| Abstract | Many engineering problems have been encountered during the detailed design stages of the Heber Geothermal Binary Plant. This paper highlights some of these design considerations related to the brine hydrocarbon heat exchanger warm up scheme, sizing o the turbine bypass system, and selection of the brine return pumps. In the Heber Power Plant, warm up of the brine/hydrocarbon heat exchangers is accomplished by gradually introducing a varying blended mixture of hot brine from the production wells and cooled, recycled brine through the heat exchangers. Also during the warm up mode, the hydrocarbon working fluid is gradually warmed up through a separate warm up circulation loop. A turbine bypass based on 20% of the turbine rated flow is also provided to control turbine inlet pressure during normal operation. |
