Abstract Benefits to be gained from the use of higher steam temperatures in oil-fired boilers warranted a laboratory investigation of oil-ash corrosion of superheater alloys. The laboratory program included the use of differential thermal analysis techniques and pilot plant corrosion tests. With differential thermal analysis, solidification temperatures lower than melting temperatures were observed for actual and synthetic oil-ash deposits. This temperature difference was correlated with oxygen absorption. An ash composition was found which could be liquid and probably corrosive at metal temperatures as low as 895 F. A relationship was presented to correlate fuel and deposit compositions. By using the DTA technique, magnesium oxide-vanadium pentoxide reactions were studied. 4.2.3, 7.6.4
