A pulsed burner was designed to provide sufficient heat to convert a fluidized bed of black Kraft liquor into combustible gas which would be used to produce process steam. The pulsed burner design provides a significant increase in the heat transfer capability and consequently significantly increases the efficiency of the conversion process. High temperature corrosion tests were performed in a fluidized bed of black Kraft liquor using a pulsed burner process to determine the optimum materials for use in a commercial application. The materials tested included three different austenitic stainless steels, Type 446 martensitic stainless steel, a high temperature carbon steel, 153MA, and four nickel base alloys. All materials performed well with no corrosion attributed to the environment created by the decomposition of a black Kraft liquor. This behavior was contrary to what was expected due to the high concentration of H{sub 2}S present in the high temperature, 562 C, atmosphere.
