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
This optimisation of thermal efficiency allows a large output for which the rolling action of the rotary kiln is Not all precalciner kilns are strictly
Because of their poor thermal efficiency rotary kilns particularly large ones are often fitted with energy saving devices For example the combustion air may be preheated by channeling it through the hot material leaving the kiln and the hot gases leaving the kiln may be diverted to preheated feedstock or to raise steam in a waste heat boiler
In rotary kilns heat transfer mode is dominated by thermal radiation increase rotary kiln efficiency by refractory design Among the many factors involved in rotary kiln efficiency advantageous use of refractories is of major importance So far as kiln lining alone is concerned durability is most significant as shutdowns for repairs are
