Abstract
A comprehensive set of temperature measurements is presented for coal dust explosions as a function of dust concentration. Data include the dependence of explosion temperature on particle size, volatility, oxygen content, and added rock dust. The majority of the data are for constant volume explosions in a laboratory-scale vessel, but data from a coal dust burner flame and full-scale mine dust explosions are also included. In all of the measurements, the gas temperature was significantly higher than the dust particle temperature. The measurements were made with a three-wave-length near-infrared pyrometer and a six-wave-length infrared pyrometer (in the 1 to 5-um-wave-length region). Some thermocouple measurements are shown for comparison.
