A variety of problems occur during operation of the current SCR equipments
such as the large ammonia escape amount
high system resistance
ABS corrosion in air preheater and reduction in catalyst activity.Thus
by field test and catalyst performance analysis in a laboratory
performance of the SCR equipment in a 1 036 MW unit was comprehensively evaluated.After the diagnosis
suggestions like changing the SCR catalyst and transforming the ammonia spraying system were put forward.This performance diagnostic technology provides basis for analyzing the problems occur during SCR device running and formulating catalyst replacement strategy scientifically
which is also applicable for SCR equipments in other types of units.
