Abstract: Abstract:The flue gas deNOx process of thermal power plant by selective catalytic reduction (SCR) method was introduced. Combining with the reformation project of the SCR flue gas deNOx system of a 600MW unit, the characteristics and process flow of the SCR flue gas deNOx system with urea used as denitrifying agent were analyzed. The concrete reformation scheme was put forward, which provides a reference for design of similar project.
