Abstract: 1369871 Heating shaft kilns IMPERIAL CHEMICAL INDUSTRIES Ltd 25 Jan 1972 [8 Feb 1971] 4122/71 Heading F4B  In a shaft kiln, particularly a kiln for burning limestone or the like, the distribution of heat is controlled by varying the pattern of gas flow over the cross-section of the shaft in a predetermined manner, so that at any instant the heating effect is unsymmetrical about the shaft axis while maintaining the general gas flow direction constant and the overall heating effect symmetrical about the axis. The fuel or air supply to each burner of a ring surrounding the shaft is varied in turn so that the flame front pattern is rotated in steps during a cycle of 5 minutes- 2 hours. The heat pattern may be varied by cyclically varying the withdrawal of air rising through the cooling zone at A, Fig. 6, varying the fuel supply to burners at levels B, D varying the return of air withdrawn at level A through parts at levels C, E, varying the withdrawal of hot gases at levels G and its return at level F, and varying the withdrawal of exit gases at level H. Six symmetrically arranged parts are provided at each level, and the Specification gives details of the state of each part in each of twelve periods in a half hour cycle. The opening or closing of each part is under the control of programming apparatus, and the duration of any fixed mode of operation in a cycle is between one and ten minutes. Possible flame frount patterns at any instant of burners at levels B and D are shown in Figs. 4 and 5.
