Thermal effect on fluorine emission in coal and clay minerals

Thermal effect on fluorine emission in coal and clay minerals Fluorine in coal is important because of not only its association with indicators of mineralization, but also environmental concerns relevant to the health of plants, animals and humans. In order to analyze the fluorine emission characteristics, this paper summarizes the laboratory data from a number of Chinese literatures of fluorine emission of coal and clay minerals for high-temperature heating. The range of temperature to which specimens have been exposed is room temperature to 1200 °C. The variation of fluorine emission has a significant increase with increasing temperature between the ranges 400–1200 °C, especially above 600 °C. Besides, environmental humidity has obvious influence on fluorine releasing. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Environmental Earth Sciences Springer Journals

Abstract

Fluorine in coal is important because of not only its association with indicators of mineralization, but also environmental concerns relevant to the health of plants, animals and humans. In order to analyze the fluorine emission characteristics, this paper summarizes the laboratory data from a number of Chinese literatures of fluorine emission of coal and clay minerals for high-temperature heating. The range of temperature to which specimens have been exposed is room temperature to 1200 °C. The variation of fluorine emission has a significant increase with increasing temperature between the ranges 400–1200 °C, especially above 600 °C. Besides, environmental humidity has obvious influence on fluorine releasing.
