โœฆ Synopsis

Silicon monoxide is released when various mixtures of silicates and carbon arc heated above rzoo". On leading this into a coal gas flame containing sulphur oxides the initial high dewpoint due to the presence of sulphur trioxidc is reduced. Similar results arc obtained when a silica smoke is produced by the disintegration and subsequent oxidation of alkyl silicates sprayed into the flamc. The significance of dcwpoint measurements in the presence of silica smokes is discussed and it is considered that there is a definite reduction in the sulphur mioxide content of the combustion gases. The mechanism whereby this is brought about is discussed. ' D ~a l ~y , A. and Whittingham, G., Trans. Faradny SW. I9#, 429 354

It is now well established that the presence of small amounts of sulphur impurity in a NiCrAl-based alloy causes a deleterious effect on their high temperature oxidation behaviour. It is, however, not clear whether the adverse effect is due to a decrease in the spalling resistance of the oxide scale
