Levy, A V; MacAdam, S

A coal-water, erosion-corrosion, laboratory test project was carried out to determine the comparative material wastage rates of several types of candidate materials for service on the internal walls of the slurry transfer lines of a coal gasifier. The primary governing factor in their performance was their corrosion resistance in both neutral and somewhat acidic slurries; hardness was decidedly a secondary factor. The lowest wastage rate materials were the ceramics with basalt probably being the best overall material tested from a combined performance and cost consideration. The higher chromium steels, which had reasonable corrosion resistance, had somewhat higher but still acceptable wastage rates. The mild steel and surface hardened, low chromium containing alloy steels had similar and quite high material wastage rates, as did a neoprene rubber which was also tested. 3 refs., 21 figs., 7 tabs.
