Abstract

This research aims to study the problems of the rotary kiln of al Kufa cement plant. The heating process of the furnace starts by burning a certain amount of wood near the fuel outlet inside the rotary kiln to provide the initial combustion process of the heating oil at (80-100°C). Then the front fan of the furnace is operated while the heating process is continuing for 24 hours. The most important problems that appear during the use of the rotary kiln were: mechanical wear, thermal wear and chemical wear. These problems have been diagnosed and taking the necessary treatments to reduce them, whereas the operational limits must e observed during the operation. When mechanical, thermal or chemical problems occur they will result high torque furnace that causes the risk of the main vehicles of the rotary kiln.
