Abstract

Abstract: Experiments were performed to investigate the problems of the existing combustion system and the SN-CR system of a CFB boiler before the ultra-low pollutants emission reconstruction,and made the plan.The practice of the project has proved that CFB boiler can meet the re-quirement of NOx ultra-low emission under the high or middle load after the reconstruction.But under the low load, especially the actual coal quality seriously deviated from the designed coal quality when there is still a large risk.

Key words: CFB, circulating fluidized bed, low-nitro? gen combustion, SNCR, ultra-low emission
