SNCR (Selective Non-Catalytic Reduction) is a low-cost denitrification technology. This technology utilises the furnace as a reactor, spraying a reducing agent (commonly ammonia water or urea solution in industrial applications) into the furnace at temperatures ranging from 900 to 1100°C, where it reacts with the NOx in the flue gas to produce nitrogen and water, thereby achieving the removal of NOx from the flue gas.

SCR flue gas denitrification technology

SCR flue gas denitrification technology Product Details SCR (Selective Catalytic Reduction) is a well-established flue gas denitrification technology. A denitrification unit typically comprises an ammonia generation system, an ammonia/flue gas mixing unit, a reactor, a catalyst and a control system. It is situated between the boiler economiser and the air preheater, with a reaction temperature…

SNCR/SCR hybrid denitrification process

SNCR/SCR hybrid denitrification process Product Details Basic Principles SNCR/SCR hybrid denitrification technology is an integrated process, rather than simply the combined use of SCR and SNCR processes. It is a novel, highly efficient and technically mature improvement on the SCR process, developed by building upon the SCR process and combining it with the cost-effective characteristics…
