摘要
Abstract
The low NOX AireJet, DAR-4Z burners are used and OFA nozzles in dual air zone are installed in low NOX retrofit of opposed firing boilers of 300 MW units. Through test and adjustment , when OFA box damper opening is between 50% and 100%, the NOX emission can be reduced. To fully open the secondary air bushing at OFA nozzle, damper of the central air, reduce the angle of the external secondary air blade and box damper opening of standby burner can decrease NOX emission. For the air distribution for boiler op-eration, when the air box damper opens by 50% to 100%, the ventilation door of AireJet burner opens by 35%and that of DRB-4Z burner opens by 45%to 55%, the NOX emission is optimal. In case of 300 MW op-erating condition, NOX emission at economizer outlet decreases from 500~700 mg/m3 before the retrofit to 280 mg/m3 or the below.关键词
