Sulphur Dew-Point Corrosion in Exhaust Gases

Abstract Sulphur dew-point corrosion continues to be an important problem in steam-power stations and some gas-turbine applications. A series of corrosion tests is described in which it was found that the effects of this type of corrosion can be minimized by (a) use of certain corrosion-resistant alloys such as Hastelloy C, Carpenter No. 20, or Type 316 stainless steel; (b) the use of low-sulphur fuels; or (c) the maintenance of surface temperatures above the acid-water dew point. The tests indicate that none of the presently available coating materials can provide adequate low-temperature corrosion protection for heat-exchanger surfaces or compressor blading.

The Use of Additives for the Prevention of Low-Temperature Corrosion in Oil-Fired Steam-Generating Units

Abstract Low-temperature corrosion has become an important consideration and presents a real problem in the design and operation of oil-fired steam-generating units. It is caused by the presence of sulphur trioxide in the combustion gases which unites with water vapor and forms sulphuric acid on the cooler surfaces of the unit. Various ways of combating this condition are discussed, with particular emphasis on the use of dolomite as an additive. Test data and the results of actual operating experience are presented which show that additives are effective in reducing the amount of acid formed and, in some cases, practically eliminating cold-end pluggage and corrosion. The economics of their use and the design of units for higher efficiency when using additives also are discussed.
