煤的清洁利用技术的现状与发展

The present and future of clean coal technology

  • 摘要: 文章针对中国一次能源以煤为主的特点,深入分析了几种主要的煤的洁净利用技术的现状及存在的主要问题和发展趋势,其中包括大容量、高参数的超(超)临界燃煤发电技术、燃煤烟气净化技术、循环流化床燃烧技术(CFBC)、整体煤气化联合循环技术(IGCC)和煤的洗选技术.在此基础上,给出了中国煤的清洁利用方式的建议:近期仍以超(超)临界燃煤发电机组+燃煤烟气净化技术和循环流化床燃烧技术为主;整体燃气化联合循环技术、富氧燃烧技术(特别是加压富氧燃烧技术)以及二氧化碳的捕集和封存技术(CCS),具有广阔应用前景,值得长期大力发展.

     

    Abstract: Based on the primary energy characteristics of China, the current status and future development of clean coal technologies, including large-scale ultra-super-critical (USC) power generators, flue gas cleaning, circulating fluidized-bed combustion (CFBC), integrated gasification combined cycle (IGCC) technology,and coal washing are analyzed in details. It can be concluded that, in the short term, USC generation with flue gas cleaning and CFBC will be the two major clean coal technologies in China. However, IGCC, oxy-fuel combustion (especially pressurized oxy-fuel combustion), and CO2 capture and storage are of great potential and are worth developing in the long term.
