Energy audit and waste heat recovery from kiln hot shell

In a cement rotary kiln, high temperature heat is directly dissipated into atmosphere by means of exhaust flue gases and radiation energy through hot kiln shell surface. Heat loss through hot kiln surface by means of radiation and convection mode of heat transfer has a major contribution among all considerable heat losses (average 7–8%) in

Cement Kiln an overview ScienceDirect Topics

The waste-to-oxygen ratios in the exit gases are generally lower in cement kilns than in incinerators (% O 2 is between 2% and 6% in kilns compared to 4% and 12% in incinerators). 3. The raw meal preheat zones of the process serve as a “low-temperature afterburner” with a high surface-to-volume ratio.

The kiln connects with a material exit hood at the lower end and ducts for waste gases. This requires gas-tight seals at either end of the kiln. The exhaust gas may go to waste, or may enter a preheater which further exchanges heat with the entering feed. The gases must be drawn through the kiln, and the preheater if fitted, by a fan situated
