SCR 脱硝系统催化剂性能预测方法及实践
Prediction Method for Catalyst Performance of SCR Denitrification System and Its Practice
摘要
Abstract
Activity of catalyst of selective catalytic reduction (SCR)denitrification system may gradually reduce and its deni-trification performance may reduce as well due to influence of flying ash blocking,erosion,chemical poisoning,and so on after its running time delays,thus,it is needed to make prediction on performance of catalyst to guide increase or replace-ment of catalyst. Testing result of catalyst activity based on laboratory testing condition could not entirely reflect practical situation of the denitrification reactor,therefore,a method for correcting laboratory data by using field performance testing data of the denitrification system is proposed,which uses laboratory testing data of catalyst to know decreasing speed of cat-alyst activity while field testing data of the denitrification system to know practical denitrification performance of the reac-tor. Practice of prediction on catalyst performance of the denitrification system of some 1 000 MW unit is taken for an ex-ample to state scientific management on catalyst of SCR flue gas denitrification system.关键词
