Heat E changers Rotary Kiln Indirect Heat Calciner


Indirect Rotary Calciners, Heat Transfer Equipment An indirect rotary calciner can be supplied either gas, oil or electrically heated, and usually feature multiple furnace zones. In an indirectly heated calciner, the process material is isolated from the heat source consequently heat transfer and the process atmosphere composition/volume are independent.

Analysis of Local Heat Transfer in Direct Fired Rotary ...


Heat transfer in the rotary kiln is a complex phenomenon due to the different modes of heat transfer. In the first part of this study, the local heat transfer coefficients are analysed theoretically, to describe the heat transfer mechanisms in the cross section of the rotary kiln.

"Heat Transfer Model and Computer Program for a Direct ...


An improved heat transfer model has been developed for a directfired rotary kiln. The model can be used to verify Kiln design, to optimize operating conditions, to predict the temperature history of the solids, and to evaluate if local areas of the kiln will be overheated. The treatment of radiant heat transfer was based on the Reflection Method developed by Succec and applied by Gorog, and ...

Rotary Dryer Schenck Process


The rotary dryer design consists principally of a rotating cylinder that is enclosed in a furnace along its active length. With heat transfer indirect and through the cylinder wall, the gas velocities within an indirect dryer are low as compared to a direct heat dryer, and correspondingly, the offgas system is smaller and more economical.
