摘　　要：低压加热器是从汽轮机的中后级抽出的部分蒸汽来加热凝结水以提高汽轮机效率的给水加热设备。武钢鼓风车间通过对原有的低压加热器进行改造并投运,提高凝结水回水温度及冷凝器真空度,减少汽耗量,获得可观的经济效益。Low pressure heater is a heating-water apparatus which draws out part of steam coming from intermediate-rear stage of turbine to heat the condensed water in order to increase the efficiency of turbine. WISCO blower workshop reconstructed its old low pressure heater and put it into production in order to improve the condition of returning-water temperature as well as its condensing vaccum and reduce consumption amount of steam. As the results considerable economic benefits have been achieved.

关 键 词：低压加热器 改造 凝结水 真空度
