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.

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…

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…
