Book Synopsis Coal Dust and Gas Explosion Suppression by Barriers by : A. Furno
Download or read book Coal Dust and Gas Explosion Suppression by Barriers written by A. Furno. This book was released on 1987. Available in PDF, EPUB and Kindle. Book excerpt: Explosion suppression barriers are devices that contain fire extinguishants that are activated to disperse at some critical point during the propagation of an explosion to suppress it. Suppression of coal dust explosions using barriers (both triggered and passive) has been investigated by the U.S. Bureau of Mines. The work reported in the present study is an update of the continuing study of passive barriers of both rigid and flexible construction. Suppressants tested were water and ABC powder (ammonium phosphate). The coal dust mixtures contained 60 to 65% total incombustible matter and were distributed in the Bureau's single entry experimental mine for a total distance of 111 m (365 ft). Dust explosions were initiated by a 7% methane-air gas zone at the face. The passive barriers were located at distances of 60 to 108 m (200 to 356 ft) from the face. At these distances, the magnitude of the explosion pressure pulse was about 0.70 to 1.14 bar (70 to 114 kPa) at the time the flame front arrived at the barrier. With the exception of the powders, the pressure pulse was sufficiently energetic to fracture the troughs and disperse the suppressants.
