Kalina CyclesLow-Temperature Processes
The Kalina cycle, developed by Dr. Alexander Kalina, is a thermodynamic process for converting thermal energy into usable mechanical power. It uses a solution of two fluids with different boiling points (ammonia and water) for its working fluid. Since the solution boils over a range of temperatures as in distillation, more of the heat can be extracted from the source than with a pure working fluid. The same applies on the exhaust (condensing) end. This provides efficiency comparable to a Combined cycle, with less complexity. Water and ammonia is the most widely used combination, but other combinations are feasible.
Because of its ability to take full advantage of the temperature difference between the particular heat source and heat sink available, Kalina cycles can find applications in industrial heat recovery, geothermal energy, concentrating solar power (CSP), and use of waste heat from power plants (bottoming cycles).
