Advanced Control System for Optimized Oxygen Content Combustion Based on CO Measurement
In view of such problems as increasing generated nitrogen oxides,increasing pres-sure at inlet of denitrification and increasing injection amount of ammonia during denitrification due to long-term oxygen-enriched combustion by boilers in large power plants,the advanced con-trol system for optimized oxygen content combustion based on CO measurement was applied.After that,the oxygen content combustion by boiler could be optimized online in real time,and the set average oxygen content was reduced from 3.0％to 1.8％,which effectively alleviated the pressure of denitrification and saved the amount of ammonia used,and therefore the purpose of energy sav-ing and emission reduction was achieved.
