Abstract: From the structural point of view, the characteristics of the platetype catalyst were analyzed. Taking the catalyst selection and design of a DeNOx project as the example, the suitability of the platetype catalyst to the high dust and high arsenic flue gas condition in DeNOx system of coalfired power plants was expounded.

Key words: high dust and high arsenic coal-fired flue gas, flue gas denitration (DeNOx), plate-type catalyst, suitability
