摘　　要：针对莱钢130 t/h燃气锅炉排烟温度高,热量损失大,增加了尾总烟道烟气换热设备,提高凝结水给水温度,减少除氧用蒸汽量,达到了节能降耗的目的。To solve the problem of excessive flue gas temperature and high heat loss ofthe 130 t/h gas boiler at Laiwu Steel, a rear flue gas heat exchanger was added, which hasincreased the condensate water temperature, reduced the amount of steam consumption by deoxidization and achieved the objective of energy saving.

关 键 词：排烟温度 低温换热器 烟气余热
