Patent number: 9581332Abstract: A burner combustion method is employed in which at least two burners (2) are disposed opposite each other in a furnace (1) so as to cause combustion, the method comprising: cyclically changing at least one of a flow rate of a fuel fluid and a flow rate of an oxidant fluid supplied to the respective burners (2) while cyclically changing a concentration of oxygen in the oxidant fluid thereby cyclically changing an oxygen ratio obtained by dividing a supply oxygen amount by a theoretically required oxygen amount, whereby, the burners (2) are made to cause combustion in a cyclical oscillation state, wherein with respect to the cyclical change in an oscillation state of the burners (2), a phase difference is provided between a cyclical change in an oscillation state of at least one burner (2) and cyclical changes in oscillation states of other burners (2).Type: GrantFiled: June 28, 2011Date of Patent: February 28, 2017Assignee: TAIYO NIPPON SANSO CORPORATIONInventors: Yasuyuki Yamamoto, Kimio Iino, Yoshiyuki Hagihara, Tomoyuki Haneji

Patent number: 8071015Abstract: Disclosed is a process of producing a porous metal body containing a metal component which is likely to be oxidized, by which process the amounts of residual carbon and residual oxygen therein are decreased, and by which the performance of the product porous body can be largely promoted. The process for producing a porous metal body by sintering a material of the porous metal body, which material is obtained by coating a slurry containing a metal powder and an organic binder on an organic porous aggregate, comprises a defatting step of treating the material of the porous metal body at a temperature not higher than 650° C.Type: GrantFiled: March 17, 2009Date of Patent: December 6, 2011Assignee: Taiyo Nippon Sanso CorporationInventors: Tomohiro Wada, Tomoyuki Haneji, Shinichi Takahashi, Kiichi Kanda, Kenichi Watanabe
