Selective noncatalytic reduction definition

Selective noncatalytic reduction means a noncombustion control technology that destroys NOx by injecting a reducing agent (e.g., ammonia, urea, or cyanuric acid) into the flue gas, downstream of the combustion zone that converts NOx to molecular nitrogen, water, and when urea or cyanuric acid is used, to carbon dioxide.

Selective noncatalytic reduction or “SNCR” means a noncombustion technology that reduces NOx emissions without a catalyst by injecting a reducing agent (such as ammonia, urea or cyanuric acid) into the flue gas, downstream of the combustion zone; the injection of the reducing agent converts NOx to molecular nitrogen, water, and (if the reducing agent is urea or cyanuric acid) carbon dioxide (CO2).

  • Selective non-catalytic reduction involves the reaction of NOx with the reductant chemical at high temperature, thus, avoiding large capital costs for equipment and catalyst.
