Abstract:

The system for measuring oxygen content in coke oven burnt flue gas was introduced, this system can respectively take the samples of burnt flue gas from sole flues of several regenerators, and oxygen content in burnt flue gas was measured with one ZrO oxyen analyzer. In auto mode, automatic measurement of oxygen content in several downflue regenerators can be completed in one reversing cycle; In manual mode, the single regenerator can be continuously measured. The system is characterized by higher measuring accuracy, stronger real time ability, lower cost for investment and less maintenance, which has provided a measuring basis for judging the combustion condition of individual combustion chambers of coke oven.
