  • The collaborative disposal of industrial organic solid waste and increasingly strict NOx emission requirements have brought double challenges to the clean and stable operation of municipal waste incineration projects. The application effect of traditional exhaust gas recirculation technology has been affected, and it is difficult to meet the needs of the new situation, so it is urgent to develop more efficient swirling exhaust gas recirculation technology. This study analyzed the influence of applying swirling exhaust gas recirculation technology on furnace temperature control and NOx emissions of waste incinerators through numerical simulation and engineering experiments. The results showed that at under the exhaust gas recirculation ratio of 10%, the average temperature of the furnace decreased by about 20 ℃, reducing the risk of coking; swirling exhaust gas recirculation combined with SNCR technology can effectively control the NOx emission concentration below 80 mg/Nm3, reduce ammonia consumption by 35%, and reduce denitrification costs per ton of waste by 40.43%, achieving clean and stable incineration with significant economic benefits.
