The present invention relates to a device to reduce the corrosion of a heat exchanger for power generation. The device includes: a measurer measuring the diameter of a boiler tube, installed in a boiler, in real time; a corrosion reducing agent sprayer installed in the boiler to inject a corrosion reducing agent into the boiler; and a control part controlling the corrosion reducing agent sprayer to inject the corrosion reducing agent in real time by comparing and determining results of measuring a corrosion state in accordance with a change of the diameter of the boiler tube, measured by the measurer. As such, the present invention is capable of measuring the diameter of the boiler tube in real time and injecting different amounts of the corrosion reducing agent depending on variations of the corrosion of the tube, thereby more efficiently reducing the corrosion of the boiler tube. 발전용 열교환기의 부식 저감장치에 관한 것으로, 보일러 내부에 설치된 보일러 튜브의 직경을 실시간으로 측정하는 측정기; 상기 보일러 내부에 부식 저감물질이 투입되도록 상기 보일러에 설치되는 부식저감물질 분사기; 상기 측정기에서 측정된 상기 보일러 튜브의 직경 변화에 따른 부식 상태를 측정한 결과를 비교·판단하여 부식 저감물질이 실시간으로 투입되도록 상기 부식저감물질 분사기를 제어하는 제어부;를 마련하여 보일러 튜브의 직경을 실시간으로 측정할 수 있고, 보일러 튜브의 부식 변화량에 따라 부식저감물질의 투입량을 달리 투입할 수 있으며, 부식저감물질을 부식 변화량에 따라 달리 투입함으로써 보일러 튜브의 부식을 보다 효율적으로 저감시킬 수 있다는 효과가 얻어진다.
