摘要
我国作为世界最大的煤炭消费国,火电消费占其53%。为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℃高效超临界计划和IGCC技术尚存在技术和造价等瓶颈的现实,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1000MW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,目前的机组效率远远超过了设计值,创世界之最。另外,本文论述了采用"一种新型的汽轮发电机"专利技术,结合其它节能创新项目,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。
china becomes the world's largest coal-consuming country and thermal power generation is about 53% of total consumption. To complete energy-saving and emission-reducing targets, it's significant to improve energy efficiency of thermal power generation industry. Based on reality of both 700℃ efficient super-critical R&D programs and IGCC technology's technical and cost bottleneck, we should keep exploring existing low-carbon coal technology. In fact, under the current system of thermal power generation technology condition, there are a lot of energy-saving areas such as equipments, design, commissioning, operation and control methods. Shanghai waigaoqiao power plant III has 1000MW super critical units. After construction period and operation, it went through a comprehensive optimization and continuous innovation, it's efficiency is far more than the design value as updating world's record. On the other hand, this article discusses application of a brand new type of turbine-generator patent combined with other energy-saving innovation projects. The net efficiency of the unit can be further improved to 48.5%, which is far more than reheat 700℃ efficient super-critical unit's expectations. It also overcomes 700% efficient super-critical R&D programs" materials and cost bottleneck and opens up new road to more efficient unit development.
