Heat transfer to fine bituminous coal particles suspended in argon has been studied by recording infrared emission from the coal as a function of time at wavelengths 3.42 and 2.26/am when the coal was subjected to very rapid heating by a shock wave. The rate of particle beating was found to fit a Nu
