A new innovative cycle, the Kalina cycle, now appears poised for moving the power industry a giant step forward in its quest for higher efficiencies. A review of Kalina cycle Heat balances indicates a potential for significant gains in plant efficient compared to equivalent Rankine cycle plants. Efficiency gains of up to 50 percent may be realized for low heat energy sources such as geothermal brine at 300 to 400 F. Gains of up to 20 percent may be realized for higher temperature heat sources such as direct fired boilers and exhaust gases from a gas turbine, i.e. bottoming cycle of a combined cycle plant. This article is intended as a primer on the Kalina cycle. As such, this article focuses on two things--the basic thermo-physical properties of ammonia-water as a working fluid and the general application techniques used in the Kalina cycle arsenal of designs to exploit these properties for higher efficiencies.
