Chemistry and Properties of Slags from Navy Solid Waste Destruction in the Plasma Arc System
Abstract
The U.S. Navy is currently developing a highly efficient shipboard system which employs a plasma torch to process Navy solid wastes primarily consisting of cardboard, paper, steel, aluminum, glass, and food waste. The objective of this research was to experimentally determine the melting behavior and properties of the slags resulting from the waste stream containing all five components, as well as various excursions. This study also investigated the corrosion resistance of various classes of refractories to resulting slags. A severe thermite reaction was observed in the "zero glass" excursion of the waste stream at about 1200 degrees C as a result of the chemical interaction between iron oxides and aluminum. This suggests the critical importance of the presence of a glass melt for suppression of the reaction.
