Solid waste incineration requires the waste gas prevention and control processes.The removal of nitrogen oxides is an important component of waste gas treatment.This article analyzes the types and formation mechanism of nitrogen oxides in solid waste incineration gas,and discusses low nitrogen incineration technology and flue gas reduction and denitrification technology.Based on engineering practice,the paper compares and analyzes the technology characteristics,system composition,denitrification efficiency,and application cost of SNCR and SCR.From the perspective of construction and operation costs and denitrification efficiency,the SNCR process is suitable for low NOx content flue gas,while the SNCR+SCR combination process is suitable for high NOx content flue gas.
