摘要：PURPOSE: An apparatus for controlling an amount of oxygen in waste gas of a coke oven which automatically adjusts the amount of air supplied into combustion chambers for the complete combustion inside the combustion chambers of the coke oven. CONSTITUTION: In an apparatus for controlling an amount of oxygen in waste gas of a coke oven equipped with one or more combustion chambers, the apparatus comprises a waste gas detection part(34,35) detecting oxygen in the waste gas and the amount of oxygen discharged from the combustion chambers; a control part(31) producing a control amount by comparing an amount of oxygen in the waste gas detected in the waste gas detection part(34,35) with an already set oxygen amount in the waste gas(a target value); a control amount driving part(30) producing power for controlling depending on a control amount produced in the control part(31); and a combustion air opening and closing part(21) equipped with a means for opening or closing an air passage into the combustion chambers so as to control an amount of combustion air supplied into the combustion chambers(20) after receiving power from the control amount driving part(30).
