SUMMARY AND RECOMMENDATIONS: Boiler was inspected to establish baseline conditions following vendor change. Slight deposition and uniform reddish coloration were noted. Samples were taken for analysis and graph #1 is attached outlining the results. Based on the laboratory analysis indicating high phosphate levels in the deposits, and the elimination of phosphate feed in the current chemistry program it is probable that the chips sampled were old scale being removed from the tubes. See Figure 6. Maintaining proper polymer levels will aid greatly in controlling deposition moving forward and continued reduction in deposit thickness on heat transfer surfaces. Maintaining adequate hydroxyl alkalinity will establish a magnetite film preventing/reducing reddish color.
