Abstract

309,298. Gordon, K., and Imperial Chemical Industries, Ltd. March 31, 1928. Cements, Portland and Roman, materials and compositions for. - In a process for the joint manufacture of sulphuric acid and cement from calcium sulphate, carbonaceous materials, and siliceous materials, the air for the combustion of fuel in the cement kiln, and that for the subsequent oxidation of sulphur dioxide, are admitted separately. Air slightly in excess of that required to burn the fuel is passed into the kiln and the resulting gases after removal of dust, enter the Glover tower at 250-300‹ C., and are mixed with an additional quantity of air before being passed to the lead chambers.
