Abstract: The characteristics of three reductants, which are normally used in SCR flue gas denitration technology, are compared . Taking the 660 MW ultrasupercritical unit of a coalfired power plant as an example, the typical design of the ammonia station for large coalfired unit flue gas denitration equipment of which the liquid ammonia is used as reductant, was introduced, and the matters needing attentions in the ammonia station design were pointed out.
