摘要：
A new process,NOx reduction with recycling flue gas and modifying coke breeze,was proposed. The effects of modified coke breeze and recycled flue gas on NOx reduction were investigated by sinter pot tests. The results show that the NOx reduction rate is over 10wt% in the sintering of modified coke breeze,the effects of the additives on NOx reduction are:CeO2>CaO>K2CO3. The NOx reduction rate increases with the amount of recycled flue gas,and is 22.35wt% in the sintering with recycling 30vol% of the flue gas. When 30vol% of the flue gas is recycled into the sintering of CeO2,CaO,and K2CO3 modified coke breeze,the NOx reduction rates are 36.10wt%,32.56wt%,and 32.17wt%,respectively.
