Abstract

This paper presents results from a series of experiments involving the intermittent exposure of several steels to a CO-based gas mixture containing 0.1% H(2)s for periods of upt o 1000 hours. The flow of the gas was maintained at a rate sufficiently high to prevent equilibriation of the mixture occuring at the reaction temperature of 550 degrees Celsius, thereby simulating conditions found in commercial coal gasification plants.

Corrosion kinetics are presented in terms of weight change and metal loss measurements indicating the significant improvement accompanying the addition of 1-2% Si to the basic 12% Cr composition. The contributions of ash deposits and periods of moist down-time are also discussed.
