摘要
通过实验,对GB 212-2001中规定的灰分测定灼烧时间进行了探讨,认为较年青烟煤灼烧30 min所得结果与缓慢灰化法准确度虽然有显著性差异,但小于同一化验室的允许差,对所试验煤种可用于实际工作中。
Relevant experiments of ignit shows that there is rather significant bituminous, but the difference is below ion time of ash content test were conducted according to GB/T 212-2001. The result difference between slow-ashing method and 30 min-ashing method for the younger the permissible value in the same laboratory. The improved fast-ashing method is thought to be suitable for the testing coals in the actual testing process.
