We raise the heater outlet temperature 5 F and we see significant reduction in foaming.  If you are running the coke drum inlet temperature below 900 F and are having foaming, try raising the temperature.  A few degrees makes a big difference. 
 
The theory is that the higher temperature increases the rate of the cracking reaction which therefore decreases the froth on top of the coke drum.
