摘要
对煤中氟的含量分布、赋存状态等地球化学特征进行了综述,分析了煤炭燃烧过程中氟的迁移转化行为与释放特性,指出煤中氟的燃烧释放不仅与氟的物理化学性质有关,更取决于煤中氟的浓度、赋存状态及燃烧工况等因素.进一步讨论了天然钙基材料燃煤固氟技术及燃煤氟污染控制的研究现状.
Fluorine is a harmful element in coal and released in coal combustion. The geochemistry properties of content distribution and the occurrence modes of fluorine in coal are summarized. The behavior of migration and evolution of fluorine in coal combustion are analyzed. The research results show that the combustion and evolution of fluorine in coal is not only associated with its physicochemistry properties directly, but also relate to the factor of concentration, occurrence modes and combustion condition, etc. The technology of fluorine retention with calcium-based materials and the research state of fluorine pollution control in coal combustion is discussed further.
