METHOD FOR REFORMING EXHAUST GAS GENERATED FROM METALLURGICAL FURNACE, METHOD FOR COOLING EXHAUST GAS AND APPARATUS THEREFOR |
摘要 |
<p>A method for reforming high-temperature exhaust gas from a metallurgical furnace which comprises adding a reducing agent to the exhaust gas to reform the gas, wherein the addition of the reducing agent is initiated when the oxygen concentration of the exhaust gas reaches 1vol% or below and the reforming reaction is completed when the temperature of the exhaust gas is 800°C or above; an apparatus for the process. The reducing agent is blown into the reforming system through a reducing agent blowing nozzle having a double pipe structure. Further, the invention provides a method for cooling exhaust gas from a metallurgical furnace, which comprises adding a reducing agent to high- temperature exhaust gas from a metallurgical furnace, causing endothermic reaction between the reducing agent and carbon dioxide contained in the exhaust gas, and cooling the exhaust gas itself by the endothermic reaction; and an apparatus for the process.</p> |
