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 …

The burning zone area of the kiln lining, while in operation, is to withstand (1) high temperature, (2) clinker liquid infiltration, (3) flame impingement, (4) thermal cycling, and (5) redox reaction. The stable coating formation on the refractory lining provides: 1. Protection to the refractory lining from overheating and temperature fluctuations.
