ABSTRACT:
The heat supplied to a cracking furnace is controlled in response to a calculation of the heat required to maintain a desired conversion rate for the material being cracked in the cracking furnace. The calculated required heat for the cracking furnace is corrected by a comparison of the actual conversion rate to a desired conversion rate. The corrected required heat signal is utilized to manipulate the flow of fuel to the cracking furnace to thereby control the heat supplied to the cracking furnace.
