Abstract: The mechanisms and influencing factors of elemental sulfur formation have been elaborated and analyzed. The prediction methods for elemental sulfur formation have been presented. Based on the geothermal steam parameters and steam turbine operating data from a typical wellhead power plant located at Olkaria in Kenya, the amount of elemental sulfur formation in mixing condensers has been calculated. Suggestions on the prohibition of elemental sulfur deposition inside mixing condensers were put forward. This paper provides a scientific guidance for the optimum design and efficient operation of geothermal power plants.
