Abstract

PURPOSE: To make exhaust gas denitrating apparatus for a coke oven etc. unnecessary by utilizing NOx-contg. exhaust gases from coke oven in an iron mill, a thermoelectric power plant, etc. as air for an iron ore sintering machine to reduce the NOx to N in the reduction zone of the machine.
CONSTITUTION: Hot exhaust gases from coke oven 1, hot stove 2 and thermoelectric power plate 3 are used as air for iron ore sintering machine 7 together with air or oxygen 4. Since the exhaust gases contain NOx, denitrating apparatus are set usually to reduce the NOx to N. In macine 7 the NOx are reduced to N in the reduction zone of a sintering layer. NOx generated in the oxidation zone of machine 7 are, however, reduced to N in denitrating apparatus 9. By this system denitrating apparatus for coke oven 1, etc. are made unnecessary, thereby lowering equipment and denitration running costs.
