| description | To solve the serious problem of residual swirl of flue gas and gas temperature deviation between two sides at furnace outlet in a 330MW tangentially fired boiler, a numerical simulation on combustion under multiple conditions was proposed. The effect of SOFA nozzle tilt angle on the residual swirl and gas temperature deviation of furnace exit was carefully studied. In addition, a monitoring system for cross-section temperature fields at furnace exit was designed. Four flame detectors were installed on a section of furnace exit. Through processing flame radiative image, the temperature fields of the section were detected. Combined with field experimental conditions, the SOFA nozzle vertical angle experiment was carried out with detection system. The results show that as SOFA nozzle swings downward, it is beneficial to weaken the residual swirl of flue gas and reduce the gas temperature deviation of boiler. |
