In a kiln whose interior is heated by combustion with oxidant having a higher oxygen content than air, streams of staging oxidant are fed into the space between the combustion zone and the inner surface of the kiln, and the stoichiometric ratios and amounts of oxygen in the combustion zone and in the overall operation of the kiln are adjusted to provide control or reduction of NOx formation while maintaining or increasing productivity of the kiln.
