摘要(Abstract):
结合中东地区某联合循环项目实例,说明了余热锅炉补燃系统的应用和极端气候下主、辅机冷却系统的选型。分析表明,受资源禀赋影响,补燃系统可为该地区发电厂带来额外电费收益;受环境条件影响,主、辅机空冷系统在该地区应用广泛。同时,基于GT pro软件对中东地区常出现的联合循环主机岛"三拖二"配置进行了性能计算和对比,初步探讨了"三拖二"配置的优劣。
Based on a combined cycle project in the Middle East, the application of the HRSG supplementary firing system and the selection of the main and auxiliary cooling system under extreme climates are introduced. The analysis shows that the supplementary firing system can bring additional electricity revenue for power plants in the region due to resource endowments, and the air-cooling system is widely used in the region due to environmental conditions. Meanwhile, performance calculation and comparison on the "Three-onTwo" configuration of the combined-cycle master island in Middle East were carried out by GT pro software.The advantages and disadvantages of the "Three-on-Two" configuration were discussed.
