Abstract

1,194,689. Controlling converter chimney draught. COMPAGNIE DES ATELIERS ET FORGES DE LA LOIRE (ST. CHAMOND, FIRMINY, ST. ETIENNE, JACOB-HOLTZER). 20 Dec., 1967 [7 Feb., 1967], No. 57914/67. Addition to 1,110,254. Heading F4B. [Also in Division G3] In the waste gas collecting system of an oxygen steel refining process, a damper 5 is controlled to maintain the difference in pressure between the interior of the hood 3 and the ambient air at a value modified by the temper. ature of the gases within the hood. Signals representing the pressures inside and outside the hood 3 are fed to a computer 8 together with a signal representing the temperature in the hood and a signal representing the deviation from a desired value of the level with respect to the pressure measuring point within the hood of the combustion zone or waste gas boundary is used to control the damper.
