Erosion of the entry stages of high- and intermediate-pressure turbines and reheat steam turbines by solid oxide particles originating in the boiler is a significant problem in fossil-fueled utility power plants and is well documented.1-3 The American Society of Mechanical Engineers (ASME) established a task group of representatives from utilities and manufacturers under the Steam Power Panel to study the problem. A questionnaire was sent to 37 utilities in August 1978 to attempt to ascertain the economic importance of the problem and identify possible solutions. Results of this survey should be available soon.
