The utility model relates to a deNOx systems for CFB boiler, including urea supply unit, SNCR and SCR denitration unit include cyclone, with cyclone export the over heater that is linked together, with the over heater be linked together one-level economizer, with the one-level economizer that the one-level economizer be linked together, with one-level economizer between flue be linked together SCR catalyst supply part, urea supply unit respectively in cyclone entry flue one-level economizer entry flue be linked together. The utility model discloses can ensure that CFB boiler economy, safe realization NOx minimum is discharged under wide load operation within range, the burning inferior coal condition. |
