Patent number: 5198312Abstract: A power generation system with flat fuel cells of solid electrolyte construction permits the building up of a large capacity system. There are a train of pile units of flat fuel cells of solid electrolyte disposed in a horizontally extending fuel gas duct. The gas fuel duct supplies to the train of pile units of flat fuel cells fuel gas. Each of said pile units of flat fuel cells has a horizontal flat flow path for the fuel gas disposed above each fuel-side porous electrode sheet of the fuel cell opening freely at two path ends on the opposing side faces of the pile unit. There is a horizontal flat flow path for the oxidant gas disposed beneath each oxygen-side porous electrode sheet separated from the fuel gas flow paths and each connected at two path ends to either a supply line or to an exhaust line for the oxidant gas.Type: GrantFiled: March 13, 1991Date of Patent: March 30, 1993Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Mitsuhiro Irino, Tokuki Satake, Hiroshi Sakai, Masayuki Funatsu, Hisao Haneda, Masaru Ishibashi, Koichi Takenobu, Kiyoshi Watanabe, Kazumi Ogura, Shigeru Ohkura

Patent number: 4754725Abstract: A boiler having a furnace, a tunnel section and a rear gas duct is improved by the fact that a partition wall at right angles to side walls of the rear gas duct is disposed in the rear gas duct to divide it into two passages. A low-pressure reheater is disposed in the divided passage nearest to the tunnel section and has a narrow width. Two partition walls are disposed in the other divided passage parallel to the side walls of the rear gas duct to further divide the passage into three passages. Superheaters are disposed in the further divided passages close to the side walls and a high-pressure reheater is disposed in the central further divided passage. In another embodiment, the locations of the superheater and the high-pressure reheater are reversed.Type: GrantFiled: April 13, 1987Date of Patent: July 5, 1988Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Hisao Haneda, Mamoru Araoka, Toshihiro Kamata, Tetsuo Sada
