Observing the Calcining Process of Rotary Kiln

Henan Hongxing Mining Machinery Co., Ltd.

The calcining process of petroleum coke within the rotary kiln is a complex physical and chemical reaction of flotation, heat transference, medium transference and movement of materials, so there are many parameters that can influence the operation of calcining petroleum coke by rotary kiln.


The optimized design and economic operation of rotary kiln are mainly influenced by the flotation of gas and solid materials, heat transference, medium transference and chemical reaction, and the heat transferring mathematic model is just an important way to learn the temperature spread and heat characteristics of rotary kiln.

Utilized the methods of numerical calculation, the heat-transfer mathematic model is solved.

The results from the numerical calculation predict temperature profiles for the solid bed, the gas phase and the kiln wall, in addition the gas and solid bed composition in the axial direction.

And then the rules of countercurrent heat transfer between the gas phase and the solid bed caused by physical changes and chemical reaction processes that take place in the limestone rotary kiln are studied.

At the end of this dissertation, some rational proposals are put forward for design and operation of petroleum coke calcining rotary kiln.

The direction for further improvement in this research field and the development trend of mathematical model of heat transfer for rotary kiln are prospected.

The results of this dissertation can be used to guide the optimum design and the economic operation of petroleum coke calcining rotary kiln.


Therefore, it is better to know the thermotechnical parameters of the rotary kiln, relationship among the structural parameters, the operational parameters, the heating technology and the production quota.

The results of this dissertation greatly improve the level of the optimum design and the economic operation of petroleum coke calcining, decrease the burning loss of carbon, improve the product quality of calcined petroleum coke, cut down the consumption of energy, furthermore, reduce production costs of petroleum coke calcining, and gain obvious economic performance and social benefits. http://sandmakerhongxing.blog.com/
