METHOD FOR RENEWED ACTIVATION OF HONEYCOMB-SHAPED CATALYST ELEMENTS FOR DENITRATING FLUE GASES |
摘要 |
The invention relates to a method for renewed activation of honeycomb-shaped catalyst elements for denitrating flue gases from fossil fuel-fired boiler plants, specially coal-fired boiler plants in large power stations. According to the invention, each catalyst element is mechanically cleaned using oil and water-free compressed air before mounting. Subsequently, each element is subjected to wet chemical cleaning using fully desalinated water and dried with oil and water-free compressed air. The inventive method enables the activity of used catalyst elements to be increased from less than 50 % to more 83 % of original activity.
