PROBLEM TO BE SOLVED: To provide an exhaust gas reforming system capable of accurately performing sufficient recovery operation for recovering catalytic poisoning. SOLUTION: This exhaust gas reforming system 400 includes an air-fuel ratio adjusting means 40, a reformed gas passage 130 for carrying a catalyst for generating reformed gas, a heating means 140 for heating the reformed gas passage 130, an introducing passage 110, a fuel injection means 120 and a communicating passage 150. The reformed gas passage 130 includes a reforming means 100 having a heat exchange part 132 for exchanging heat with the heating means 140 and an extension part 134 extended from the heat exchange part 132, a heating temperature detecting means 170 for detecting the temperature of a heating medium used for heating the reformed gas passage 130, a catalyst bed temperature detecting means 180 arranged in the extension part 134 and detecting the bed temperature of the catalyst, and a control means 200 for controlling the air-fuel ratio adjusting means 40 and the fuel injection means 120 so as to perform reforming operation and recovery operation.
