1. horse shoe flame accumulation of heat kiln comprises:

  • Shell;

    Combustion chamber, said combustion chamber are arranged within the said shell;

    Feed end, said feed end is associated with said combustion chamber;

    First port and second port, said first port and said second port are positioned at said shell place and are connected with said combustion chamber at said feed end place;

    Discharge end, said discharge end are associated with said combustion chamber and separate with said feed end;

    First thermophore;

    Said first thermophore is arranged on said feed end place and is associated through said first port with said combustion chamber;

    Said first thermophore is suitable for cycle operation between ignition mode and discharge mode, in said ignition mode, near the preheated burning air that gets into said combustion chamber through said first port, injects fuel;

    And in said discharge mode, discharge products of combustion from said combustion chamber through said first port;

    The first oxygenated fuel burner assembly;

    The said first oxygenated fuel burner assembly is arranged between said feed end and the said discharge end, and is suitable for when said first thermophore is in cycle operation, between rich fuel mode and poor fuel mode, carries out cycle operation;

    Second thermophore;

    Said second thermophore is arranged on said feed end place and is associated through said second port with said combustion chamber;

    Said second thermophore is suitable for cycle operation between ignition mode and discharge mode, in said ignition mode, near the preheated burning air that gets into said combustion chamber through said second port, injects fuel;

    And in said discharge mode, back warp is crossed said second port and is discharged products of combustion from said combustion chamber;

    The second oxygenated fuel burner assembly;

    The said second oxygenated fuel burner assembly is arranged between said feed end and the said discharge end, and is suitable for when said second thermophore is in cycle operation, between rich fuel mode and poor fuel mode, carries out cycle operation;

    Wherein, The said first oxygenated fuel burner assembly can be worked certain hour at interval when said first thermophore is in said ignition mode, under rich fuel mode;

    In said combustion chamber, to realize fuel-rich combustion and fuel-rich combustion product stream be provided;

    The fuel burner assembly of said second oxidation can be worked certain hour at interval when said second thermophore is in said ignition mode, under poor fuel mode, come to react with said fuel-rich combustion product stream and form the exhaust flow from said combustion chamber so that extra oxygen to be provided;

    After the said timed interval;

    In another time period;

    The said first oxygenated fuel burner assembly is being worked under the poor fuel mode and said first thermophore is worked under said discharge mode;

    And the said second oxygenated fuel burner assembly is being worked under the rich fuel mode and said second thermophore is worked under said ignition mode;

    With said combustion product stream within the said combustion chamber of reversing and said exhaust flow, thereby between said first thermophore and said second thermophore, circulate.
