The invention provides an automatic heating optimization system for a coke oven. The automatic heating optimization system comprises a feedforward control system and a feedback control system, whereinthe feedforward control system is used for acquiring real-time production data of the coke oven, calculating a set value of a control parameter through an energy forecasting model, and sending the set value to a coke oven control system to realize feedforward rough adjustment; the feedback system comprises a fire fall monitoring system, a mean flue temperature detection system and a waste gas oxygen content detection system, calculates a set value of a control parameter through a fuzzy control model, and sends the set value to the coke oven control system to realize feedback fine adjustment.The automatic heating optimization system for the coke oven calculates a set value of heated coal gas flow of the coke oven by acquiring and analyzing various condition factor variables generated by coking, and instructs heating control of the coke oven and optimizes the heating control, thereby realizing automatic control of uniform heating of the coke oven.
