Geothermal Energy Converter (USA)
The ORMAT® ENERGY CONVERTER (OEC) is a power generation unit, which converts low, medium and high temperature heat into electrical energy. The OECs are designed for the specific conditions of a wide variety of heat sources. Its main components include a vaporizer/preheater, turbogenerator, air-cooled or water-cooled condenser, feed pump and controls. It is designed for outdoor installations. The OEC is a field-proven, mature commercial product used in 71 countries worldwide. Ormat has successfully manufactured and supplied more than 800 MW of geothermal power plants, based on its proprietary technology, logging millions of hours of operating experience. The OEC enables geothermal developers to efficiently and economically use the full range of naturally occurring geothermal resources found throughout the world - from low temperature geothermal water to high-pressure steam. The OECs can accommodate a wide range of geothermal fluid temperatures and chemistries: - Steam pressure: from 1.5 bar (21.8 psig) up to 25.0 bar(362 psig) - Brine temperature: from 100'C to 224'C - Silica content: up to 1.95 silica index - NCG content: up to 15% Available in sizes and configurations cost-effectively matched to specific resource and project requirement, rather than imposing standardized plant sizes Capacity range: from 250 kW to 130 MW For more information, contact: Ormat Technologies, Inc. 6225 Neil Road, Suite 300 Reno, Nevada 89511-1136 Tel: (775) 356-9029 Fax: (775) 356-9039 E mail: [email protected]

Advantages: 100% reinjection Enabling 100% reinjection of the geothermal fluid (except NCG in some cases); maximizing reinjection will serve to maintain reservoir pressure and sustain the life of the aquifer. Air-Condensers for Sustainability and Environmental Benefits In addition of enabling 100% reinjection, air-cooled condensers minimize the environmentally negative impact of emissions and acid rain from cooling towers and eliminate the use of chemicals for water treatment Low visual profile High Availability Ormat binary cycle plants have demonstrated average plant availability of over 97%, with typical individual OECs demonstrating generally over 95% availability Modularity The modular approach is leading to flexibility, high average plant availability, faster delivery time and the capability of incremental development of projects Incremental Development Use of the modular concept and cost-effective plants at modest capacities makes it feasible to develop projects in an incremental manner, which is a more economically viable and less risky approach Repowering Existing Plants The use of OECs for repowering existing power plants enables to produce more power without additional resources by: - Use of excess inlet steam pressure through unique "topping" turbines - Utilize unused heat of brine discharged from a separator Small/Medium Scale Projects OEC technology is also commercially applicable for small-scale projects where the resources are limited, the power demand small and/or where the conventional technology is not economically viable
