也谈烧成系统中煤粉水分、细度及其可用热值

Discussion on coal moisture, fineness and net caloric value in burning system

从水泥熟料烧成系统稳定运行方面考虑,有效控制煤粉的燃烧特性、发热量、灰分、细度和水分等参数非常重要。详细分析了煤粉水分,煤粉细度和煤粉热值及其影响因素,在此基础上,介绍熟料烧成系统中使用煤粉时对其水分、细度和可用热值的分析和控制指标。

Considering stable operation of cement clinker firing system, it is very important to effectively control the combustion characteristics, heat, ash, fineness and moisture of the pulverized coal. The moisture content of pulverized coal, the fineness of pulverized coal and the calorific value of pulverized coal and its influencing factors are analyzed in detail. On this basis, the analysis and control index of moisture, fineness and available calorific value of clinker firing system when using pulverized coal are introduced.
