Reduction of dust deposition in air-cooled condensers in thermal power plants by Ni–P-based coatings

Abstract One of the largest problems with most current thermal power plants is cooling efficiency. This paper aims to massively reduce fuel consumption and heat wasted in hence CO 2 emissions by resolving fouling issues associated air-cooled condensers. In order dust deposition condensers, finned flat tubes were coated nickel−phosphorus nickel−phosphorus−polytetrafluoroethylene (Ni–P-PTFE) an electroless coating technology. The anti-fouling performance was investigated using field operation parameters influence surface energies coatings on adhesion also investigated. results demonstrated that Ni–P performed best, which reduced resistance 83.3% compared untreated tubes. have potential applications for reducing exchanger significantly decreasing waste emissions.
