Abstract
On a project to develop a system to suppress coal dust explosions, a facility has been built and several devices tested. The facility is a 317-foot, 4.5-Foot-diameter shock tube. To date 53 tests have been carried out with methane-air and methane-coal dust-air as the explosive mixtures. The suppression of slowly propagating (up to 300 ft/sec) flame fronts has been successfully carried out on two tests using the dry chemical extinguishing agent purple k. Delivery of the material directly into the flame front seems to be required if effective suppression is to be accomplished.
