The damage factors are mostly poor equipment, low or high pressure bag, the bag from the top blowing in the porous plate or dust cover, eventually friction damage.
The damage factor is too high, the compressed air blowing pipe deflection, flower plate deformation and other factors, can be adjusted to prevent breakage.
破损因素是压缩空气过高、喷吹管歪斜、花板变形等因素构成，调整后即可防止破损。

After shutdown, the high-pressure plate-fin heat exchanger is recovered to normal run after elimination of the drag through back-blowing of its oxygen passage.
