The release and transformation characteristics of Na/Ca in Zhundong coal under inert atmosphere were studied by using tubular heating furnace based on occurrence modes of Na/Ca containing species. It is found that water soluble Na_w firstly transfers to insoluble Na_re when the heating temperature is lower than 600℃. As the temperature increases, insoluble Na_re transfers back to water soluble Na_w. Large amount of Na releases when the temperature is higher than 800℃. Acid soluble Ca_ac firstly decomposes to CaO when the heating temperature is lower than 700℃, and CaO reacts with other minerals to form insoluble Ca_re. As the temperature increases, insoluble Ca_re transfers to acid soluble Ca_ac and water soluble Ca_w. At the same temperature, the release rate of Ca is lower than that of Na. Moreover, a little amount of acid soluble organic Ca will release when the volatile matter releases.
