Abstract

Abstract: A plate-type catalyst for selective catalytic reduction (SCR) denitration system of a 600MW coal-fired power plant was studied. The denitration process characteristics and physical and chemical properties of the desulfurization process at different operating times were tested and analyzed. The results show that the content of active components of the catalyst decreases, and the content of alkali metals and alkaline earth metals increases. The deposition of fly ash and the wear of the catalyst during operation are the main reasons for the denitrification performance of the catalyst. Catalyst activity decreased by 21.6m/h after add installation in 2016. It was found that the catalyst in operation could not meet the operation requirements of the denitration equipment in 2018. Based on this, the catalyst replacement proposal was given, and the denitration catalyst was replaced for the operation of the power plant. Provide a reference and use this method as a life management mode for denitration catalysts.
