摘要

•SNCR process was applied to the coke oven regenerator.•A new-type coke oven regenerator for cascade utilization of high-temperature waste heat was proposed.•The competitive reaction of NO reduction and NH3 oxidation restricted the NO conversion effect.•The mixing degree and effective contact of NH3 and NO were crucial for NO reduction.•A strategy to ensure the outlet NO/NH3 concentration was proposed.
