• Ammonia-water mixture
• Computing program
• Cycle efficiency
• Geothermal power generation
• Kalina cycle
• Large heat exchanger
• Operating parameters
• Turbine inlet pressure

Based on the principle of Kalina cycle system, a computing program simulating the cycle process was compiled by EES software, and the results have a good agreement with the actual operating parameters. The influence factors such as condensate temperature, turbine inlet pressure, ammonia mass friction, etc were analyzed using the software. The results showed that the cycle efficiency increases with the turbine inlet pressure at first, and then decrease, which indicates that there exists a peak value, and the cycle efficiency increases with the increasing of mass fraction of ammonia, however, excessively high mass fraction will results in large heat exchanger area which decline the economy. In addition, the safe operation of turbine was analyzed.
