Abstract:

The large deviation of the flue gas flow field uniformity at bag filter entrance in a domestic 1000MW ultrasupercritical oncethrough boiler leaded to the startup of its water spraying desuperheating system and affected its safe and efficient operation.The deflector was installed based on the numerical simulation and onsite test. After installation, the uniformity of the flue gas velocity and temperature at the bag filters entrances is improved obviously.
