SNCR / SCR Hybridized Denitrification Technology
---------------------------------------- -------------------------------------------------- -------------------------------------------------- -----------------------------------------  As shown above, can be done in the ammonia boiler discharge SCR while the boiler outlet of the SCR reactor is provided, while performing denitration. This is called SNCR / SCR mixed denitrification technology. If SNCR does have some of the denitration efficiency, the SCR catalyst can reduce the amount of, remove the SCR catalyst can be used as a spare for replacement of the catalyst. The above figure shows that the hybrid system can have more than 90% nitrogen oxide efficiency, falling from 898 to 998 °C (1650 to 1830 °F). Typical SNCR / SCR denitrification technology features 1. SNCR / SCR at the same time multi-point injection of ammonia, visual operating conditions to choose different points of different injection to improve efficiency. 2. 50 ~ 75% NO removal efficiency, <3% Ammonia Slip. 3. If the boiler space is large enough to make NH3 evenly distributed, you can cancel the SCR AIG. 4. SNCR only need to install NH3 nozzle, it can be installed in small space constraints. The following table shows the 320 MWE Hybrid system operation example (NSR = NH3 / NOx Molar Ratio)  |
