近年来热水采暖技术已被社会接受并广泛受到欢迎。但是通过几年的实践也发现了一些值得研究的问题。首先是热水锅炉的腐蚀问题。有些单位因循环水质管理不善,补充水量过多,溶解氧所造成的腐蚀非常严重,3~5年间,即达到腐蚀穿孔漏水者屡见不鲜。其次是汽改水的卧式锅壳式快装锅炉,后管板胀口漏水,锅筒底部鼓疱裂纹,后管板孔
In recent years, hot water heating technology has been accepted by the community and widely welcomed. But after years of practice, I also found some problems worth studying. The first is the corrosion of hot water boiler. Some units due to poor circulation of water quality management, add excess water, dissolved oxygen caused by the corrosion is very serious, 3-5 years, that is, to achieve corrosion perforation leakage are common. Followed by steam to water horizontal boiler shell fast boiler, after the tube plate expansion mouth leakage, drum bottom blister crack, after the tube plate hole
