Abstract
The paper deals with simulation study of aerodynamics and heat transfer for a case of a four-vortex furnace chamber designed for jet fire of brown coal from Eastern coal deposits. The combustion modeling is achieved by a set of linked submodels: they describe turbulent gas flow? Thermal and radiative heat transfer, the processes of degradation and burning of coal particles, NOx generation. Simulation demonstrated that using of these types of brown coal in a specific-design furnace chamber creates a steady four-vortex flow structure that provides a uniform temperature field in the volume and admissible generation of NOx .
