Formation of nitrogen oxides in the sintering of iron ore

Аннотация

If the emissions of nitrogen oxides NO_x in the sintering of iron ore may be curbed, the environmental and human impact of the process will be reduced. On the basis of experimental data, the NO_x formation in iron-ore sintering is analyzed. Data from an industrial sintering machine indicate that no more than half of the nitrogen in solid fuel is converted to NO_x. The NO_x content in the gases from sintering machines is proportional to the carbon-monoxide content. This finding may be used in predicting the NO_x emissions from sintering machines in calculations and simulations.
