The invention discloses an energy-saving environment-protective regenerative heating furnace, which comprises a furnace body. The inside of the furnace body is provided with a hearth; the sidewall of the furnace body is provided with at least one set of burners; each set of the burners consists of a first burner and a second burner; the first burner is connected with one end of a first gas branchpipe; the other end of the first gas branch pipe is connected with a c port of a first three-way change valve; the second burner is connected with one end of a second gas branch pipe; the other end of the second gas branch pipe is connected with an f port of a second three-way change valve; an a port of the first three-way change valve and a d port of the second three-way change valve are connected with a gas source through a pipeline respectively; a b port of the first three-way change valve is connected with one end of a first smoke branch pipe; an e port of the second three-way change valve is connected with one end of a second smoke branch pipe; a control valve is arranged between the first gas branch pipe and the second gas branch pipe; and the control valve is connected with an inert gas source. The energy-saving environment-protective regenerative heating furnace solves the problem in the prior art and has good effects of energy conservation and emission reduction.
