Research on the stability of low fluorine content coal quantity
FU Hao
Abstract：The emission of harmful elements from coal combustion is an important environmental pollution problem faced by China.Commercial coal with a dry fluorine content exceeding 200 μg/g cannot be imported,sold,or trans-ported over long distances.Therefore,accurate determination of fluorine content in coal has attracted high attention.The stability study of low fluorine content coal can establish a scientific,reasonable,and feasible traceability bench-mark for relevant enterprises.Based on the current distribution of fluoride levels in coal for sale,two low fluoride coal samples with different levels were selected to study the stability of fluoride content in coal.Prepare and package coal samples according to national standards,study the packaging and storage methods of two fluorine series coal samples after opening the bottle,and prove the uniformity of the fluorine series coal samples in the two types of coal through uniformity testing.Experimental results have shown that using brown opaque glass bottles for packaging can meet the requirements of sample packaging.After opening the bottle,it can be stored at room temperature in a cool and dry place to meet the storage requirements of the sample.
