Abstract
A power system includes a device for extracting energy from a hot gas stream to power a driveshaft. An evaporative duplex counterheat exchanger is disposed in flow communication with the energy extracting device. The duplex exchanger includes a first heat exchanger having a first main flow channel, and a counterheat channel joined in flow communication therewith. A second heat exchanger includes a second main flow channel adjacent the counterheat channel. And, a evaporative fluid is injected into the counterheat channel to evaporatively cool the flow through both main flow channels.
Claims59
A power system comprising:
- a driveshaft;
- means for extracting energy from a hot gas stream to power said driveshaft;
- an evaporative duplex counterheat exchanger including a first heat exchanger having a first main flow channel and counterheat channel joined in flow communication therewith, a second heat exchanger having a second main flow channel adjacent said counterheat channel, and means for injecting an evaporative fluid into said counterheat channel;
- and
- said duplex exchanger being joined in flow communication with said energy extracting means.
A system according to claim I wherein:
- said first and second main flow channels are independent from each other and from said counterheat channels for maintaining dry flow channeled therethrough;
- and
- said counterheat channel is disposed between said first and second main flow channels for wetting flow discharged from said first main flow channel to evaporatively cool said first and second main flow channels.
