Summary:

The purpose of this project is to compare a limited number of candidate ceramics proposed for use in the air heater of a coal fired high temperature advanced furnace (HITAF) for power generation. This work will provide necessary initial structural ceramic parameters for design of a prototype system. Phase 1 of the work consisted of evaluation of the mechanical properties of three structural ceramics at high temperatures in air and a preliminary evaluation of mechanical properties of these structural ceramics after exposure to coal ash. This work was described in a final report, and the results will serve as baseline data for further work. An initial screening of candidate structural ceramics with respect to their creep properties in air at selected temperatures will be performed as Phase 2, and temperatures above which creep may become a design problem will be identified. Tubes and tube sections of the candidate ceramics will then be exposed to a combination of mechanical loads, coal ash exposure and high temperature, and corrosion behavior, mechanisms and post exposure mechanical properties will be evaluated.
