Two blocks of Pittsburgh seam bituminous coal were pyrolyzed under reducing gas in the project in support of in situ gasification. Higher heating rates appear to reduce swelling of the block during pyrolysis, and higher final pyrolysis temperature results in lower boiling tars. Three pressurized residue carbonization tests were completed at 1100/sup 0/F and 400 psi of methane with three feed materials. Work is in progress on the fracture toughness of thick sections of steels for piping and pressure vessels in coal conversion plants. Modifications to experimental techniques have been made to allow the heat treatment of tension specimens and simulated heat treatment of thick plate sections. Exposure of heat exchanger tubes in the Fluidyne Corporation atmospheric fluidized bed has reached a maximum of 1500 hr. Tube samples have been recovered and are being characterized. In the gas-fired potassium boiler project, three preliminary runs of short duration were made in which the boiler was filled with potassium and heated up to or near the boiling temperature with the main burner. Operating problems that were encountered in these runs have been resolved. ORNL has been requested by DOE-FE to develop a program for testing coal feeders currently under development. In the project for landfill storage of solid wastes, samples of solid wastes from all pilot plants are being obtained. (LTN)
