Title: Limits of flammability of pulverized coals and other dusts

Abstract

The limits of flammability of pulverized coals and other dusts were measured in a 7.8-liter laboratory-scale system that provided for accurate control of the significant experimental variables. Internal optical probes were initially used to develop an improved dust dispersion method. One probe was then used to routinely monitor the dust concentration prior to ignition. The problem of ignition source strength was resolved by independent assessments of the ignition energy requirements for realistic limit measurements for each dust. The carbonaceous dusts studied span the extremes from a completely volatilizable polyethylene powder with an H/C ratio of 2, to a low volatility anthracite with an H/C ratio of 0.3. 25 refs.
