Supported by the National Science Foundation in a SBIR Phase II grant, NBD has coated 30 foot long tubes and piloted partially retubed a live power plant. The tubes were placed in triplets at 10 different locations of the condenser box, with a control tube in the middle of each triplet and sensors to determine the improvement of Overall Heat Transfer Coefficient (U). NBD’s technology is easily scalable due to simple application process, and offers superior durability due to NBD’s expertise in surface wettability coatings.
Next steps include a partial retube (>25%) of condenser with use of a manufacturer. Please contact NBD if interested in implementing technology during next retubing for fuel savings and boosts in overall system efficiency. Other applications include but are not limited to: Desalination, Distillation, & Power.
