抄録

Three kinds of materials applied to PFBC boiler have been examined in the atmosphere of the mixed gas (N2-O2-SO2), and the effect of atmosphere gas on hot erosion waste of the materials was studyed. The results obtained are as follows.<BR>(1) The erosion waste of materials is accelerated by SO2, and is restrained by O2.<BR>(2) The erosion waste is small on the condition of low testing velocity below 7m/s.<BR>The erosion waste becomes larger in proportion to the increase of the testing velocity on the condition of the high velocity beyond 7m/s.<BR>(3) The erosion waste becomes smaller at larger Cr content because of a formation of Cr oxide at the most inner layer of an oxide scale.
