The influence of the Songhua River water quality on the fouling resistance in heat transfer process was studied. The water quality variation in the heat transfer was measured in three types of heat exchange tube
including a general circular tube and two enhanced tubes
alternating elliptical axis tube and discrete double inclined ribs tube. The measured water quality parameters are pH
alkalinity
conductivity
DO
Ca2+ and Fe2+ concentrations. The fouling resistance is correlated with the water quality parameters with the gray correlation method. The results show that the parameter correlation order is the same for the two enhanced tubes. The variation tendency of fouling resistance is the same as two of the water quality parameters and opposite of the other parameters. Compared with circular heat exchange tube
the enhanced heat exchange tube affects not only the water quality parameters
