Abstract:
A study of the kinetics of 503 formation has been undertaken in a liquid fuel fired, non-catalytic quartz tube combuster. The effects of excess air, residence time, gas temperature, and steam injection on the level of 503 produced have been investigated. A non-catalytic quartz tube combuster was built with the required safety precautions. Provisions for maintaining near isothermal conditions along the tube and also injecting steam into the combustion chamber were made. An electrically heated temperature controlled chamber evaporated the fuel which was mixed with air and passed through a stainless steel sintered disc and a flat flame was produced just outside the disc. A kinetic study of 503 formation was done with a laminar flame and it was found (a) the excess air, (b) the residence time, (c) the gas temperature all had effects on the formation of 503 in the fluegases. Sulphur trioxide concentration was determi ned by a chemical wet method. The effect of steam injection on the formation of Sulphur trioxide was investigated and shown that steam injection in the flame could provide a method of reducing 503 and hence a reduction of corrosion. The maximum amount of 503 reduction was found to be about 14% when steam was injected at 17.5 mm from the origin of the flame.
