APPARATUS FOR TREATING EXHAUST GAS CAPABLE OF REDUCING A COST REQUIRED FOR ELIMINATING NITROGEN OXIDES FROM EXHAUST GAS BY LOWERING THE TEMPERATURE OF THE EXHAUST GAS IN CASE OF THE ELIMINATION OF THE NITROGEN OXIDES

摘要

PURPOSE: An apparatus for treating exhaust gas is provided to improve the efficiency of the apparatus by increasing the sensible heat collecting rate of the exhaust gas.;CONSTITUTION: An apparatus for treating exhaust gas includes a plurality of wind boxes(21), an exhaust gas duct(25), and a heat exchanger(35). The apparatus treats exhaust gas from an iron ore sintering process which is continuously implemented according to the movement of a conveyor(13). The wind boxes are in connection with each part of the conveyor and collect the exhaust gas. The exhaust gas duck is in connection with the wind boxes and transfers the exhaust gas to a nitrogen oxides eliminating unit. The heat exchanger heat-exchanges the exhaust gas from the rear part of the sintering process.;COPYRIGHT KIPO 2012
