Flow direction of the catalyst in the external heat exchanger
Thread Content
The external heat exchanger in our plant is controlled by air; according to our team leader, there is upper fluidization air, lower fluidization air, and lift air. However, the air volume supplied by the lifting fan in our factory is not particularly high. Could the experts please tell me how the catalyst flows inside? Thank you so much! ! !
It depends on the type of external heat exchanger, which can be divided into upflow and downflow types.
Our company’s model is pneumatically controlled
The upward type has flow from bottom to top, while the downward type has flow from top to bottom
