| | This article gives a brief description of the Model D3-1.7/0.5 experimental geother-mal steam turbine unit developed by Qiangdao Steam Turbine Works. Two units of this type have been in operation in Yangbajing experimental geothermal power station and the third one is now under installation. Design considerations for the thermody-namic system, plant layout, steam turbine proper, the oil system for governing and safety control, butterfly valves and some major auxiliary equipment are given. The article conclu... | | 本文简要地介绍了由青岛汽轮机厂研制的D3—1.7/0.5型地热发电用试验汽轮机组。该机组已有两台在西藏自治区羊八井地热试验电站中运行,第三台也正在安装之中。文中叙述了该机组的热力系统、电站布置、汽轮机本体、调节保安油路系统、蝶阀以及几种主要辅助设备的设计情况。最后,对该机组运行情况及所获得的经济效果也作了简要的介绍。 | | 文摘来源 | | A survey was made in the article on the development of geothermal power generation in China and some other countries. With the limited information available as well aS the space of the article, a survey covering every detail would be impossible. However, a general picture of the trend and development in this field will still be of some value to the readers. | | 本文简要地介绍了我国及国外一些主要国家的地热发电发展的概况。由于资料及篇幅所限,未能对所有的地热发电情况给予全面的介绍,但可有助于读者了解现代地热发电发展的趋势。 | | 文摘来源 | | Article gives an overall introduction of the operation of D3-1.7/0.5 type geothermal turbine. The introduction covers the well tube deposition condition, steam and water separate supply system, steam and water system and its associated butterfly .valves, urbine flow path, control and safety system as well as turbine auxiliaries. The turbine has proved to be quite satisfactory after the comparisons made with other geothermal stations outside China. | | 西藏羊八井地热电站的第一座电站总装机容量己达1万千瓦,其中有青岛汽轮机厂研制的D3-1.7/0.5型两次进汽混压式地热汽轮机组3台.本文对该机组的运行概况作了报道,文中报道了地热发电运行中特有的防垢、除垢、材料腐蚀、使用防蚀及防垢涂料的效果、地热汽轮机组的运行情况以及地热发电所取得的效果.最后,还以羊八井地热电站与国外一些地热电站进行比较,说明羊八井地热电站所取得的效果是良好的. | | 文摘来源 | |   | | << 更多相关文摘 |
