In hydrocarbonization research cold model tests are being conducted to determine conditions that will enhance mixing in the recirculating fluidized bed reactor and make it more suitable for the hydrocarbonization of caking coals. In the pressurized carbonization of Consol Synthetic Fuel residue, five runs were completed that show a desirably low rate of coking of the recycle solvent that is used to slurry the residue. Fracture toughness studies of thick steel plates are continuing. The effects of important welding variables such as current, travel speed, and torch oscillation on the depth of penetration and dilution of type 320 Cb stainless steel cladding deposits have been evaluated for deposits made by the submerged-arc process. A 1000 hr exposure of heat exchanger tubes to the fluidized bed combustion conditions of a Fluidyne bed was started. Inconel 600 tubing failed by catastrophic sulfidation after a few days. In the gas-fired potassium boiler project, the major portion of the potassium piping installation was completed and connections of the electrical and instrument wiring between the control room and the system are being made. In the coal-fired alkali metal power system design study, several variations of the cycle arrangement for the selected atmospheric pressure fluidized bed combustor were completed, a preferred concept for the furnace developed, the coal feed and ash handling system was designed, and work continued on the alkali metal condenser-steam generator.
