Program to discover materials suitable for service under hostile conditions obtaining in equipment for the gasification of coal and other solid fuels. Annual progress report, January 1, 1975 to December 31, 1975
Coal gasification plants are expected to have a range of hostile environments from room temperature to 2000/sup 0/F and from atmospheric pressure to 1500 psi with atmospheres containing highly corrosive constituents. Corrosion data in the literature available is inadequate to permit the selection of materials for many of these environments. A materials screening program designed to give the reliable corrosion data needed to assist in materials selection is described. The program is being pursued in five phases, the first four being conducted by IITRI under the direction of The Metal Properties Council steering committees. Phase I consists of laboratory corrosion studies in gasifier environments at temperatures in the range of 900-2000/sup 0/F and a pressure of 1000 psi for exposure times up to 5000 hr. Phase II involves the exposure of both alloys and refractories in selected locations of the Hygas, Consol, Synthane, and Bigas pilot plants. Phase III is a laboratory program of testing for times up to 400 hr. at temperatures up to 462/sup 0/F and pressures up to 1210 psi in aqueous gas-quench solutions typical of various pilot plants. Phase IV is a laboratory erosion-corrosion test program using char, ash, or dolomite as the erodent. A tentative program for Phase V was developed and circulated for bids. Proposals received have been reviewed, and are now being appraised. (auth)
