May 20, 2016· Abstract: In cement kiln lines, significant amounts of NOx emissions can be formed both in the rotary kiln and in the precalciner. To reduce NOx formation, low NOx techniques can be applied to the burner and to the combustion systems used in the rotary kilns and precalciners, respectively.

for the cement industry. The reducing agent is injected at the suitable temperature range either at the kiln inlet chamber or at the calciner (depending on the kiln type and the selected reducing agent). The system is designed to provide sufficient residence time in the required temperature range for the reducing agent to react with the NOx.
