Abstract
An improved method of optimum burning of carbon monoxide in a carbon monoxide zone (being fed oxygen by a side tuyere) above a molten metal bath in a converter to carbon dioxide is disclosed. The improved method includes the steps of: A. sensing an initial effectiveness signal of the amount of carbon monoxide in the carbon monoxide zone being burned to carbon dioxide at a predetermined point relative to the converter; B. monitoring a continuing effectiveness signal; C. comparing the continuing effectiveness signal with the initial effectiveness signal; and D. moving the side tuyere relative to the converter and adjusting O.sub.2 flow when all possible side tuyere positions are exhausted when the continuing effectiveness signal is greater than the initial effectiveness signal to increase the amount of carbon monoxide in the carbon monoxide zone being burned to carbon dioxide. The apparatus has sensing means associated with the converter for sensing the initial effectiveness signal of the amount of carbon monoxide in the carbon monoxide zone being burned to carbon dioxide at a predetermined point relative to the converter. The sensing means is then operable to monitor the continuing effectiveness signal. Comparison means are connected to the sensing means for comparing the continuing effectiveness signal with the initial effectiveness signal. Tuyere operating means are connected to the comparison means and the side tuyere for moving the side tuyere relative to the converter and adjusting O.sub.2 flow when the continuing effectiveness signal is greater than the initial effectiveness signal to increase the amount of carbon monoxide in the carbon monoxide zone being burned to carbon dioxide.
