Nozzles and engineered solutions for processes in air pollution control

Nozzles and engineered solutions for processes in air pollution control Precise cooling and conditioning of hot flue gases create stable outlet conditions for the safe and efficient operation of downstream plant components. Lechler is offering a wide range of engineered solutions to controll the outlet conditions of a gas cooling tower. The selective non-catalytic reduction (SNCR) is an industrial technique for NOx reduction. Twin-fluid or flat fan nozzle lances spray fine droplets of urea or aqueous ammonia directly into a furnace. With the selective catalytic reaction (SCR), achieving a high separation efficiency is possible only with the aid of a catalyst. Such a solution requires special precautions to keep the efficiency high and catalyst waste low. The reagent is added immediately before the catalyst using twin-fluid nozzle lances in a temperature window appropriate to the reaction.
