Abstract A simple model is developed for relating fuel volatile release to flame stability in a suspension-type industrial burner fired with pulverized coal. Convective transport and mixing processes are represented by assigned mass flows and time scales, based upon global flow field characteristics. This can adequately represent controlling parameters, while avoiding the computational issues of a priori prediction of complex viscous flows. Particle thermokinetic phenomena are treated in detail. The model allows the investigation of the effects of such burner design parameters as physical size, fuel throughput, wall radiation, mixing time scales and air injection sequence. Operating parameters including particle size distribution and volatile yield behavior and heating value can be explored in detail, as a means of assessing fuel interchange, for example. The proportioning of primary and secondary air streams, air preheat, and oxygen enrichment can also be explored using this approach to flame stability modeling.
