In order to protect environment and reduce operation cost of the boiler, Taiyuan Steel carried out low-NOx transformation to its No.2 300MW boiler unit adopting stereo-staged strengthened combustion-stabilizing and high-efficiency horizontal concentrated pulverized coal technology. Test and operation results after the transformation showed that NOx emissions from the furnace have greatly reduced and the boiler efficiency, combustible content in fly ash and CO emission index were all significantly improved.
