摘要
采用高温燃烧水解-氟离子选择电极法,考察江苏省13个地级市主要燃煤电厂入炉煤中氟的分布及在实验室静态燃烧过程中的迁移规律和分布特征。氟的含量范围为35~248μg/g,平均值为134μg/g,分布较为集中,以中氟煤、低氟煤为主,所占比例为68.6%。氟在静态燃烧过程中绝大部分以气态氟形式析出,气态氟析出率在56.26%~94.32%之间,平均值为85.23%。
The distribution of fluorine in coal from major coal-fired power plants in 13 prefecture-level cities in Jiangsu Province was investigated by using high temperature combustion hydrolysis-fluoride ion selective electrode method,as well as the migration of fluorine during static combustion in the laboratory.The content range and average content of fluorine was(35~248)μg/g with an average of 134μg/g,and the distribution was relatively concentrated,with medium fluorine coal and low fluorine coal accounting for 68.6%.Most of the fluorine in the feed coal evaporated in the form of gaseous fluorine during static combustion,and the evaporation rate of fluorine was between 56.26%~94.32%,with an average of 85.23%.
