随着区域供热的发展,特别是采暖热媒基本上采用热水以后,我国热水锅炉的生产发展很快。区域供热的集中锅炉房,或城市热网的调峰锅炉房都逐渐采用热水锅炉,而热水锅炉如何除氧问题,仍是一个没有很好解决的课题。 热水锅炉的炉水,也就是供热系统的循环水,在锅炉内仅是提高共温度,一般炉水不汽化浓缩。因此,相对而言,热水锅炉的防垢措施不如蒸汽锅炉要求严格,但热水锅炉的水侧腐蚀问题要特别加以重视。《低压
With the development of district heating, especially after the heating medium has basically adopted hot water, the production of hot water boilers in our country has developed rapidly. The centralized heating boiler room of district heating, or the peak heating boiler room of the urban heating network has gradually adopted hot water boilers. However, the problem of how to eliminate oxygen in hot water boilers is still a problem that is not well resolved. The boiler water of the hot water boiler, which is the circulating water of the heating system, only increases the common temperature in the boiler. Generally, the boiler water does not vaporize and concentrate. Therefore, relatively speaking, the anti-fouling measures of hot water boilers are not as strict as those of steam boilers, but the water-side corrosion of hot water boilers must be given special attention.
