Numerical simulation of aerothermal processes in 500 MW block boiler furnace with nazarovskiy coal as a primary fuel

Low-temperature vortex combustion technology was researched. FIRE-3D software package was used for combustion simulation in P-49 boiler of Nazarovo power plant with excess air ratio alpha=1,072 and fuel rate Вр=39,444 kg/s. Aerodynamics, oxygen concentration and temperature fields were calculated and represented in graphical form. Obtained results show necessity of follow up research of combustion technology.
