PROBLEM TO BE SOLVED: To provide combustion equipment of an exhaust gas re-combustion type, having improved energy efficiency as a whole while suppressing a lack of air during change-over from a normal combustion condition to a temporary combustion condition. SOLUTION: A blowing means F is constituted by an induction blowing means 13 for sucking combustion air through a combustion air induction passage 12 with sucking operation on a combustion chamber 21 and supplying it to a burner B. A combustion control means 1 is constructed to be changeable over between a normal control condition, where an induction passage opening/closing means 19 for opening/closing the combustion air induction passage 12 is put into a closed condition to allow the operation of the induction blowing means 13 so that suction force on the combustion chamber 21 is stand-by suction force smaller than combustion amount equivalent suction force to suck the combustion air in amount equivalent to the combustion amount of the burner B, and a temporary control condition, where the induction passage opening/closing means 19 is put into an opened condition to allow the operation of the induction blowing means 13 so that the suction force on the combustion chamber 21 is the combustion amount equivalent suction force.
