<p>PROBLEM TO BE SOLVED: To provide a storing method without aggregatingly storing aggregative dust for storing the dust highly hygroscopic and being aggregated by hydration reaction. SOLUTION: Fly ash cake is once housed in a slurry pit 7 by using a screw conveyor 6, or the like, and the slurry is then transferred to a slurry storage tank 9 by a tube pump 8 to be stored while agitated, which is the storing method of fly ash being the aggregative dust for storing it in a slurry state while preventing the aggregation. In order to enhance the fluidity of the slurry, water or liquid fuel, a denitrating agent such as a urea solution, an acidic or alkaline solution, waste oil or other liquid waste and liquid such as a mixture of these can be added to the fly ash cake or to the tank 9 by using the conveyor 6.</p> |
