Abstract: In July 2000, Kalina cycle is first time used in Husavik, Iceland and is considered to be one of the most promising ways for utilizing the low-temperature heat sources. By using the software of EES, a calculating program is compiled to simulate the cycle process and the results have fitted with the actual operating parameters quite well. On this basis, the influence factors, such as turbine inlet pressure and mass fraction of ammonia which associated with the cycle efficiency are analyzed. In addition, the safe operating range of turbine is calculated and the exergy loss is sized up.
