A process for the removal of oxides of nitrogen from the exhaust gases from incandescent lamps - and pickling lines, as well as incandescent lamps - and pickling line, in particular for stainless steel - - warm or cold rolled strip

摘要

A process for the removal of oxides of nitrogen from the exhaust gases from incandescent lamps - and pickling lines provides that the exhaust gases of the pickling section and heated by means of selective catalytic reduction (scr) are denitrified.In order to secure maintaining the lowest nox - values in the exhaust gas to achieve with the smallest possible expenditure, the exhaust gases of the pickling section (3) in front of the selective catalytic reduction (9) heat from the exhaust gases of the annealing furnace (1) is supplied to.
