Abstract
152,106. Lesley, R. W. July 4, 1919. Rotary furnaces; retort furnaces. - The hot waste gases from a rotary cement kiln a<1> are used to heat retorts d containing low-grade carboniferous materials, such as oil shale, lignite, lowgrade bituminous or cannel coal, &c. The volatile products from the retorts may be passed along a pipe e and burned in the kilns or may be used for other purposes, and the ash or residue is added to the calcareous or other ingredients and submitted to the clinkering process, the carbon in the residue forming a part at least of the fuel required in the process. The ash or residue from the retorts is carried by a conveyer f to a hopper c to which the cement-making materials are supplied and the mixture is passed therefrom into the kilns. The kilns are heated initiallv bv fuel supplied by a pipe b. Specification 11618/91 is referred to.
