    摘要： The present invention relates to a technique for separating carbon dioxide from waste gas discharged from a blast furnace, sending the carbon dioxide to a regenerative chamber of a hot stove, and decomposing same by using heat energy stored in the hot stove regenerative chamber and heat of combustion of methane gas supplied from outside. Or, the present invention relates to a technique by which, when carbon dioxide and methane gas are sent to a hot stove regenerative chamber by the present invention, the carbon dioxide and the methane gas are decomposed into carbon monoxide and hydrogen gas by means of stored heat and heat of combustion, and when the decomposed carbon monoxide and hydrogen gas are re-sent to a blast furnace, same take on the role of a reducing gas for reducing iron ore.

    摘要： The invention provides a burner array for a reduction reactor 100, wherein the burner array includes multiple burners 200 disposed on a wall 101 of the reduction reactor to allow an inner temperature in the reduction reactor 100 to reach above 1200°C, wherein the reduction reactor 100 has a reaction space formed therein, wherein each burner has a fuel feeding hole 210 and multiple oxygen feeding holes 220 formed therein, wherein each burner 200 has a head portion 201 thereof having an elongate combustion space 202 formed at one end thereof, the combustion space fluid-communicating with the reaction space of the reactor, wherein the elongate combustion space has a length such that oxygen supplied from the oxygen feeding holes thereto is completely consumed via oxidation or combustion with fuels supplied from the fuel feeding hole thereto only in the elongate combustion space upon igniting the burner, wherein non-combusted fuels and H 2 O molecules and/or CO 2 molecules generated via the oxidation reaction in the elongate combustion space are flowed into the reaction space of the reduction reactor, where only a reduction reaction of the H 2 O molecules and/or CO 2 molecules occur at the temperature above 1200°C using a radiation heat generated from the burner. Further, the invention provides a synthesis gas recycling system comprising: the burner array for the reduction reactor as defined above; a cooling and compressing module 400 configured to cool and compress the synthesis gas collected via a gas collection line 121 from the synthesis gas outlet 120; a storage tank 500 configured to receive and store the cooled and compressed gas from the cooling and compressing module 400, and to supply the stored gas to the burner array 200, thereby to allow synthesis gas recycling; and an oxygen generator 600 configured to generate oxygen and supply the oxygen to the oxygen feeding holes 220.
