    The measurement of oxygen (O 2) 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 NO X. Maintaining a consistent oxygen level can prevent variations in product quality. The zirconium oxide (ZrO 2
