中国煤炭清洁燃烧技术路线图的初步探讨

Preliminary Discussion on the Technology Roadmap of Clean Coal Combustion in China

在防治污染的迫切要求下,中国必须加快发展煤炭清洁燃烧技术,但当前针对中国煤炭清洁燃烧技术路线图的研究还相对缺乏。本文对我国煤炭利用的结构特点、发展煤炭清洁燃烧技术的重要意义进行了概述,并重点围绕六类煤炭清洁燃烧技术发展的战略思路和目标、国内外技术现状、未来技术方向、重点领域和关键技术等问题进行了初步探讨。在此基础上,描绘了2050年前中国的煤炭清洁燃烧技术路线图,并给出了相关战略建议。结果表明,近期必须加快在中小型燃煤工业锅炉中应用一批新型循环流化床技术,在民用散烧煤领域推广一批优质型煤和先进炉具,切实减少分散式燃煤污染。从长远来看,政府应加强规划引领,切实提高煤炭用于清洁高效集中发电的比重,并持续研发一批面向未来的绿色煤电技术和系统。

As it is urgently required to prevent and control pollution,China must accelerate the development of clean coal combustion technologies.However,currently there lacks researches on the technology roadmap of clean coal combustion in China.This paper briefly introduces main features of the coal utilization structure in China,and also the significance in developing clean coal combustion technologies.Then,focusing on 6 types of clean coal combustion technologies,we discuss the strategic ideology and targets,status quo at home and abroad,future technical directions,major fields and key technologies.On this basis,we depict a technology roadmap for the clean coal combustion in China before 2050,and also provide relevant policy recommendations.Results indicate that in the near future,China must accelerate the application of new circulating fluidized bed(CFB)technologies in small and medium-sized coal-fired industrial boilers,and popularize a batch of high-quality briquettes and advanced stoves in the field of residential coal combustion,so as to reduce the dispersed coal-burning pollution.In the long run,the government must strengthen planning and guidance to increase the proportion of coal for clean and efficient centralized power generation,and continuously research and develop green coal power generation technologies and systems for the future.
