摘要： A CO2 recovery method and apparatus for desorbing and recovering carbon dioxide with low energy consumption from a gas discharged from a power generation plant having a boiler and a steam turbine. The adsorption and the desorption of carbon dioxide are performed alternately in two CO2 absorbers and located in a CO2 recovery apparatus, which each hold a carbon dioxide adsorbent. When carbon dioxide is desorbed, steam discharged from an outlet of a steam turbine of a power generation plant is partially branched before introduced into a condenser, and sent to a steam compressor. The partially branched steam is compressed in this compressor, and then sent to a cooling device. By cooling, the steam for desorption is prepared. The steam prepared in the cooling device is supplied into a CO2 absorber to desorb carbon dioxide. Accordingly, waste steam, before it is introduced into the condenser, is usable for desorption.

摘要： The present invention provides an electrostatic separation method and an electrostatic separation device each of which, even in a case where the concentration of unburned components of coal ash produced by a boiler of a coal-fired power plant is as high as 15% to 30%, can stably separate the ash without generating spark, reuse the high unburned component ash as fuel, and reuse the low unburned component ash as, for example, an auxiliary material of concrete. The electrostatic separation device may include a substantially flat plate lower side electrode and an upper side electrode including a high dielectric resin element. A separation zone is formed in a region of electrostatic force between the lower side electrode and the upper side electrode, with one of the electrodes having positive polarity and the other having negative polarity. Unburned carbon ash in the coal ash supplied to the separation zone is separated.

摘要： A method of estimating the hydration reactivity of coal ash with high precision and determining the amount of milling water for obtaining a milling product in funicular form at the stage of milling; and a molding method being free from the problem of adhesion to a pressurization board at the stage of molding after the milling. When any collected coal ash exhibits a corrected basicity ((CaO+Fe2O3+MgO)/SiO2 (weight ratio)) of 0.1 or higher and a reactivity index (corrected basicity/(R2O/Al2O3) (weight ratio)) of 10 or higher, the coal ash as a raw ash is transferred to raw ash silo (2). Otherwise, the coal ash is transferred to waste ash silo (3). The raw ash within the raw ash silo (2) is poured in mill (8), and lime and gypsum are added and further milling water is charged thereto and milled. The amount of milling water is regulated so that with respect to agitator power per weight of material milled by the mill, the ratio of (average of power during 30 to 40 sec after completion of water charging)/(power at idling) ranges from 3 to 4, and so that with respect to agitator power per weight of material milled during 30 to 90 sec after completion of water charging, the ratio of (width of power fluctuation)/(average of power) ranges from 0.1 to 0.3.
