CRYSTALLINITY, TRUE DENSITY AND INTRINSIC REACTIVITY OF INTERMEDIATE TEMPERATURE COAL CHAR

Lu Jiling Li Yong Yang Xiaoyong Yue Guangxi (Thermal Department of Tsinghua University Beijing) Yam Y lee (ABB Corporate Research Baden Switzerland)  
The true density and crystallinity of char samples of a kind of bituminous vitrinite were measured and studied These char samples were obtained at various temperature and residence time The true density and crystallinity of the residual carbon in the fly ash from a stoker boiler were also investigated The results showed that the crystallinity of coal char samples generated at intermediate temperature increases with an increase in temperature and residence time It also showed that there is a certain relationship between crystallinity, true density and the intrinsic reactivity of coal chars
