Low NOx emission from coal-fired boilers can be realized by adopting the selective non-catalytic reduction (SNCR)technology on separators of large-scale circulating fluidized bed (CFB)boilers.On the basis of the SNCR flue gas denitrification system applied in Qinhuangdao Qinre Power Plant,the control system and strategy used in large scale CFB boilers were designed and developed.In addition,combining with the practical implementation,the effectiveness,stability and safety of the control strategy applied in this SNCR system was investigated.
