富氧燃烧技术

来源:科技管理部  发布时间:2013-02-12

      中国联合水泥集团有限公司、 通辽中联水泥有限公司予以合作开发形式开发水泥窑富氧燃烧技术。该项目以富氧燃烧技术为主要手段,在回转窑中使用25%~30%的富氧空气,提高燃料的燃烧效率,或者使用劣质煤替代优质煤,从而大大降低熟料的成本。利用富氧空气助燃,实现煤炭资源清洁利用和提高煤炭资源利用的附加值。

 主要技术指标:

      1.富氧空气量:回转窑富氧流量4500m3/h,预分解窑富氧流量大于4600m3/h;

      2.富氧空气体积浓度:回转窑富氧空气浓度24~25%,预分解窑富氧空气浓度23%;

      3.输出富氧空气温度:>30℃;

      4.分离后富氧空气压力:>5kPa;

      5.膜组件有效使用时间:>5年;

      6.空气过滤器级别:欧洲标准(CEN EN)H11级;

      7.供电电压:三相380V;

      8.富氧系统运转功率:不大于520Kw;(分离后的高压氮气,可供水泥窑清灰,将可替代原来空压机,替代功率约230kW,所以富氧系统实际消耗功率200多kW。)
