✦ Synopsis

Predictions from the Distributed-Energy Chain Model (DISCHAIN) are compared with transient volatiles yields for heating rates between 103 and 105K/s and ultimate temperatures between 1000 and 2100K. All model parameters were assigned by correlating transient volatiles yields for much lower heating rates and temperatures, and no further adjustments have been made. Predicted reaction time scales and yields agree quantitatively with the behavior in an atmospheric entrained-flow pyrolysis study, an atmospheric entrained-flow study of the initial stages of coal combustion, and a fuel-rich, one-dimensional coal flame.
