Optimization of NOx emission control based on high sulfur coal combustion

Combined with the operation of an 800MW supercritical boiler burning high sulfur coal, in order to control emission nitrogen oxides, optimization adjustment ammonia injection and NOx reduction based on combustion is proposed. According test inlet outlet denitration system under 800 MW condition, parameters NOx, O2, NH3, wind speed so at are tested, manual valve adjusted according results. After adjustment, distribution uniform, quantity reduced. flow field 500 conditions two uniform. The has achieved expected effect.
