Turbine with heating and cooling

Abstract

A method and apparatus for generating power by passing a fluid from a higher energy level to a lower energy level by compressing said fluid first in a continuous flow centrifuge rotor and then reducing the pressure of said fluid in an inward flow reaction turbine section. The fluid enters the first rotor at center and leaves the second rotor at center, and vanes are provided within both rotors to assure that said fluid will rotate with said rotors. Nozzles are provided near the periphery of the first rotor to increase the absolute tangential velocity of the fluid leaving said first rotor; the tangential velocity of second rotor near rotor tip is greater than said first rotor tangential tip velocity. The said fluid is contained within said rotors, and passes from said second rotor to said first rotor near rotor center. Heat is being added to said fluid near the first rotor periphery, and heat is being removed from said fluid near the center of said first rotor; both heat addition and heat removal are mainly conducted during said compression of said fluid. Said fluid is normally a gas, and said heat addition and removal are usually conducted by using a second fluid which may be a gas or a liquid, and a third fluid which may be also a gas or a liquid.

Description

Claims

1. An improvement in a turbine for generating power, said turbine comprising:

a. a casing for supporting rotor shafts;

b. shafts journalled in bearings in said casing for rotation;

c. a rotating first rotor mounted on a shaft so as to rotate therewith, said first rotor being of circular configuration, and having an entry port for a first fluid near the center of said first rotor and having a radially outwardly extending passageway for said first fluid for effecting acceleration and centrifugal compression of said first fluid; said radially extending passageway being provided with a heat exchanger for adding heat to said first fluid during and after compression; said radially extending passageway being provided with a set of nozzles at its downstream end for passing said first fluid with said nozzles oriented to discharge said first fluid in forwardly tangential direction;

d. a rotating second rotor mounted on a shaft so as to rotate therewith; said second rotor having an entry for said first fluid adjacent to said first rotor nozzles for receiving said first fluid, with inward extending first fluid passageway for expansion of said first fluid and for receiving by said rotor the work associated with deceleration of said first fluid; said second rotor having an exit port for said first fluid near the center of said rotor for passing said first fluid into said first rotor;

e. a heat removal heat exchanger being provided to cool said first fluid before and during early part of compression, said heat removal heat exchanger being within said first rotor and being in heat exchange relationship with said first fluid.
