Abstract

Abstract:

Thermal power generation is the largest source of electricity and CO₂ emission in China. CO₂ emission reduction in thermal power generation industry is an important guarantee for the smooth realization of the goal of “carbon peaking and carbon neutralization”. In order to explore the development path of China’s thermal power generation technology under the background of “carbon peaking and carbon neutralization”, combined with the analysis of development process of China’s thermal power generation industry and the prospect of China’s medium and long-term power consumption structure, we predicted that China’s thermal power generation technology will change from focusing on high parameter and high efficiency to peak shaving flexibility. Through the discussion and study of the ultra-high parameter thermal power generation technology, flexible peak shaving technology, IGCC/IGFC technology, it is found that the development of ultra-high parameter thermal power generation technology is limited by high temperature resistant materials. Moreover, the flexible transformation can effectively extend the life cycle of thermal power generation technology. IGCC/IGFC power generation technology was believed to be a clean-coal power generation technology with high efficiency and flexibility, and the application scenario of coal-gas (oil)-electricity integrated energy base was further proposed. Looking forward to 2060, it is suggested to strengthen the study of coal gasification/purification technology, fuel cell power generation technology and IGFC system integrated control technology, to help China achieve carbon neutralization

Key words: thermal power generation, carbon neutralization, advanced ultra-supercritical coal-fired unit, integrated gasification combined cycle, integrated gasification fuel cell combined cycle, clean-coal
