In this paper, a comprehensive 3D mathematical model for rotary cement kiln including heavy fuel oil combustion, hot flow, zone heat flux model for clinker formation and rotating wall was developed.

The advantages of the rotary kiln are: (1) uniform heating and high heat transfer efficiency. The solid materials are heated in the uniformly rotating cylindrical kiln body, which move reversely against the gas; (2) large equipment scale, high operation continuity, and large production capacity; (3) stable product quality; (4) low energy consumption and less …

This study provides a systematic description and results of a dynamical simulation model of a rotary kiln for clinker, based on first engineering principles. The model is built upon thermophysical, chemical, and transportation models for both the formation of clinker phases and fuel combustion in the kiln. The model is presented as a ID model with counter-flow between …

Clinker: reactions in the kiln. The milled and blended raw materials go to a silo and then to the kiln. Reactions which take place as the feed passes through the kiln are reviewed below. They …

fluid flow, temperature, etc,) from within the cement rotary kiln, which is a benefit to better understanding of combustion behavior and an improvement of burner and rotary kiln technology. Introduction In the modern cement industry, the rotary kiln is key equip-ment widely used to produce cement clinker. To meet the

Cement production has been one of the most energy intensive industries in the world. In order to produce clinker, rotary kilns are widely used in cement plants. This paper deals with the energy audit analysis of a dry type rotary kiln system working in a cement plant in Turkey. The kiln has a capacity of 600 ton-clinker per day.
