Abstract
A method for reducing the content of nitrogen oxides in a flue gas stream, in which method the flue gas stream is taken from a thermal plant for the treatment of garbage, domestic waste, and/or residual materials similar to domestic waste, and is passed through a secondary treatment unit designed for selective, non-catalytic reduction, and then is subsequently passed through a scrubbing, absorption, or adsorption unit. According to the invention, an ozone injection into the flue gas stream is carried out downstream of the secondary treatment unit and upstream of the washing, absorption, or adsorption unit. The present invention also relates to a corresponding plant.
