近年来远距离集中供热取得明显进展,因为这样不仅可以节约能源,更重要的是可以减少环境污染。人们早就知道,在液体中加入活性剂可以减少液体在管道中的流动阻力,从而提高流量和增加供热量。但是由于添加剂有腐蚀性,引起了管道腐蚀和泄漏污染等问题。同 In recent years, significant progress has been made in long-distance centralized heating, because this will not only save energy, but more importantly it will reduce environmental pollution. It has long been known that the addition of an active agent to a liquid can reduce the flow resistance of the liquid in the pipe, thereby increasing the flow and increasing the heat supply. However, due to the corrosive nature of the additives, problems such as pipeline corrosion and leakage pollution are caused. with
