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.

In this case study, the corrosion failure analysis of high-pressure boiler water-wall tubes in a power plant was investigated by means of the chemical analysis, metallographic examination and scanning electron microscope (SEM) observation. Energy dispersive spectroscopy (EDS) was used to examine the changes of test materials and corrosion products. Based on the failure process of the boiler water-wall tubes and the experimental results, a conclusion was drawn that the failure of water-wall tubes was mainly caused by pitting corrosion. Sulfide and chloride attack was the major cause of localized pitting corrosion on the inner surface, and the outer surface damage was mainly due to the synergism of high temperature sulfide corrosion and flue gas erosion.

The world-wide crisis caused by the Coronavirus disease 2019 (COVID-19) pandemic had a significant impact on the global economy functioning and the sustainable development of supply chains. The changes also affected seaports being the key links of maritime supply chains. The purpose of the research study described in this article was to identify the sources and kinds of disruptions observed in various maritime supply chains as a result of the COVID-19 pandemic and their impact on the operations of various types of seaport terminals, namely those serving bulk (universal, specialised) and general cargoes (universal, specialised). An additional purpose was to identify the dependencies between the type of terminal and its main function, and the tactical decisions adopted by the particular terminals. The research was carried out using the multiple-case study method. The study covered some selected port terminals functioning in Polish seaports (Gdańsk, Szczecin, Świnoujście), applying direct, semi-structured in-depth interviews. The analysis of the results was carried out using the inductive reasoning method. The research study has shown that as a result of the COVID-19 pandemic some maritime supply chains ceased to exist, some of them were operating with decreased cargo volumes, while in other cases the transshipment volumes actually rose during the pandemic. Among terminal operators’ tactical responses to disruptions in maritime supply chains, there were pro-active and adaptive measures. Pro-active (offensive) measures included actions taken by an enterprise in order to engage in new maritime supply chains, and even participating in establishing new maritime chains in response to limitations caused by the pandemic. Adaptive (defensive) measures covered actions taken by the port terminals as a consequence of changes in the existing maritime supply chains, caused by the pandemic in the port’s foreland or hinterland. The research study results revealed that the terminals extent of engagement and tactical decisions related to the pandemic were depended on the type of terminal (universal or specialised) and its main function played within a supply chain.

NYU has an ongoing research program which is being funded by DOE to test three types of high-pressure, high-temperature filters. The main objectives of the testing program are: (1) to establish the performance capability of the filters under high-pressure and high-temperature conditions; and (2) to evaluate the dust collection efficiency. Shakedown tests for a duration of about 50 hours was completed during October 1986. Testing of the electrostatic precipitator (ESP) is in progress. The first test with ESP was performed during the middle of November 1986. The operating experience with respect to the test facility, and in particular with the particulate sampling systems, is reported in this paper. Additionally, some test results are also discussed.
