摘要
介绍了三种提高褐煤锅炉中速磨煤机制粉系统干燥出力的方法,分析了其系统特征、运行情况及存在的问题,并对优缺点进行对比。结果表明:热一次风蒸汽加热系统布置简单、工程实施难度小、锅炉效率高、成本低、干燥出力提升效果明显。
An introduction is presented to three methods for improving the drying capacity of a medium-speed pulverizing system for lignite-fired boilers,together with an analysis on the system features,operation conditions and existing problems,while their advantages and disadvantages were compared.Results show that the primary hot air steam-heating system is simple in layout,easy to implement,with high efficiency of boiler,low cost of system,and obvious effect in improvement of the drying capacity.
