Thermodynamic Kalina Cycle® Flow Diagram

The Kalina Cycle® is recognised as one of the most thermodynamically efficient power cycle technologies in the world. This system uses a mixture of ammonia and water as a working fluid, rather than a pure substance such as water, which is commonly used in the Rankine Cycle.

The five steps in the thermodynamic cycle include:

1. Compression in the pump
2. Heat addition in the boiler
3. Expansion in the turbine
4. Recuperation in the recuperators
5. Heat rejection in a condenser

The added degree of freedom of a variable mixture working fluid, which can be heated at one composition and condensed at a different composition, leads to the DCSS which serves the functions of distillation, recuperation and heat rejection in the condenser.
