| 22 | Apparatus for producing power using concentrated brine | US894902 | 1986-08-08 | US4704993A | 1987-11-10 | Gad Assaf |
| A power plant includes a source of water, a heat exchanger having an evaporator side maintained below atmospheric pressure for converting the water to steam, and a turbine responsive to said steam for producing work and heat depleted steam. The heat exchanger also has a condenser side for receiving and condensing the heat depleted steam. The evaporator side of the heat exchanger is separated by a barrier from the condenser side. Concentrated brine from a source thereof is caused to fall in a film on the condenser side of the barrier, and water from the water source is caused to fall in a film on the evaporator side of the barrier. The heat of dilution of the film of concentrated brine, as it is directly contacted by the heat depleted steam in the condenser side of the heat exchanger, is transferred through the barrier from the condenser side to the evaporator side raising the temperature of the film of water on the evaporator side which evaporates in the reduced pressure in the evaporator. The cooled and diluted brine withdrawn from the condenser is reconcentrated in a constant enthalpy brine evaporator. | ||||||
| 23 | Closed cycle rotary engine system | US3744245D | 1971-06-21 | US3744245A | 1973-07-10 | KELLY D |
| The closed cycle rotary engine system consists of a rotary expander stage and rotary pump stage, which are driven together at a 1 to 1.+ ratio. The fluid/vapor closed loop is formed to enter and leave the two rotary stages tangentially so that a minimum number of simplified rotary components are required. Multiple boiler coils are located above and around the two rotary stages to heat an organic fluid working medium which expands in a vapor state to drive the expander stage rotor. Multiple condenser coils are located below and in front of the two rotary stages which cools the vapor to a liquid state which is then drawn into the rotary pump stage for further cooling and transfer. Supplementary heating and cooling techniques are adopted to enable a reduction in the total size and volume of the rotary engine system.
