More Information
Summary:In a regenerative-combustion heating furnace provided with at least a pair of regenerative burners, regenerators of the regenerative burners or exhaust gas discharge pipes and the like for discharging a combustion exhaust gas are prevented from corroding when the paired regenerative burners are in operation stop. [Solution] In a heating furnace 10 provided with at least a pair of regenerative burners 20 each including a burner portion 21 equipped with a fuel injection nozzle 25 and a regenerator 22 accommodating a heat storage material 22a, 22b therein, when combusting and heat storing operations in the paired regenerative burners are stopped, a combustion air is temporarily supplied to a regenerative burner 20b which is performing, at the time of operation stop, an operation of introducing the combustion exhaust gas into the regenerator 22 and allowing the heat storage material 22b to store heat from the combustion exhaust gas before discharging the combustion exhaust gas.
