Title: Control method and device for pressurized fluidized bed boiler-compound power generation facility
Inventor: JOGE TOSHIO
IPC: F22D5/26
Filed: 1993-03-05
Abstract: PURPOSE:To realize the operation suitable for cooling a boiler at the time when the fuel supply to the pressurized fluidized bed boiler is stopped by determining the amount of feed water in response to the retained heat of a furnace- fluidized bed, and controlling the amount of other processes of the pressurized fluidized bed boiler in accordance with the amount of the feed water. CONSTITUTION:In a pressurized fluidized bed boiler, at least one part of a heat transfer pipe 3 in which feed water flows, is in contact with a flowing material to perform heat-exchange. A steam turbine 11 and generator 12 are driven by the steam obtained from the heat transfer pipe 3. A gas turbine 8 supplies high-pressure air to the pressurized fluidized bed boiler. When the cause of boiler-trip is judged and the steam turbine 11 is found to be tripped, the main steam pressure is controlled by a turbine-bypass valve 17. When a boiler mechanical stoker is out of order, the main steam pressure is controlled by a steam turbine governor 10, because the steam turbine 11 and the steam turbine-generator 12 are continuing the operation. Thus, at the time of boiler- trip, the boiler is shifted to a usual boiler stopped state to reduce thermal stress.

Title: Inductance parts
Inventor: ARAI YASUO
IPC: H01F17/04
Filed: 1984-03-09
Abstract: PURPOSE:To obtain high performance, by using an approximately rod shaped core, in which thin bands of amorphous magnetic bodies are laminated or wound and a space factor is made high, applying conducting windings on the core, thereby increasing saturated magnetic flux, reducing loss, and making the magnetostriction sufficiently small depending on uses. CONSTITUTION:Conducting windings 2a and 2b are wound around amorphous magnetic bodies 1a and 1b in inductance parts. In these inductance parts, the characteristic of low core loss at a high frequency as well as the characteristic of high-saturation magnetic-flux density of amorphous material are utilized. Even though a large current is made to flow, the parts are not readily saturated. The parts yield less heat at high frequencies. These are major characteristics. The rod shaped magnetic bodies can be readily manufactured from the thin- band shaped amorphous material. It is recommended that the absolute value of the magnetostriction as the characteristic of the amorphous material is as small as possible. The value in the range from -1.2X10<-6> to +1.2X10<-6> can be used in the actual parts.
