The heat exchange efficiency of the slurry heat exchanger deteriorates, and it is not possible to raise the preheating temperature

The heat exchange efficiency of the oil slurry-to-feed oil heat exchanger in my catalytic unit has declined, which prevents the feed oil from reaching its desired preheating temperature. The normal temperature should be 230 degrees, but currently it can only be maintained at 220 degrees. It’s not possible to shut down the oil slurry heat exchanger at the moment, and the planned maintenance is scheduled for October next year. Are there any ways to increase the preheating temperature?

Is it blocked? Raise the slurry temperature?
