Condenser Unblocked – Hard Calcium Deposit Removed

Bespoke unblocking jets assist condenser tube cleaning

Summary

Blocked tubes on a weak acid condenser were effecting production at a UK based fertiliser manufacturing plant. A traditional high pressure water jetting contractor had failed to unblock the condenser tubes and had also been unsuccessful in the cleaning of lightly scaled tubes. Tube Tech cleaned the condenser using their bespoke unblocking jets and their unique WysperFlex™ pump.

Challenge

• Approximately 40 tubes on a weak acid condenser were believed to be blocked by a hard calcium type deposit.
• The remaining 2041 condenser tubes has been cleaned by a traditional high pressure water jetting contractor but there was still some scale left inside the tubes.
• The condenser featured triangular pitch tubes and is usually cleaned every 3 years.

Solution

• Once on site the Tube Tech technicians found 83 condenser tubes to be completely blocked with calcium scale.
• Using their SafeTrak™ jetting unit with their WysperFlex™ pump the Tube Tech team were able to unblock the blocked tubes and then remove the scale from the additional tubes quickly and effectively
