高粘结性煤在电站煤粉锅炉中的燃烧特征

COMBUSTION PERFORMANCE OF HIGH CAKING PROPERTY COAL IN PULVERIZED-COAL BURNING BOILERS AT THERMAL POWER PLANTS

根据试验室研究结果 ,介绍具有强粘结性的古交中煤 (焦煤 )作为动力用煤在电站煤粉锅炉中可能出现的燃烧特性 ,得出了采用挥发分等常规指标判别焦煤燃烧特性应进行的修正及其修正系数。提出了燃用焦煤应注意的事项 。

Based on study results in laboratory, the combustion performance may appear in burning Gujiao medium coal (coking coal) with high caking property as coal sort for power-generation in pulverized coal boilers are presented, obtaining correction that must be performed and the correctin coefficient that must be used when using conventional indices such as volatile etc. to judge the combustion performance of coking coal, putting forth points for attention to burn coking coal, as well as how to select reasonable parameters and operating mode of the burning facility.
