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.

[Means to Achieve the Object]The electrostatic separation method and the electrostatic separation device each of which separates unburned carbon ash contained in the coal ash by an electrostatic force, wherein: a substantially flat plate lower side electrode and an upper side electrode disposed above the lower side electrode and including a high dielectric resin element are disposed; a separation zone formed by an electrostatic force is formed by generating a DC electric field between the lower side electrode and the upper side electrode where one of the lower side electrode and the upper side electrode is a positive polarity, and another electrode is a negative polarity; and the unburned carbon ash in the coal ash supplied to the separation zone is separated.
摘要:
A method and system for hydrolyzing cellulose and/or hemicellulose contained in a biomass into monosaccharides and oligosaccharides by using high-temperature and high-pressure water in a subcritical condition is provided. In hydrolyzing cellulose or hemicellulose into saccharides by using high-temperature and high-pressure water in a subcritical condition, a large amount of slurry is cooled into a condition below the subcritical condition by subjecting the slurry contained in a pressure vessel under a high-temperature and high-pressure condition to flash evaporation in a pressure vessel charged with a slurry of a cellulosic biomass and heated halfway. It is possible to prevent saccharides from degrading into organic acids and to save energy by recovery of thermal energy. The cellulosic biomass is charged into a water-permeable vessel and then the water-permeable vessel is encapsulated into the pressure vessel together with water.
