THERMAL CONDUCTIVITY OF Q-FELT INSULATION AT ELEVATED TEMPERATURES
Abstract
The thermal conductivity of Q-felt, a commercial micro-quartz fibrous insulation material, was evaluated. Tests were conducted on several densities each of as received and thermally stabilized material at elevated temperatures and at atmospheric and reduced pressures. Mean test temperatures ranged from 200 to 2560 F and reduced pressures to 0.1 mm/mercury were used. Curves have been prepared presenting the mean apparent thermal conductivity of both thermally stabilized and unstabilized Q-felt as a function of mean temperature, gas pressure and material density.
