Reducing NOx from existing cement kiln lines IEEE ...

20/05/2016  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. These low NOx techniques have the dual advantage of (i) low CAPEX cost and (ii) no additional operating cost.

01/07/2021  Thermal NOx formation is very high in the rotary cement kiln due to high-temperature flame. Essentially all NOx emissions associated to the cement manufacturing are formed in cement kilns. In this paper, the effects of natural gas injection into calciner exhaust, i.e., rotary kiln inlet, on NOx reburning by CO and CH radicals is numerically and experimentally investigated. A 3D model of ...

NOx Emission Reduction by Advanced Reburning in Grate ...

16/11/2020  Many studies have shown that NOx formation in rotary kilns occurs in the flame, due to either the high temperatures (thermal NOx) or the oxidation of the fuel-bound nitrogen [13,14]. When coal is combusted in iron-ore rotary kilns, the NOx formation is dominated by the conversion of char-N to NO [15,16]. At present, NOx emission reduction is mainly accomplished through reducing the injection ...
