The invention discloses a calibration method of a pulse type heating furnace. The calibration method comprises the following steps that S1, a target air-coal ratio and coefficients of excess air of asoaking zone, a heating zone and a preheating zone are set; S2, the use amount of a single air burner corresponding to the soaking zone, the heating zone and the preheating zone are calculated according to the standard use amount of a single coal gas burner and the corresponding coefficients of the excess air in the soaking zone, the heating zone and the preheating zone; S3, a target air pressuredifference and a target coal gas pressure difference are reversely calculated corresponding to the soaking zone, the heating zone and the preheating zone; and S4, the air pressure difference of the burners corresponding to the soaking zone, the heating zone and the preheating zone are adjusted and calibrated to the target air pressure difference, and the coal gas pressure difference is adjusted tothe target coal gas pressu
