The invention provides a rapid judgment method of abnormal local heating of a coke oven. The rapid judgment method comprises the following steps: a) setting detection equipment capable of detecting content of CO, SO2 and particulate matters in a chimney with a height, which is 6 to 7 times as much as the diameter of the bottom of the chimney, from the coke oven; b) when a rudder stock at a coal gas side or an air side is blocked, sending out alarm when detecting that the CO content in flue gas of the coke oven is continuously excessive and keeps more than 450mg/m for 4min or more; confirming that the rudder stock at the coal gas side or the air side is blocked by an operator and treating; c) when a carbonization room of a furnace end part has inter-leakage, controlling an indoor part to send out alarm when the content of the CO, the content of the SO2 and the content of the particulate matters exceed pre-set values; judging whether the carbonization room has the inter-leakage or the blocking is caused by the
