    On a weight basis, it only achieves the same desulfurization efficiency obtained with D1 limestone if Do is added in larger amounts, approximately 1.5 times more. That means 10 t D1 limestone/100 t of coal; while Do needs 15 t/100 t of coal. The same occurs in relation to energy consumption, considering sensible heat and calcination heat (calcination of limestone is a highly endothermic ...
