    • [PROBLEMS] To provide among others a method of removing unburned carbon from fly ash that enables stable performance regulation according to the properties of fly ash while attaining reduction of apparatus cost. [MEANS FOR SOLVING PROBLEMS] Water is added to fly ash to thereby obtain a slurry. A capturing agent is added thereto and fed into static mixer (4) or venturi tube (24) or the like to thereby apply shear force. A frothing agent is added to thereby realize frothing, and unburned carbon of the fly ash is stuck to froths, attaining surfacing. The frothing agent and air may be fed together with the slurry and the capturing agent into the static mixer or the like. The number of serially disposed static mixers and relevant units is adjusted in accordance with variation of the properties of fly ash, and the number of in-parallel disposed static mixers and relevant units is adjusted in accordance with required processing capacity. As the static mixers, use can be made of those equipped with guide vane compartment (4b) including multiple guide vanes (4d) and capable of converting the slurry, etc. to a helical flow and equipped with current cutter compartment (4c) capable of applying shear force to the slurry, etc. by means of multiple mushroom-shaped projections (4e).

    • [PROBLEMS] To effectively utilize coal ash while lowering the concentration of mercury in a gas discharged from a cement kiln. [MEANS FOR SOLVING PROBLEMS] Coal ash from a thermal power plant or the like is received by a system for producing cement. The received coal ash is divided into ash and unburnt carbon. The ash thus divided is utilized as a material for cement in the system for producing cement, while the unburnt carbon thus divided is utilized in the system for producing cement depending on the concentration of mercury in a gas discharged from a cement kiln of the system for producing cement. In the case where gags discharged from the cement kiln of the system for producing cement contains mercury at a high concentration, it is possible that the unburnt carbon in the coal ash, which contains mercury localized therein, is not fed into the system for producing cement but processed outside the system for producing cement or the unburnt carbon is fed in a controlled amount into the system for producing cement. Mercury is removed form the thus separated unburnt carbon and the unburnt carbon, from which mercury has been removed, can be used as a fuel in the system for producing cement.
    • [问题]为了有效利用煤灰,同时降低从水泥窑排出的气体中的汞浓度。 解决问题的方法来自火力发电厂等的煤灰由用于生产水泥的系统接收。 接收的煤灰分为灰分和未燃碳。 这样分配的灰被用作用于生产水泥的系统中的水泥的材料,而未分配的未燃碳被用于生产水泥的系统中,这取决于从系统的水泥窑排出的气体中的汞浓度 生产水泥。 在从水泥制造用水泥窑排出的水泥含有高浓度的汞的情况下,将含有汞的煤灰中的未燃烧炭不可能进入生产水泥的系统 但是在用于生产水泥的系统外加工,或者将未燃碳以受控的量进料到用于生产水泥的系统中。 从这样分离的未燃碳去除汞,并且从其中除去汞的未燃碳可用作生产水泥的系统中的燃料。
