Tests were begun to determine helium heat-transfer coefficients at 1600 and 2100 deg F and 100, 175, and 250 psig. The helium film coefficient rangad from about 10 to 40 Bta/hrft/sup 2/- deg T as the Reynolds number was increased from approximately 2300 to 6500, Frequent plugging of the gasifier coil has hindered attempts to continuously operate the life-test apparatus with lignite- water sluries. Other methods of feeding the lignite and steam were stadied. Tests were made to determine the weight loss of porous carbon (for use in the ISR) in static and in flowirg helium at 2150 to 2640 deg F. Investigations with the tungsten tester show that concentration of oxygen in the contaminant is the most significant variable that affects the tester in the anaysis of oxidizing impurities in hellum. The effects of H/sup 2/O, 02, CO/sub 2/, and CO on the wolfram fliamnent at 2500 and 3200 deg F were determined. Tests were begun with the redesigned toal gasifler heat-exchange section but extended operating periods could not be attained because of plugging of the slurry preheater. Anxiliary heating devices were installed in the pracipitator system so that tests can be conducted at temperatures of 1200 to 15OO deg F. (auth)
