It is found that the fouling rate is lowered during subcooled fow boiling by carrying gas injection, and the influence of carrying gas injection on fouling of convective heat transfer is more obvious than that of subcooled flow boiling; morphology of CaCO〓 crystallization fouling exhibits self-similarity and the fractal dimensions of CaCO〓 crystallization fouling are determined from the gray scale distribution of the SEM images by box-dimension method. The value of the crystallization fouling surface fractal dimensions reveals the complexity of the surface, and can be used as an import parameter for the investigation of influence of carrying gas injection on scale formation.
