Rotating Kiln an overview ScienceDirect Topics

The TOSCO (The Oil Shale Corporation) process used a rotating kiln that was reminiscent of a cement kiln in which heat was transferred to the shale by ceramic balls heated in an exterior burner (Figure 4.6) (Whitcombe and Vawter, 1976).The process, which was initiated in the 1960s and 1970s and developed by the Oil Shale Corporation, is more correctly described as a retorting/upgrading process

Cement Kilns: Rotary kilns

In the Dry Process, the kiln system is fed with dry raw meal powder. In the Semi-Dry Process, a limited amount of water (10-15%) is added to dry raw meal so that it can be nodulised, and the damp nodules are fed to the kiln system. In addition to these distinctions, a further category has emerged in the last 40 years: Precalciner Kilns, in

The method of waste incineration of The Rotary kiln type

1. As the waste is not easy to decompose in the process of treatment, the incineration rotary kiln equipment required to be used must have strong thermal bearing capacity. 2. The kiln body of the incineration rotary kiln equipment can withstand the corrosion of the corrosive gas generated by the waste after incineration for a long time. 3.
