Abstract

The upper operating temperature of tubes in heat exchangers/steam generators is strongly influenced by the degradation that can occur because of the reaction of the exchanger/generator tubing with the deposits that accumulate on the surface of the tubes. In fact, severe corrosion has been observed in some biomass fired systems, particularly when the potassium and chlorine contents of the deposits are significant. The corrosion behavior of alloy steel tubes as a function of temperature has been investigated by exposing samples of selected alloys to ash collected from the steam generator of a system fired by syngas that was produced in wood gasifiers. Results of the corrosion studies as well as information about the corrosion mechanisms will be presented.
