Problems resulting from the use of high sulphur-containing petroleum residues as fuel for the boilers at the Jeddah desalination plant are reviewed. During combustion, sulphur trioxide was formed which condensed on the cooler regions of the combustion chamber and chimney, especially during operation at reduced output, while the soot emitted from the stack and deposited on neighbouring premises was also acidic and hence corrosive. Extensive compilations of data concerning flue gas temperatures, fuel/air ratios, atmospheric emissions are given to emphasize the intractable nature of the problem. Noticeable improvements in flue gas composition and properties were obtained in response to the use of a CPI fuel additive consisting of a slurry of magnesium hydroxide in oil containing 22 per cent weight per weight of magnesium. Results of short-term trials of the additive at levels of 500 and 750 ppm in the fuel at reported, indicating that significant benefits could be achieved at the 750 ppm level.
