Study Results

This report is the second in a series of three describing the progress of “A Research Study on Internal Corrosion of High Pressure Boilers.” The first progress report, presented by H. A. Klein and J. K. Rice at the 1965 Annual Meeting of the ASME, describes the background, scope, and organization of the program as well as the test facility. This second progress report describes the results of the first half of the study. Results of tests with volatile, coordinated phosphate, and caustic boiler water treatment under conditions simulating a boiler with clean internal surfaces and one whose surfaces have been fouled with typical preboiler corrosion products, are included. Data relating to deposition and corrosion in the aforementioned environments are presented. The corrosion failure of a test tube due to “caustic gouging” and the discovery of an unusual effect of deposits on boiling characteristics are described.

The following report is the third and last in a series describing the progress of “A Research Study on Internal Corrosion of High Pressure Boilers.” The first report described the background, scope, and organization of the program as well as the test facility. The second report discussed the methods of testing and the results of the first six runs. This final report describes the results of the last six tests and discusses the conclusions drawn from all of Phases II and III. The scope and an outline of seven tests composing the newly scheduled Phase IV program are also included. The results of runs with three types of boiler water treatment, fouled heat transfer surfaces, and conditions simulating fresh water and seawater condenser leakage are included. Data relating to deposition and corrosion in these environments are presented with particular emphasis on the severe corrosion experienced with simulated seawater condenser leakage.

The following report is the last in a series of four describing the progress and results of “A Research Study on Internal Corrosion of High Pressure Boilers.” The first three reports described the background, scope, and organization of the program, as well as the test facility and the results of Phases I, II, and III. This final report includes results of the eight Phase IV tests and a discussion of the results and conclusions from the entire program. Phase IV test results include data and observations on plug-type corrosion and hydrogen damage. The discussion of results describes the mechanisms involved in these types of attack, as well as the causes of caustic gouging. Observations on chemical hideout and deposition are discussed in addition to the heat transfer and fluid flow phenomena involved in nucleate boiling and departure from nucleate boiling.

We examined all articles in volume 139 and the first issue of volume 140 of the Journal of the American Society for Horticultural Science (JASHS) for statistical problems. Slightly fewer than half appeared to have problems. This is consistent with what has been found for other biological journals. Problems ranged from inappropriate analyses and statistical procedures to insufficient (or complete lack of) information on how the analyses were performed. A common problem arose from taking many measurements from the same plant, which leads to correlated test results, ignored when declaring significance at P = 0.05 for each test. In this case, experiment-wise error control is lacking. We believe that many of these problems could and should have been caught in the writing or review process; i.e., identifying them did not require an extensive statistics background. This suggests that authors and reviewers have not absorbed nor kept current with many of the statistical basics needed for understanding their own data, for conducting proper statistical analyses, and for communicating their results. For a variety of reasons, graduate training in statistics for horticulture majors appears inadequate; we suggest that researchers in this field actively seek out opportunities to improve and update their statistical knowledge throughout their careers and engage a statistician as a collaborator early when unfamiliar methods are needed to design or analyze a research study. In addition, the ASHS, which publishes three journals, should assist authors, reviewers, and editors by recognizing and supporting the need for continuing education in quantitative literacy.
