Continuous operation of a geothermal power plant basically relies on the sustainable geothermal source and skilled operation of the resource and power plant. Major problems encountered are mostly related to the chemistry of geothermal water. Aluto Langano pilot plant has encountered many problems over the years of service. This paper discusses some of the plant problems and, in order to gain experience and increase understanding of the operation and maintenance of the plant, gives a review of actions taken to overcome similar problems in other plants. An energy analysis of the plant is made on EES to analyze how the plant reacts to different operating conditions and to optimize operation. As the geothermal field of Aluto Langano is a high-temperature field, silica formation with current flow is also analyzed. |
