<p>PROBLEM TO BE SOLVED: To provide an incinerating facility using a circulating fluidized bed type furnace in which surplus desulphurization agent is circulated and utilized, a feeding amount of the desulphurization agent is reduced, and at the same time a performance of a drying machine is improved or an amount of generated odor is reduced by the circulated ashes. SOLUTION: An ignited ash circulating and utilizing incineration system is employed, a part of incinerated ash (surplus desulphurization agent) is returned back to a specified amount hopper (or a sand layer in the furnace), mixed with dehydrated cake and circulated for utilization, thereby reducing a feeding amount of desulphurization agent, resulting in that a total amount of generated incineration ashes is reduced. Further, a performance of the drying machine is improved by the circulated ashes and an amount of generated odor is reduced.</p> |
