Vibration of the auxiliary economizer in the 190t/h dry quenching system
Thread Content
Our company operates a 190 t/h dry quenching system with a designed air flow rate of 272,000 Nm³/h; under normal operation the air flow rate is 245,000 Nm³/h. During operation, a buzzing vibration sound is heard. The cause identified is ash accumulation on the surfaces of the tubes inside the economizer, which reduces the area available for air flow and leads to resonance. How can this be avoided?
It’s been changed, so what else can be done? What sticks to it isn’t just ash; it’s as hard as armor.
