| Abstract | In the planning stage of a geothermal power plant with high non-condensable gas (herein called NCG) content, the total system engineering, including selection of NCG removal and of condenser vacuum is very important. This report discusses the design of a geothermal power plant with a large quantity of NCG content in the steam. The captioned power plant is a hot water dominated geothermal power plant and the hot water contains a large quantity of NCG. The system and equipment of the plant are designed under consideration of their characteristics and also for the preservation of the scenery and the environment. Therefore, This plant is to provide a large sized gas compressor coupled directly with the main steam turbine shaft as the NCG removal system and condenser pressure selected has to be relatively high to reduce auxiliary power. The design offers a compact and efficient power plant. |
