The Kalina Cycle® is the most significant improvement in the steam power cycle since the advent of the Rankine Cycle in the mid 1800s. In a typical Rankine Cycle power plant, a pure working fluid, water or in the case of Organic Rankine, low molecular weight organic compounds, is heated in a boiler and converted into high-pressure, high temperature vapour which is then expanded through a turbine to generate electricity in a closed loop system.
The Kalina Cycle® utilises an ammonia-water mixture as a working fluid to improve system thermodynamic efficiency and provide more flexibility in various operating conditions. The Kalina Cycle® can improve power plant efficiency by 10% to 50% over the Rankine Cycle depending on the application. As plant operating temperatures are lowered, the relative gain of the Kalina Cycle® increases in comparison with the Rankine Cycle.
