Beschreibung
Zusammenfassung:	An improved furnace for heating or heat-treating of particulate materials, the furnace having an elongated body, preferably vertical, forming a triskele cylinder having a desired cross-sectional area defined by four (4) circles of identical diameter, a central circle, and three (3) tangential outer circles, the center of each tangential circle symmetrically placed 120 degrees about the central circle, each of said circles being connected by tangential arcs of about the same diameter as the circles. The furnace shell is a high performance corrosion resistant nickel-base alloy, including cobalt, chromium, and silicon, whereby the critical contents of cobalt and silicon provide improved sulfidation resistance.
