| Abstract | ||
| The Ovality phenomena which occurs in cement kilns was studied by using a numerical method based on F.E. techniques with the help of software (Pro-Engineer 4),the theoretical results was compared with practical one, the temperature distribution for kiln shell was measured by kiln shell scanner. The results showed that the dangerous value of Ovality which cause bricks cracking and falling was 7 cm and up, as well as, the maximum axial stresses was concentrated on the last hot quarter at 14 cm distance of brick. The largest Ovality was found in the burning zone at tire No.1 which was responsible for coating come off and in turn brick damages. The research include suggestions in order to reduce the Ovality phenomena. | ||
