摘要:
In electric filters with a negative corona, an aerosol is formed in the entrance area if ammonia is present in the flue gas, reducing the separation performance of the filter. To avoid this, spray electrodes and separation electrodes provided in the entrance area of the filter are wired so that a positive corona forms there. In sections downstream in the flow direction of the gas, spray electrodes and separation electrodes are wired such that a negative corona forms there.
