MATHEMATICAL AND EXPERIMENTAL INVESTIGATION OF THERMAL INITIATION OF EXPLOSION.
Abstract
The lead azide reaction chamber was mounted inside the aluminum block, which is the core of the constant-temperature furnace, and tests were run to determine the constancy of temperature inside this furnace. The aluminum block is heated by 24 heaters which are grouped into three zones-two end zones and a central zone. Each zone of heaters has its individual variable transformer so that the power input to each zone may be individually adjusted. Each zone transformer is connected to the main transformer, which is controlled by the Bayley temperature controller. Tests have shown that, for periods up to a week in duration, temperature variations in the center of the furnace could not be detected (Measurements on a 5-15 mv strip-chart recorder). These furnace temperatures are, of course, merely the environment for the reaction chamber which will have its own heater and temperature controller for more precise control. Steps are being taken to isolate the motors and to modify the balance mounting to alleviate the vibrations. (Author)
