摘要： The present invention provides industrially advantageous production method and production apparatus, with respect to production of a halogen oxyacid solution. There is solved by a method for producing a halogen oxyacid solution, comprising continuously supplying an organic alkaline solution and halogen to a static mixer and mixing them, to thereby continuously obtain a halogen oxyacid generated.

摘要： A process for reforming the fly ash, including the heating step that heats a raw fly ash powder containing the unburned carbon at a temperature of 780 to 1000° C. to decrease the amount of the unburned carbon contained in the raw fly ash powder; the classifying step that introduces the heat-treated fly ash containing the unburned carbon in decreased amounts obtained through the heating step into a classifying apparatus in the state of being heated at a high temperature so as to separate the fly ash into a coarse powder and a fine powder; the fine powder recovering step that recovers the fine powder of the heat-treated fly ash obtained through the classifying step by using a dust-collecting apparatus; and the milling step that mills the coarse powder of the heat-treated fly ash obtained through the classifying step until a 45 μm sieve residue becomes not more than 34% by mass, and then recovers the milled powder.

摘要： A process for reforming the fly ash, including the heating step that heats a raw fly ash powder containing the unburned carbon at a temperature of 780 to 1000° C. to decrease the amount of the unburned carbon contained in the raw fly ash powder; and the cooling/classifying step that introduces the heat-treated fly ash in a state of being maintained at a high temperature as obtained through the heating step into a cooling/classifying apparatus so that the fly ash is separated into a fine grains and a coarse grains; wherein the cooling/classifying apparatus 3 used in the cooling/classifying step has a basic structure in which the gas flow for classification is introduced from the lower side and the gas flow Z for cooling/classification introduced into the apparatus is then discharged from the upper side; the heat-treated fly ash is brought into contact with the gas flow Z for cooling/classification, the fine grains contained in the heat-treated fly ash is lifted up and discharged out of the apparatus while the coarse grains contained in the heat-treated fly ash is allowed to stay in the apparatus 3, and the fine grains and the coarse grains are separated and cooled; and the fine grains discharged from the apparatus 3 is recovered by using a dust-collecting apparatus, and the coarse grains is recovered from the apparatus 3.
