Abstract:

The urea crystallization of the pyrolysis furnace in the selective catalytic reduction (SCR) denitration system of thermal power plant will lead to the failure of operattionof the whole denitration system. The case of the urea crystallization of the denitrification pyrolysis furnace of No.6 unit of Datang Luoyang Thermal Power Company Limited is taken as example to analyze the reason for the crystallization of urea in SCR urea pyrolysis furnace. The system design optimization scheme is proposed to effectively control the crystallization problem. It is hoped that the phenomenon of urea crystallization in the pyrolysis furnace can be effectively prevented and targeted countermeasures can be provided.
