摘要： PROBLEM TO BE SOLVED: To detoxify an asbestos-containing material while ensuring safety to workers and make the effective use of fuel energy used for the detoxification and the detoxification processing-received asbestos. SOLUTION: After an asbestos-containing material is pulverized to be 90 μm or larger and 5 mm or smaller in size, the pulverized material is mixed with liquid fuel to generate slurry, and then the slurry is sprayed into a cement kiln through a main burner or a slurry-exclusive burner. After the asbestos-containing material is mixed with the liquid fuel, the material is pulverized to be 90 μm or larger and 5 mm or smaller in size, and the slurry thus generated can be sprayed into the cement kiln. As the asbestos-containing material is handled in a slurry state, the asbestos is prevented from scattering to ensure safety to workers, and the liquid fuel itself contained in the slurry burns to form a high-temperature frame, and the asbestos is denatured to be a harmless material. A waste oil as the liquid fuel is added at a rate of 20 mass% or larger and 500 mass% or smaller to the asbestos-containing material. The slurry is preferably sprayed at a speed of 10 m/s or larger and 50 m/s or smaller. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To efficiently remove unburned carbon from fly ash and to attain effective utilization of the fly ash and removed unburned carbon. SOLUTION: Water is added to the fly ash to obtain a slurry. A collector is added to the slurry and shearing force is applied to the slurry and the collector to attain surface modification. Then the mixture is subjected to flotation operation at which the unburned carbon of the fly ash is attached to froth and is surfaced. Application of the shearing force to the slurry and the collector can be carried out by means of a submerged agitator whereby agitation power of 0.7 to 10kWh/m 3 per unit quantity of slurry is applied. Fly ash concentration of the slurry is in a range of 3 to 50 wt.% and amount of the added collector is in a range of 5 to 100 wt.% based on the amount of the unburned carbon of the fly ash. The unburned carbon separated by flotation can be used as fuel and the fly ash (a product) having its unburned carbon content reduced to 1 wt.% or below can be used as a cement mixing material or a raw material for production of lightweight aggregate.
