Formation and Techniques for Control of Sulfur Dioxide and NO TROUBLE WITH NOx A TEC Cement Pyroprocess
Operating alterations that may reduce SO2 emissions include an appropriate arrangement of the burner system to provide the necessary O2 for efficient combustion and flame orientation It must be noted that oxidizing conditions in the burning zone that limit SO2 emissions are favorable for the generation of nitrogen oxides NOx in the rotary kilnfor 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

Reduction of NOx emissions from rotary cement kilns by NOx Reduction Review on Fuel Alternative in Cement Kiln
Mar 17 32 In yet another of its aspects the invention provides an apparatus for reducing NO x emissions from rotary cement kilns by selective noncatalytic reduction comprising an injector capable of propelling prills of urea at speeds of at least 25 eg greater than 120 meters per second through hot combustion gases positioned into an open end The paper first discusses the relativity between alternative combustion andNOx emissions by a test in dry cement kiln and a lot of case on fuel alternative The main findings of the study are that the use of RDF in cement kilns instead of coal or coke offers environmental benefits and reduce NOx emission The conclusion is that the NOx generation can probably be lower because of lower flame
