Our main focus is to restore and maintain maximum operating efficiency for every condenser and heat exchanger we clean. Hennigan Engineering has the experience required to review your particular conditions and employ the appropriate cleaning technique for every application.
Multiple problems can arise from high air-inleakage, including higher than normal back-pressure, the introduction of dissolved oxygen (which can lead to corrosion inside the condenser), increased heat rates and lost revenue due to the conditions. The increase of back-pressure and heat rates will negatively impact the amount of power able to be produced. Through condenser air-inleakage testing these leaks can be identified allowing for repairs to be made and get your production back to normal.
Under normal conditions even the largest of units can be tested in minimal time, considering that even a slight increase in backpressure can cause hundreds of thousands of dollars in extra operational costs annually. Inspection costs are recovered almost immediately.
Much in the style of condenser air-inleakage inspections, condenser tube leaks are able to be identified through helium leak detection. When hotwell contamination happens, it can cause performance issues, and early system failures in Fossil Boilers and Nuclear Reaction Components and early tube failures in the boiler. The normal process is to remove the suspected tube bundle from service and monitor contaminants.
Once the correct bundle is identified, entry is gained into the waterbox, and the testing process can begin. Plenums of various sizes are used to narrow down areas of suspected leakage down to a single tube. After identifying the leaking tube(s) and plugging, a follow up test is conducted to ensure that the balance of the bundle is free of leakage and the bundle returned to service.
Looking over a long history of Hennigan’s service to Canal Electric Company, I wanted to take the opportunity to commend you for many jobs well done! In an era of uncertainty, it is reassuring to have the certainty of reliability, professionalism, and the commitment of excellence in service.Canal Electric
In conclusion, it is Design Engineering’s recommendation to use Hennigan Engineering to clean any of the-RBS heat exchangers during RF-3 that need cleaning. Hennigan’s past performance plus their patented hydrolasing tip make them the logical choice to use here at RBSRiverbend Nuclear Group
I would like to take this time to express the quality of work that Hennigan Engineering performed during the repair of the USNS Gordon for Boston Ship Repair, Inc. Hennigan Engineering showed professionalism in all aspects of the work that was performed in the shipyard. Work was done in a timely and efficient manner.Boston Ship Repair, Inc.
