with copper and brass tubes (particularly combined with ferrous sulphate dosing) in salt water; additionally with evaporators of MSF-Plants.
in power stations:
without FeSO4 dosing: 6–12 balls/day and tube
with FeSO4 dosing: from 6–12 balls/day and tube to 6–12 balls/week and tube
in MSF plants:
2 balls/hour and tube with a ball number of 30 % of the number of tubes of the first evaporator stage
Due to the roughness of copper-alloy tube surfaces, the cleaning ball type S220 may also be applied as long-life ball (L220).
