摘 要:分析了中国炼焦商品煤工艺性能现状,主要包括煤岩特征、黏结性和结焦性、灰成分等指标的变化特征,并与部分进口炼焦煤进行对比分析。分析结果表明:国内炼焦煤的炼焦工艺性能优良,煤中有害元素含量较低,但存在全硫含量较高以及煤质稳定性较差等问题;进口炼焦煤质量稳定性较好,硫含量相对较低,但其中某些炼焦煤的炼焦工艺性能较差,个别有害元素含量相对较高。The status of process performance of Chinese coking commercial coal was analyzed, variation laws of indicators like coal petrography, caking property, coking property and coal ash composition were included, comparison analysis with some imported coking coal was done as well.The comparison results showed that: process performance of Chinese coking coal is good, the harmful elements content are relatively low, but problems like high total sulfur content and bad coal quality stability exist;imported coking coal has good quality stability, total sulfur content is relatively low as well, but some of them have bad coking process performance, andindividual harmful elements content is relatively high.
关 键 词:炼焦煤 工艺性能 煤质 变质程度 煤岩特征 煤灰成分
