Abstract: Provided is an alternate-switching regenerative combustion apparatus, comprising at least three regenerative burners 2 communicating with a furnace hearth 101 which is provided in a furnace body 1, a controller for controlling the regenerative burners 2, a fuel gas pipeline 401, a combustion-supporting gas pipeline 402, a flue gas pipeline 403, and a reversing valve 5, wherein each of the regenerative burners 2 includes a burner nozzle 3 and a regenerative chamber 208. The burner nozzle 3 is in communication with the fuel gas pipeline 401. The regenerative chamber 208 has one end in communication with the furnace hearth 101 via the burner nozzle 3, and another end in communication with the combustion-supporting gas pipeline 402 and the flue gas pipeline 403 respectively via an air inlet 201 and a smoke vent 202.
