Summary:PURPOSE:To increase the rate at which calcium is utilized and enhance the efficiency of dechlorination and desulfurization by a method wherein water slurry of a specific amount of calcium compound is mixed with a chlorine-containing combustible material and a combustor is loaded wit the mixture for combustion. CONSTITUTION:To burn a chlorine-containing combustible material 1 in a combustor 19 with a dust collector, to part or all of the combustible material 1 water slurry of a calcium compound 8, for which quicklime or slaked lime is preferable, is added in a manner that the number of moles of the calcium becomes one to three times the number of moles in the combustible material 1 (sulfur + 1/2 chlorine) and mixed. The combustor 19 is loaded with the resulting mixture. That is, a calcium compound 8 is put into a preparation tank 12 together with water 13 to form a slurry. On the other hand, the combustible material 1 is crushed by a crusher 6, put in a mixer 7 together with the slurry and mixed; then cured in a curing tank 15 and thereafter put into the combustor 19. Even for a smaller molar equivalent of a calcium compound against chlorine and sulfur, this method enables achieving a high rate of dechlorination.
