TY - JOUR ID - TI - The Ovality Problem in Cement Kilns (A Numerical and Experimental Study) AU - Montadher A. Muhammed PY - 2012 VL - 12 IS - 2 SP - 238 EP - 265 JO - Iraqi journal of mechanical and material engineering المجلة العراقية للهندسة الميكانيكية وهندسة المواد SN - 20761819 AB - The Ovality phenomena which occurs in cement kilns was studied by using anumerical method based on F.E. techniques with the help of software (Pro-Engineer4),the theoretical results was compared with practical one, the temperaturedistribution for kiln shell was measured by kiln shell scanner. The results showed thatthe dangerous value of Ovality which cause bricks cracking and falling was 7 cm andup, as well as, the maximum axial stresses was concentrated on the last hot quarter at14 cm distance of brick. The largest Ovality was found in the burning zone at tireNo.1 which was responsible for coating come off and in turn brick damages. Theresearch include suggestions in order to reduce the Ovality phenomena.
