Preliminary tests with the Induction-heated SimulatedNuclear Reactor revealed that tubes of kt silicon carbide, silicon carbide foam, and normal silicon carbide are not suitable for use in the Process Heat Reactor. To prevent the siliceous deposits formed, the sphere container was constructed of a Zirconia tube lined with porous carbon. After 1000 hr, leakage from the helium recycle loop was only 3 to 4 std. c.f.h. A laboratory-scale loop was constructed to study the characteristics of a helium-graphite suspension recycle system. A single spiral coil of stainless-steel tubing was tested to determine its ability to withstand continuous operation in the Process Heat Reactor system at 1700 deg F. A lignite slurry was pumped through the coil for 114 hr before the coil plugged. Subsequent examination failed to reveal the cause of plugging. A heliumheated coal gasifier was developed to demonstrate the feasibility of gasifying steam-coal mixtures with heat transferred from hot recycled helium. Dust was removed from gases at elevated temperatures and pressures with an electrostatic precipitator. Removal efficiencies exceeded 99% for all tests at 5 to 80 psig and 1200 deg F. (M.C.G.)
