Numerical study of aerodynamics and brown coal combustion in the vortex furnace with air excess variation

The results of numerical modelling of 3D turbulent two-phase reacting flow with account for all the principal heat and mass transfer processes during the pulverized brown coal combustion in the vortex furnace of a power plant boiler unit have been presented. For two computational cases where air exc...
