摘　　要：近年来我国水泥产量逐年增高,水泥生产过程中的NOx排放量也越来越大,因此,控制水泥行业NOx的排放压力巨大.详细介绍了富氧燃烧技术应用于水泥行业进行脱硝的机理、研究现状及存在问题,并对富氧燃烧技术应用于水泥行业进行脱硝的可行性进行分析,得出此技术对于减少水泥行业中的NOx排放具有很大潜力.As the amount of cement production increase every year in China, the total amount of NOx emissions from cement production process is also growing heavily. Therefore, the control over NOx emissions becomes an urgent task in cement industry. In this paper, the feasibility of oxy-fuel technology used for cement production process to control NOx emissions is analyzed. The mechanism of denitration, the state-of-the-art research and challenges of oxy-fuel technology are discussed. The paper concludes that there is a great potential for reducing the cement industry NOx emissions by using oxy-fuel technology.
