The fouling behavior of a steam generator (SG) tube was investigated at different positions after 500 h of immersion in high-temperature water. A triple-layer structure of fouling appeared at both the crevice position and the free span position, namely, the large, dispersedly distributed deposition layer on the top; the small and faceted outer layer; and the relatively continuous inner layer. There was no obvious positional effect on the thickness of the inner layer. However, in the crevice position, the density of the deposited particle and the thickness of the outer layer was much higher than those of the free span position. The tube support plate (TSP) made of 410 stainless steel contributed significantly to the fouling behavior of the SG tube in the crevice between the SG tube and the TSP.

This paper describes a solar energy collector system for providing process heat to a textile drying process in a WestPoint Pepperell mill in Fairfax, Alabama. The solar collector system uses 24 single axis tracking parabolic trough concentrating collectors to heat water in a high temperature water loop. The high temperature water fuels a steam generator to provide process steam. The process that was solarized is a textile drying process using cylindrical can dryers. The dryers are utilized in the slashing operation, a textile process where yarn is treated with sizing in preparation for weaving.

The oxide films formed on non-charged and hydrogen-charged Alloy 690 specimens exposed to 290 °C pure water environment with different dissolved oxygen concentrations were characterized. It was found that the oxide film formed on the hydrogen-charged specimen was thicker than that on the noncharged specimen. Local protruding oxides were observed on the hydrogen-charged Alloy 690 but not on the non-charged specimen. The Ni and Fe contents of local protrusion on the hydrogen-charged specimen were higher than those on the noncharged specimen.
