摘　　要：在供热企业热力网系统设计中,有少数选用热水锅炉供热的单位没有设计使用换热器,采用锅炉热水直供热用户的供热方式。循环水量特别大,很难保证其水质量,使热网管道里面的杂质流经管径较小的锅炉受热面管道时,不可避免地会粘附到管壁上。日积月累造成堵塞管道,从而造成管道过热、爆管,给锅炉带来了非常大的危害,严重影响了锅炉寿命及生产运行安全。In the heating network system design of heating enterprises,there are a few units that use hot water boiler to heat the system without using heat exchangers,but use the heating method of boiler hot water direct heating users.The circulating water volume is particularly large,so it is difficult to ensure its water quality,so that the impurities in the heat supply network pipeline will inevitably adhere to the pipe wall when passing through the boiler heating surface pipeline with small pipe diameter.Time accumulation causes blockage of the pipeline,resulting in overheating and explosion of the pipeline.It brings great harm to the boiler and seriously affects the boiler life and the safety of production and operation.

关 键 词：换热器 安全 爆管 炉水质量 锅炉寿命
