Patent Searching and Data

Document Type and Number:
Japanese Patent JP2007092584
Kind Code:

To provide a thermal power generation system wherein a contact bearing with a minimum contact area is used, a turbine can be rotated for a long period of time without restriction of kinds of working medium, rotation can be smoothly started, and a problem of deterioration in whole efficiency caused by a troublesome control or electric consumption unlike electromagnetic support is eliminated, so that a cost is reduced and generating efficiency is good.

By a collector 1 absorbing thermal energy, the working medium 3 is heated directly or indirectly, vapor of the working medium 3 is jetted from a nozzle 8, and the turbine 5 is rotary driven by high-pressure vapor from the nozzle 8. The rotation of the turbine 5 rotates a generator rotor 6A in a generator 6, and a generator starter part 6B disposed to face the generator rotor 6A generates electric power. A main shaft 7 connecting the turbine 5 with the generator rotor 6A is installed in a vertical direction, and a lower end of a main shaft 7 is supported by a pivot part 11, and an upper part of the main shaft 7 is supported by repulsion of permanent magnets 12, 13.
