In　this　paper,　we　carried　out　some　experiments　on　fouling　characteristics　of　spiral　grooved　tubes　and　smooth　tube　in　many　kinds　of　experimental　conditions　and　parameters　of　spiral　grooved　tubes.　As　compared　with　the　smooth　tube,　the　spiral　groove　tube　has　a　good　anti-fouling　propertiy　in　higher　hardness　of　water,　higher　cold-water　inlet　temperature　and　lower　cold-water　flow　velocity.　And　we　have　found　a　kind　of　spiral　grooved　tube　which　has　a　good　anti-fouling　in　a　variety　of　conditions.　©　2011　IEEE.
