Directing against the problems may be faced in application of high dust selective catalytic reduction(SCR) denitrification facility

analysis has been carried out

and recommendations being put forward from aspects of reasonably designing the SCR reactor and selecting the suitable catalyst

especially the deactivation problem of catalyst must considered for coals in China due to potential ash deposition resulting from activity of the catalyst and high CaO content in the fly ash being pointed out.At the same time of carrying out theoretical analysis

taking the SCR denitrification facilities of 600 MW unit in Taishan Power Plant and in Yangcheng Power Plant as examples

some problems needing to be considered in the engineering projects have been explained.
