| 摘 要： | 将含有NH_3、CO、空气和氮气的混合气体通过高温反应器,模拟考察不完全再生FCC装置CO锅炉中NH_3的转化及NO_x的生成规律。结果表明:NH_3在975℃的温度下,生成NO_x的比例为30%~45%;CO锅炉入口的氧含量越高,NO_x生成比例也越高;体系中CO的存在,对NO_x的生成有一定的抑制作用,降低温度、提高CO浓度可明显降低NO_x排放。

SIMULATION STUDY OF NH3 TRANSFORMATION IN CO BOILER OF INCOMPLETE REGENERATION FCCU |
| |
| Abstract: | A mixed gas containing NH3, CO, N2 and air with different ratios was used for the simulation study of NH3 transformation at high temperature in CO boiler of incomplete regeneration FCC unit. The results show that nearly 30%-45% NH3 are transformed into NOx at 975 ℃, and the yield of NOx increases with the increase of O2 concentration at outlet of the boiler. The existence of CO in the mixed gas decreases the generation of NOx. The higher combustor temperature and the higher CO concentration can reduce NOx emission significantly. |
