1. a port regenerative furnace, it comprises:

  • Shell;

    Be arranged on the combustion chamber in described shell;

    The feed end be associated with described burner;

    At the first port and second port at described shell place, its for the described combustion chamber at described feed end place;

    Be associated with described combustion chamber and the discharge end separated with described feed end;

    Be arranged on described feed end and by the first regenerator of described first port and described combustion chamber, described first regenerator is adapted at circular flow between roasting pattern and exhaust mode, wherein, in described roasting pattern, fuel is through spraying the pre-heated combustion air close to entering described combustion chamber through described first port, in described exhaust mode, combustion product is discharged from described combustion chamber by described first port;

    Be arranged on described combustion chamber half and closest to the first spray gun assembly of described discharge end, described first spray gun assembly be suitable for only burner oil gas fuel gas pattern and and the concurrent oxygen pattern of only spraying oxygen of the circular flow of described first regenerator between circular flow;

    Be arranged on described discharge end and by the second regenerator of described second port and described combustion chamber, described second regenerator is suitable for circular flow between roasting pattern and exhaust mode, wherein, in described roasting pattern, fuel is through spraying the pre-heated combustion air close to entering described combustion chamber through described first port, in described exhaust mode, combustion product is discharged from described combustion chamber by described first port;

    AndBe arranged on described combustion chamber half and closest to the second spray gun assembly of described discharge end, described second spray gun assembly be suitable for only burner oil gas fuel gas pattern and and the concurrent oxygen pattern of only spraying oxygen of the circular flow of described second regenerator between circular flow;

    Wherein, described first spray gun assembly can run in the fuel gas pattern concurrent with the roasting pattern of described first regenerator, to provide fuel-rich combustion and the fuel-rich combustion product stream in described combustion chamber, and described second ejection assemblies can run in the oxygen pattern concurrent with the exhaust mode of described second regenerator, to provide with the aitiogenic extra oxygen of described fuel-rich combustion product reaction stream and to form exhaust stream from described combustion chamber;

    Described first spray gun assembly then can run in described oxygen pattern and described first regenerator can run in described exhaust mode, and described second spray gun assembly can run in described fuel gas pattern and described second regenerator can run to be reversed in the combustion flow in described combustion chamber and exhaust stream that circulate between described first regenerator and the second regenerator in described roasting pattern.
