The invention relates to a fuel gas injection type recovery method of sensible heat of convertor coal gas and convertor flue gas, and belongs to the technical field of recycling sensible heat of convertor coal gas and convertor flue gas. The main technical problems to be solved are as follows: on one hand, the water waste problem is to be solved, on the other hand, efficient utilization of physical sensible heat in the convertor flue gas is to be realized, and the effects of eliminating the potential safety hazard existing in the traditional system, greatly improving the yield of convertor coal gas and the like are also to be achieved. The method comprises allocation of a flue heat exchange device, a rough dust removing device and a refined dust removing device, an induced draft fan, a pipe network a control system, and is characterized in that a combustion chamber is arranged in a recovery system, fuel gas is injected into the combustion chamber, a heat exchanger is also arranged in the recovery system and the heat exchanger is installed behind the combustion chamber. The method is suitable for the technical field of recycling physical sensible heat in the convertor coal gas and convertor flue gas, and has the effects of saving energy, saving water, being safe, improving yield of convertor coal gas and the like.
