Patent number: 9334800Abstract: To provide a method of controlling a turbine equipment and a turbine equipment capable of carrying out a starting operation of controlling a load applied to a speed reducing portion while complying with a restriction imposed on an apparatus provided at a turbine equipment. The invention is characterized in including a speed accelerating step (S1) of increasing a revolution number by driving to rotate a compressing portion and a turbine portion by a motor by way of a speed reducing portion, a load detecting step (S2) of detecting a load applied to the speed reducing portion by a load detecting portion, and a bypass flow rate controlling step (S3) of increasing a flow rate of a working fluid bypassed from a delivery side to a suction side of the compressing portion when an absolute value of the detected load is equal to or smaller than an absolute value of a predetermined value and reducing the flow rate of the bypassed working fluid when equal to or larger than the absolute value of the predetermined value.Type: GrantFiled: March 27, 2009Date of Patent: May 10, 2016Assignees: MITSUBISHI HEAVY INDUSTRIES, LTD., PEBBLE BED MODULAR REACTOR (PTY) LIMITEDInventors: Hitoi Ono, Takashi Sonoda, Naoto Tochitani, Makoto Kato, Masahide Umaya, Fuminori Fujii

Patent number: 5246338Abstract: In a mixed gas turbine, wherein excessive steam in a plant is mixed with exhaust gas of a high-pressure turbine and then introduced to a low-pressure turbine, the present invention makes improvements such that even when a flow rate of the main flow in the high-pressure turbine is small, an efficiency may not be lowered. A final stage of a high-pressure turbine and a mixed-gas pressure adjusting stage are arrayed in opposition with an exhaust gas chamber of a high-pressure turbine casing placed therebetween, also a flow passage guide plate is provided within the exhaust gas chamber to rectify the flows of the exhaust gas in the final stage and the mixed-gas in the pressure adjusting stage and lead them to an exhaust gas port and a low-pressure turbine communication pipe by mixing their pressures.Type: GrantFiled: May 27, 1992Date of Patent: September 21, 1993Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Kiyoshi Takayanagi, Masahide Umaya
