Zusammenfassung:	To provide a fire sensing system, fire sensing method, and program with which it is possible to identify the position of a fire using a low number of sensors. A fire sensing system 1 provided with: gas sensors 11a, 11b, 11c for sensing a change in gas concentration at three locations P1, P2, P3; a gas propagation speed calculation unit 12 for sensing gas concentration increase times T1, T2, T3 at the three locations P1, P2, P3 and calculating the gas propagation speeds v1, v2, v3 at the three locations P1, P2, P3; and a fire information estimation unit 13 for estimating the position of the fire on the basis of the gas concentration increase times T1, T2, T3 and the gas propagation speeds v1, v2, v3.
