我国是世界最大的煤炭消费国, 火电消费占了全国煤炭消费总量的53%。为了完成节能减排的目标, 大幅度提高火电行业的能效水平乃不二选择。基于研发中的700℃高效超临界计划尚存在技术和造价瓶颈的现实, 应探索在现有技术的条件下的低碳煤电之路。事实上, 现有火电的技术体系中, 设备、设计、调试、运行及控制方式等, 仍存在着很大的节能空间, 上海外高桥第三发电厂1 GW超超临界机组, 在建设期及投产后, 通过全面的优化和持续的创新, 使目前的机组效率远远超过了设计值, 创世界之最。另外, 采用“一种新型的汽轮发电机”专利技术, 结合节能创新, 能将机组的净效率进一步提升至48.5%以上, 远超一次再热700℃高效超临界机组的期望值, 并能一举打开700℃计划的材料和造价瓶颈, 开辟更高效机组的发展新路。

As the largest coal consuming country, China takes about 53% of coal resources for thermal-power. To accomplish the goal of energy conservation and emission reduction, the energy efficiency of whole thermal-power industry should be greatly enhanced. For there still exists technical and cost bottleneck during the research of high-efficiency supercritical power-generation under 700℃, the study of existing equipments, design and debug process, and running management behaves more practical. After full-scale optimization and continuous innovation, the 1 GW Ultra-Supercritical-Power-Generators in The Shanghai WaiGaoQiao NO.3 Power Plant behave far more efficien than designed and set the top of the world. The net efficiency could be further raised up to 48.5% by adopting a new patented steam turbine technology. This result is far beyond the expectation and will lead to break the bottleneck and find a new direction for the development of high-efficiency generating-unit.
