    This means longer opera- tion periods and less down-time for these systems and reduced refractory costs com- pared to SP kilns. Generally the maintenance costs are lower for a single-string kiln system than for a double or triple-string system. Furthermore, the risk of cyclone blockage is reduced with fewer cyclones

    The early commercially successful rotary kilns in Britain were nearly all straight cylinders, the exceptions being those at Norman (1904). Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to 1914, only 15 out of 44
