| Abstract: | There are various scale in the water-cooled condensers,heat-exchangers,boilers and urea high pressure vessels.The types of scale and the deposit reasons are included.The process of chemical cleaning such as off-line cleanig,on-line cleaning and so on is introduced.It has been proved that the chemical cleaning is a very efficient way to prevent and reduce the tendency of fouling and increase the heat-transfer efficiency. |
