​Paint-based protective films (PPFs) are applied to the internal surface of steam surface condenser
tubes to mitigate corrosion and erosion, thereby extending condenser life. Mr Goodenough has
designed, built, and operated a portable test facility at a power plant, to experimentally measure
the fouling performance characteristics of these films. Tests were performed over 185 days on
several tube alloys with and without PPFs. This work has led to better understanding of the
temporal fouling behavior of PPFs and the significant negative impact of biofouling on electric
power output. Implementation of the findings measurably reduces negative environmental
impact.​
