摘要: 为研究影响煤炭采样验收代表性的因素及更好的指导用煤单位做好煤炭验收,对30家煤炭供应商近一年的供煤情况及验收数据进行了分析.分析发现,同一煤炭供应商全年的煤炭低位热值存在2MJ/kg的差异,该范围内的煤量占全年总煤量的80%左右.由于来煤差异的存在,采样验收过程中存在多种可能影响最终验收结果的因素.本文对影响采样验收的各种因素进行分析并提出了相关建议.此外,对煤质化验结果进行了分析,建立了煤质指标间相关关系的数学模型,可有效指导用煤单位的日常验收.Abstract: The supply situation and acceptance data of 30 coal suppliers in almost a year were analyzed,in order to study the factors which influence the result of coal acceptance.The analysis found that there is 2MJ/kg difference in the Qnet,ar of the coal receipts by coal using enterprises in a year,accounting for 60% of the annual coal.The result of acceptance check will be affected by many uncertain factors in sampling for acceptance test,the factors were analyzed and the author put forward correlated suggestions.The mathematical model of characteristic indexes of coal quality related relationships is built,which can be used to direct daily coal acceptance of coal using enterprises.
