浅谈国外煤粉富氧燃烧技术发展

Brief Discussion on Technical Development of Pulverized Coal Oxyfuel Combustion Abroad

富氧燃烧技术作为温室气体减排技术的一个重要分支,在近年得到了迅速发展。对国外燃煤电站富氧燃烧技术的研究进展进行了综述。介绍了煤粉富氧燃烧技术从实验室研究到中等规模试验研究的发展历程,重点分析了4个正在进行的示范项目的研究情况,指出目前煤粉富氧燃烧技术研究取得的成果以及研究尚存在一些问题和不足,为我国的煤粉富氧燃烧技术研究和应用提供参考。

As an important branch of greenhouse gas reduction technologies,oxyfuel combustion develops rapidly in recent years. In this paper,research development of pulverized coal oxyfuel combustion abroad is reviewed. Develop- ment process of pulverized coal oxyfuel combustion,from lab-scale study to small scale experimental research,is in- troduced. Through analysis of the research on four ongoing demonstration projects, some achievements are acquired ; on the other hand,there are still some problems. It can provide reference for the research and application of pulver- ized coal oxyfuel combustion in China.
