒度分析。
The machine is simpler and closer to application condition that the blades scrape the seal coating in the aircraft turbine enginge than other methods used in abradability evaluation.
用刮削单位体积涂层所消耗的功评价涂层的可磨耗性。
Hardgrove grindability index(HGI) has been obtained by doing grindability experiments on eleven coals in Zhanjiang Power Plant with regular method;according to the designed parameters of coal-milling of Zhangjiang Power Plant;the feasibility of actual coal-using of Zhanjiang power plant has been concluded;the fuzzy arithmetic to deal with the HGI data has been generalized.
用常规的方法对湛江电厂11种用煤进行哈氏可磨性实验测得哈氏可磨性指数(HGI),利用模糊算法对可磨性指数(HGI)进行数据处理,根据湛江电厂磨煤机的设计参数,最后得出湛江电厂实际用煤的可行性并提出把该算法推广到其他电厂的改进办法。
