Calcination/carbonation reactions of calcium compound were performed in atmospheric and pressurized thermogravimetri analyzer (TGA). Raw limestone and in limestone with 10%wt of coal ash were used as samples. Calcination rate of re-carbonated CaCO_3 become slower after 5^<th> cycle of calcination/carbonation reactions in atmospheric TGA, and it became uncompleted calcination in pressurized TGA. Ash addition accelerated calcinaton reactions of re-carbonated CaCO_3 in atmospheric and pressurized TGA. Crysitallization of CaCO_3 was suggested to decrease calcination reaction rate of re-carbonated CaCO_3. Ash addition prevented crystallization through reaction of CaO with ash to form calcium aluminosilicate compounds.
