火力发电产业发展与前沿技术路线

Industry Development and Frontier Technology Roadmap of Thermal Power Generation

"十三五"期间火力发电行业经历着转型升级,研究提出火力发电的技术路线,目标是为火力发电行业的研究发展战略提供参考。研究介绍了火力发电的产业概况和主要指标,总结了燃煤发电、燃气发电和余热发电等发电形式的前沿技术。研究讨论了各项前沿技术的效率与规模等关键技术指标,并预测了单位电量成本等关键经济指标的趋势。研究明确了700℃超超临界燃煤发电、超临界二氧化碳布雷顿循环、煤气化联合循环等前沿技术应当作为未来长期重点突破和完善的关键技术。研究提出了集中式和分布式火力发电的四条前沿技术路线,并对各条技术路线的未来长期发展前景进行了对比分析。

During the 13th Five-Year Plan period, thermal power generation industry is experiencing the transformation and upgrading. Technical routes of thermal power generation were proposed, aiming to provide reference for research and development strategy of thermal power generation industry. Industry overview and main indictors of thermal power generation were introduced. The frontier techniques of coal-fired, gas and waste heat power generation forms were concluded. Key technical indexes including efficiency and scale of frontier techniques were discussed, meanwhile tendency forecasts of key economic indicators such as levelized costs of electricity were given. The study identified the frontier techniques including 700℃ ultra-supercritical coal-fired power generation, supercfitical CO2 Brayton cycle and integrated gasification combined cycle should be the key techniques that need breakthroughs and improvements emphatically in the long-term future. Four frontier technology roadmaps were came up for both centralized and distributed thermal power generation, comparisons and analysis of long-term future development prospects of these technology roadmaps were also conducted.
