Summary:PROBLEM TO BE SOLVED: To provide a combustion monitoring device and combustion monitoring method for a heating furnace capable of sensing an abnormality (clogging and leakage) of fuel and combustion air related to a regenerative burner, and a combustion control system capable of preventing misfire etc. caused by incomplete combustion and enabling stable combustion. SOLUTION: The combustion monitoring device includes: a determination part 140 sending out an abnormality signal when at least either of pressure of fuel in routes of piping 11, 12, 13, 14 corresponding to pressure switches 51, 52, 53, 54 or pressure of combustion air in routes of piping 61, 62, 63, 64 becomes lower than a predetermined lower limit pressure value; and a warning issuing part 142 for issuing a warning based on the abnormality signal sent out from the determination part 140.
