The effects on various refractories of the combustion products of No. 6 residual oil containing a high concentration of vanadium was determined. Other major oil impurities were Na, Ni, P, Si, and S. The specimens included magnesia-based bricks and mortar, alumina-based bricks and castables, and alumina-based fibrous insulations. The test was conducted in the Refractory Test Facility at 1375/sup 0/C for 510 h with 5.7 to 7.5% excess oxygen. After the test the specimens were analyzed to determine the extent of reaction with fuel impurities. None of the refractories were seriously degraded by reaction with fuel impurities. The least volatile fuel impurities (as oxides) were found most frequently in the specimens. Thus, nickel- and vanadium-bearing compounds were found in most specimens. Most of the dense refractories cracked during the test, but the magnesia-bricks and mortar cracked most extensively. The magnesia-based brecks and mortar darkened, but there was no evidence of degration, even on the hot face.
