Abstract
The factors influenced the distribution of temperature and velocity field was numerically studied with realizable k-ε model in a 1000 MW ultra supercritical boiler. The results indicate that the ring way of pulverized coal feeding feed powder can form the short and wide flame shape, combustion stability is better; the center way can form the long and narrow flame shape, combustion stability is worse. The concentration NO emissions decrease slightly. The simulation results can coincide with the practical combustion process. All of these can provide a theoretical basis for the HT-NR burner design and operation.
