SNCR or Selective Non-Catalytic Reduction Selective non-catalytic reduction is a method to reduce NOx without using a catalyst in the temperature range of 850 to 1100°C. The most commonly used drugs are ammonia and urea. In general, SNCR denitrification efficiency can reach 25% to 40% for large coal-fired units and up to 80% for small units. Because the method is greatly affected by the size of the boiler structure, it is mostly used as a supplementary treatment means of low-NOx combustion technology. Its low engineering cost, simple arrangement, small footprint, suitable for old plant transformation, new plants can be used in accordance with the boiler design.
