Abstract
Based on the harmfulness of atmospheric fluorine pollution from coal combustion and the existing problems in fluorine pollution control research,and combining with the distribution of fluorine in Guizhou coal and the comparison analysis of fluorine in coal seam sample and corresponding fluorine in gangue in Liupanshui and Zunyi exploration area,the relationship between metamorphism degree of coal and the fluorine,the relationship between fluorine in coal and the ash content,the relationship between fluorine in coal and alkali metal,the relationship between fluorine and chlorine in coal and other harmful elements were researched,the occurrence form and occurrence law of fluorine in Guizhou coal were investigated,it was indicated that the fluorine in Guizhou coal is mainly in the range of 50 μg/g~180 μg/g(average value:135.6 μg/g),the fluorine is mainly existed as inorganic minerals state.关键词
