20090241545 | RADIAL COUNTERFLOW STEAM STRIPPER - Turbine exhaust steam, axially fed between counter-rotating radial flow disk turbines, separates into: (1) a radially inward flow of low enthalpy dry steam, and (2) a radially outward flow of high enthalpy steam, noncondensibles, and condensate. The radially inward flow goes to a conventional condenser. The radially outward flow loses enthalpy turning the disk turbines as it passes in the boundary layers against the disks, thus becoming low enthalpy dry steam, and the counter-rotation of the disks by impinging mass flow of condensate, high enthalpy steam, and noncondensibles sustains a cascade of dynamic vortex tubes in the shear layer between the boundary layers. The low enthalpy dry steam resulting from work being done flows into the condenser through the vortex cores of fractal turbulence. Condensate exits the periphery of the workspace, ready to be pumped back into the Rankine cycle. More condensate is recovered from the low enthalpy vapor in the condenser. Heat rejection from the cooling water circuit is easier because a significant mass fraction does not enter the condenser. Dynamic evaporative cooling of cooling water, uses fractal turbulence between counter-rotating centrifugal impellers, fed at their common axis of rotation with cooling water. Chilled water flows radially outward to recirculation, and hot water and vapor flows radially inward to the impeller axis of rotation. Vapor is stripped through the vortex cores of fractal turbulence into a condenser where it condenses as distilled water. Ultimate heat rejection is into the environment without discharge of vapor. | 2009-10-01 |
