Pressurized Rotary Kiln With Thrust Containment Allis

Rotary kilns for the commercial production of gas from coal are quite lengthy being of 250 feet or more in length and 12 feet or more in diameter. Additionally, such kilns operate at temperatures exceeding 2,000 F. and pressures of up to 180 pounds per square inch greater than atmospheric pressure.

Cement Kilns Design Features Of Rotary Kilns

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 were …
