Patent number: 7654396Abstract: A classifier capable of stably providing particles by further reducing the mixing ratio of coarse particles including a rotating fin (21) classifying solid particles by a centrifugal force, a cylindrical downward flow forming member (13) installed on the outer peripheral side of the rotating fin (21), a recovery cone (11) disposed under the rotating fin (21) and the downward flow forming member (13), and a housing (41). A contraction flow area (16) is formed between the housing (41) and the recovery cone (11), and a two-phase flow (52) formed of the mixture of the solid particles and gases blown up through the contraction flow area (16) is collided with the downward flow forming member (13) on the upper side of the housing (41) to form it in a downward flow. Then, that flow is led to the rotating fin side, classified into the fine particles and the coarse particles, and the fine particles are carried together with an airstream, passed through the rotating fin (21), and removed.Type: GrantFiled: May 12, 2005Date of Patent: February 2, 2010Assignee: Babcock-Hitachi Kabushiki KaishaInventors: Yutaka Takeno, Hiroaki Kanemoto, Teruaki Tatsuma, Takashi Harada, Taketoshi Tanabe

Patent number: 6976440Abstract: A fuel supply duct, which supplies a mixed fluid of a solid fuel and carrier gas to one or more burners provided on the walls of a furnace, is provided with a branching part, and each of a plurality of branch ducts, which branch out from the branching part, is connected to a corresponding burner. Also a damper, with which the tilt angle with respect to the direction of flow of the mixed fluid can be changed, is positioned in the fuel supply duct at the upstream side of the branching part so that a mutual difference will arise in the solid fuel concentrations of the mixed fluid supplied to the respective branch ducts. A fuel distributor for fuel supply duct is thus arranged. The tilt angle of the above-mentioned damper is adjusted to increase the concentration of solid fuel in the mixed fluid supplied to a specific burner. At a burner to which the high solid fuel concentration is supplied, stability of ignition and stable combustion of the ignited flame can be obtained during low load operation.Type: GrantFiled: December 3, 2001Date of Patent: December 20, 2005Assignee: Babcock-Hitachi Kabushiki KaishaInventors: Yoshinori Ohtani, Hidehisa Yoshizako, Hiroaki Kanemoto, Yutaka Takeno, Yoshio Shimogori, Toshikazu Tsumura, Yoshitaka Takahashi
