How to avoid problems with poor water flow

2021-10-24View Original

Thread Content

Since the residue in our unit is relatively heavy at present and the coke level in the coke tower is high, we soak the coke for 1 hour before draining water initially. However, to prevent broken coke from falling back and blocking the water drainage line during this coke-soaking process, we avoid stopping the water pump; Adjustment procedure: When the reading on the neutron level gauge at the top rises to 10, reduce the water injection rate into the coke tower from the maximum value of 350–400 t/h to 200 t/h. Continue injecting water for 1.5 hours (an additional 300 tons of water), and then stop the pump to allow the water to drain out. Can this be effectively avoided?
