Patent number: 10576412Abstract: A gas treatment device uses a gas to be treated which contains an acid compound that dissolves into water to produce acid and a treatment liquid which absorbs the acid compound to phase-separate, to separate an acid compound from the gas to be treated. The gas treatment device includes an absorber which brings the gas to be treated into contact with the treatment liquid; a regenerator 14 which heats the treatment liquid contacting the gas to be treated to separate an acid compound; and a liquid feeding portion which feeds the treatment liquid contacting the gas to be treated in the absorber to the regenerator. In the absorber, the treatment liquid contacting the gas to be treated phase-separates into a first phase portion having a high acid compound content and a second phase portion having a low acid compound content. The liquid feeding portion is configured to introduce, into the regenerator, the treatment liquid with the phase-separated first phase portion and second phase portion mixed.Type: GrantFiled: April 27, 2018Date of Patent: March 3, 2020Assignees: Kobe Steel, Ltd., NATIONAL UNIVERSITY CORPORATION NAGOYA UNIVERSITYInventors: Akira Kishimoto, Akira Matsuoka, Katsuya Akiyama, Makoto Nishimura, Hiroshi Machida, Tsuyoshi Yamaguchi, Takehiro Esaki, Hirotoshi Horizoe

Patent number: 9157633Abstract: In order to stably operate a boiler using several kinds of solid fuels including depleted ash as fuels, adhesion of ash is suppressed. A calculator (9) preliminarily collects properties of a solid fuel, such as the content rate of ash and the composition of an ash constituent, as data (8). The calculator (9) uses the mix ratio of solid fuels as a parameter and calculates the composition of an ash constituent of the mixed fuels on the basis of the preliminarily measured composition of the ash constituent of each solid fuel. The calculator (9) determines a reference value of the rate of slug by which the ash deposition ratio is reduced on the basis of the relationship between the preliminarily measured ash deposition ratio and the slag ratio. Further, the calculator (9) calculates the mix ratio of each solid fuel using a thermodynamic equilibrium calculation so as to obtain an ash composition in which the slag ratio is not more than the determined reference value.Type: GrantFiled: July 22, 2010Date of Patent: October 13, 2015Assignee: Kobe Steel, Ltd.Inventors: Katsuya Akiyama, Haeyang Pak

Publication number: 20120174836Abstract: A device for reducing ash adhesion in a boiler, includes: a calculator (9) which, in the case of mixing one or more types of solid fuels, calculates and determines the mixing ratio of the solid fuels so that the resultant solid fuel mixture has a slag viscosity not lower than a reference value at a predetermined atmospheric temperature; and fuel supply amount regulators (3a, 3b) which regulate the amount of the solid fuels to be supplied to the boiler based on the mixing ratio as described above. By using this device, ash adhesion in a boiler can be easily and accurately predicted and, therefore, ash adhesion can be reduced even in the case of using various types of solid fuels including a low-grade coal as fuel.Type: ApplicationFiled: October 5, 2010Publication date: July 12, 2012Applicant: Kabushiki Kaisha Kobe Seike Sho (Kobe Steel, Ltd.)Inventors: Katsuya Akiyama, Haeyang Pak
