Publication number: 20250043096Abstract: A method for producing a low-molecular fluorine compound, including a decomposition step for heating a microwave absorber by the irradiation with microwaves in a reaction vessel provided with a carrier gas inlet and a decomposed gas outlet and then bringing the heated microwave absorber into contact with particles of a material containing a fluororesin to decompose the fluororesin into the low-molecular fluorine compound, wherein the carrier gas temperature TI (° C.) at the inlet is set to a temperature lower than the temperature TR (° C.) of the heated microwave absorber. Accordingly, a temperature difference can be provided such that the temperature of a produced gas discharged from the reaction vessel becomes lower than the temperature in the decomposition reaction system, i.e., the temperature of the heated microwave absorber.Type: ApplicationFiled: October 25, 2024Publication date: February 6, 2025Applicant: DAIKIN INDUSTRIES, LTD.Inventors: Yasunori TSUKAHARA, Tamotsu TAKAMOTO, Toshihiko OGATA, Masahiro KANNO, Yukari DEGUCHI, Kazuaki FUKUSHIMA, Yosuke KISHIKAWA, Shinya HANDA, Motoshi MATSUI, Daisuke SHIRAKAWA, Yasushi YAMAKI, Masahito YAGISHITA

Patent number: 10837641Abstract: The present invention provides a burner, a combustor equipped with the burner, and a gas turbine, with which it is possible to premix a first hydrocarbon-based fuel (for example, natural gas), a second fuel (for example, hydrogen gas), and combustion air, and to spray into the combustion chamber of the combustor a thin and uniform concentration distribution of the premixed air, and with which it is possible to suppress the amount of NOx discharged. On the upstream side of the premix flow path, hydrogen gas is sprayed from second fuel spray nozzles, which project into the premix flow path, into the flow of the combustion air flowing toward the center from the outer edge of an outer cylinder, whereby a primary air-fuel mixture having a uniform concentration distribution is generated without affecting a low-speed region of the combustion air.Type: GrantFiled: December 25, 2015Date of Patent: November 17, 2020Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Masahiro Ogata, Takeo Oda, Yasuhiro Kinoshita, Kohshi Hirano, Takahiro Uto
