Oxygen Measurement Improves Efficiency And Product Quality In Cement And Lime Kilns

The measurement of oxygen (O2) inside a rotating kiln provides a good indication of combustion efficiency. This oxygen measurement can also provide an inferred indication of calcining rates and the production of thermal NOX . Maintaining a consistent oxygen level can prevent variations in product quality.

The zirconium oxide (ZrO2)measurement technology has become the standard for measuring oxygen in any combustion processes. A measurement accuracy of +/- .05 % O2 is achievable, and the sensing cells are very robust. However, some application difficulties hamper getting a suitable measurement of oxygen in a rotating kiln.
