With increasing interest in the burning of coal in industrial gas turbines, there is also concern for the determination of the erosive effects on the turbine components. In order to provide the basis for alloy selection in future turbines using coal, an investigation is undertaken to obtain a basic understanding of the mechanisms of erosion at high temperatures. For this purpose, test equipment has been designed to simulate the aerodynamic and thermodynamic conditions in the turbine. Data were obtained for 304 stainless steel, Rene 41 and A286 alloys at temperatures between ambient and 1200/sup 0/F. In addition, the equations that govern the three-dimensional motion of the solid particles suspended by a compressible gas flow through a rotating cascade of a turbomachine, are formulated. These equations are solved for the case of flow through a turbine stage. The solution takes into account the loss in particle momentum due to their collision with the turbine blade casing. The results obtained from this study indicate the locations on the turbine blades subjected to erosion damage.
