The invention provides a burner arrangement for a reduction reactor 100, wherein the burner arrangement includes multiple burners 200 placed in a wall 101 of the reduction reactor, to allow an internal temperature in the reduction reactor 100 to reach more than 1200 ° C, where the reduction reactor 100 has a reaction space formed therein, where the burner has a fuel feed hole 210 and multiple oxygen feed holes 220 formed therein, where each burner 200 has a portion head 201 thereof having an elongated combustion space 202 formed at one end thereof, combustion space communicates by fluid with the reaction space of the reactor, wherein the elongated combustion space has a length such that the oxygen supplied from the oxygen supply holes to it is completely consumed by oxidation or combustion with co fuels supplied from the fuel feed port to it, only in the elongated combustion space after lighting the burner, where unburned fuels and H2O molecules and / or CO2 molecules generated through the oxidation reaction in the Elongated combustion space is flowed into the reaction space of the reduction reactor, where only a reduction reaction of the H2O molecules and / or CO2 molecules occurs at a temperature above 1200 ° C using the heat of radiation generated by the burner. In addition, the invention provides a synthesis gas recycling system comprising: the burner arrangement for the reduction reactor as defined above; a cooling and compression module 400 configured to cool and compress the collected synthesis gas through a gas collection line 121 from the synthesis gas outlet 120; a storage tank 500 configured to receive and store the compressed and cooled gas of the cooling and compression module 400, and to supply the stored gas to the array of burners 200, to thereby allow recycling of the synthesis gas; and an oxygen generator 600 configured to generate oxygen and supply oxygen to the oxygen supply holes 220. |
