Numerical simulation on NOx emission characteristic of a 300 MW subcritical coal fired boiler was performed.The effects of such factors as excess air coefficient
over fire air ratio
coal concentration ratio of coal rich side to the lean side and the primary air speed on the furnace temperature field and NOx emission was investigated.The results showed that
with a drop in excess air coefficient and an increase in over fire air ratio
the NOx emission decreased.The higher the coal concentration ratio of coal rich side to the lean side
the lower the NOx emitted.The increasing primary air speed resulted in high NOx emission.After regulation according to the simulation results
