Two devolatilization tests were conducted to explore devolatilizer operability over a range of operating conditions using a low-sulfur, mildly caking Indiana coal from the Minnehaha mine of Amax Coal Company. In the first test the system was operated for over 30 hours at temperatures of 1400 to 1800/sup 0/F and at a pressure of 225 psig with a fluidized bed of char. An analysis indicated that about 94 percent of the volatile matter in the coal was removed. Some fixed carbon was gasified as a consequence of the water vapor content in the inlet gases. The second test provided additional steady-state data on heat and material balances, char characteristics and reactor system operation. Reactor operation was sustained for over 12 days and produced reliable design data. Support work was carried out to investigate operating conditions for the PDU test program, provide troubleshooting capability for PDU operation, obtain data for PDU modifications, analyze and interpret results from PDU operation and develop information for future process development. The coal behavior test program was directed toward obtaining devolatilization data as a function of coal particle size and tests on coals used in the PDU tests. Two tests were run with Canaan dolomite to study its resistance to disintegration resulting from thermal shock in charging, from temperature cycling in the bed, and from partial calcination. Work on solids transport, the intermediate scale test facility and reactor analysis was carried out. Limited gas turbine combustion experiments with oil and low Btu gas are reported. (LTN)
