摘　　要：针对褐煤机组特点,以北方采暖供热机组为例,建议设置烟气余热换热器,回收烟气的余热。方案在采暖期及非采暖期利用烟气尾部余热分别加热热网水或凝结水,降低全厂热耗,提高机组效率,并且节省全厂用水。经计算,经济效益十分明显,不到2年即可回收初始投资,并有显著的节能减排效果。According to the actual characteristics of lignite,suggestions that flue gas heat recovery technology should be adopted especially for heat supply units in North China are proposed in the paper.In order to reduce the consumption of fuel as well as water,the exhaust gas is applied to heat the network steam and the condensation water,and significant economic benefits have already been achieved in the past two years.
