Consultation on palladium-based oxidizers
Thread Content
Recently, the auxiliary boiler in my facility was taken out of service; we cannot use it because the denitration unit is located inside that boiler. As a result, the denitration unit cannot function either. The nitrogen oxides in the flue gas are controlled solely by means of measures taken earlier in the process, with strict control over the oxygen content in the main air flow, in order to reduce nitrogen oxide levels. The oxidizer currently in use is a platinum-based one; there is consideration of using a palladium-based oxidizer. With control from the front end, the nitrogen oxide concentration is 200–300. To what extent can this concentration be reduced by using a palladium-based oxidizer, and what will be the effects? Is it necessary to add a large amount of it at the beginning? If any units are to be used, please discuss them among yourselves.
Given the current situation, it is recommended that the poster purchase a batch of palladium-based NOx-removing combustion promoters in the short term. Using palladium-based combustion promoters alone can be effective, but it will be difficult to reduce the value from 300 to below 200; if special restriction values are still applied, it will be impossible. The use of palladium-based oxidizers and off-market additives requires an increase to a certain level of stock. For palladium-based oxidizers alone, there is no need to establish a storage proportion.
