简介:摘要我公司6、7号机组脱硝系统采用低氮燃烧器+SCR法以减少NOx生成。2014~2016年6号机组脱硝系统投运期间,由于机组启动次数少及经验不足,在机组启动过程中基本不能按期投入脱硝系统,延长了达标排放时间,影响同步投运率,且增加了环保排污费用。随着7号机组投运后,机组启动次数增加很多,每次都有不同原因影响脱硝系统的及时投入,环保排污费用明显增加,为公司带来巨大经济损失。为了满足环保新标准,我们通过全面分析原因,采取优化运行方式后,从2016年5月开始每次机组启动,SCR入口烟温超过295℃都顺利的投入了脱硝系统,提高了脱硝同步投运率,且环保排污费用明显减少了。

简介:摘要针对目前单机容量的增长和永磁同步电机应用日益广泛,且在电机实际运行过程中不可避免的会偏离稳定运行而进入混沌状态的情况,本文在原有永磁同步电机的混沌模型的基础上提出了其简化模型,将非自治方程转化为自治方程,大大简化了运算和分析。
