    Definition technology which reduces NOx emissions by injecting urea into the furnace flue gas in an appropriate temperature window, NOx reacting with urea to form harmless nitrogen, water, and a small amount of CO Reference "Based on: IEA Clean Coal Centre. Selective non-catalytic reduction (SNCR) for NOx control. (4.2.2020)"
    Comment This process takes place only in a narrow 200°C (390°F) temperature range, below which NH3 (ammonia) is formed and above which NOx emission levels actually increase.
