Abstract

The angle of burner nozzle is an important factor for burning of ultra-supercritical tower boiler. In this paper, gassolid multiphase flow and combustion in 1000MW Ultra-supercritical tower furnace were of the numerical simulation under different conditions. The angle of burner nozzle deflects downward, and the angle is 0°, 3°, 6°, 9° and 12°. Flow model is turbulence and SIMPLE algorithm and QUICK scheme are employed. Through theoretical analysis of different conditions (the velocity distribution in different face; the velocity vector in furnace; the temperature in furnace; the NOx, CO2 and O2 emissions in outlet), finally, the law of the angle of burner nozzle for flow field and heat transfer in ultra-supercritical tower boiler is found.
