STUDY OF THE AERODYNAMICS OF THE FLOW OF THE COMBUSTION CHAMBER OF A POWER PLANT WITH VARIOUS SUPPLY OF SOLID FUEL

Numerical modeling methods have been used to study the effect of an emergency stop fuel mixture supply through individual burners on aerodynamics flow in combustion chamber a power boiler. The performed computational experiments made it possible obtain main aerodynamic characteristics heat and mass transfer processes (full velocity vector, pressure, kinetic energy turbulence dissipation energy) volume at exit from mode (two swirl are operating) compare them with traditional solid (basic - four direct-flow working). results obtained indicate that vortex central region chamber, sharp change is observed formation flow, which weakens as pulverized coal products move exit. presence causes stable uniform distribution flows along walls chamber. In addition, nature increases residence time particles contributes more complete burnout decrease mechanical underburning mixture. Such detailed pattern takes place boilers operating TPPs can only be by numerical simulation performing experiments. highly informative make develop “clean” production technologies solve environmental problems emission harmful substances into environment.
