I personally believe every coker behaves different, depending on many factors, being most evident: feed quality, heaters efficiency, fractionator wash oil section design, TPR, and T,P conditions, etc..others less evident are, additional steam consumption, additional flush oil consumption, blowdown limitations, HKGO filters operation, and in general everything may affect your coke drum superficial velocity.
Only after doing a concious review of design parameters and making sure everything is running to the optimum, then ramping heaters at the end of the cycle may help mitigate foaming issues. I have found similar problems due to excessive steam velocity in heaters and just adjusting back values to normal design was enough to get out of the foaming problems.
