摘要
在不提高当前超超临界机组参数的情形下,采用二次再热技术是提高机组效率、减少二氧化碳和氮氧化物等燃烧污染物排放的重要途径之一。对国外超超临界二次再热技术的发展状况进行了综述,详细介绍了我国正在建设的二次再热机组的基本情况,探讨了二次再热关键技术难点及研究热点,旨在推动我国二次再热技术的研究工作。
On the basis of keeping the current ultra-supercritical steam parameter of the unit with single reheat cycle constant, applying double reheat cycle can improve the unit efficiency as well as reduce the CO2 and NOx emission. The development of ultra-supercritical unit with double reheat abroad is summarized and current situation in China is introduced in detail. Key technology and research focus are discussed, aiming at promoting the research work of double reheat cycle in China.
