Abstract: A pollution control system having a blower located in a reduced temperature zone is disclosed. In one embodiment, the system comprises: an injection grid, a vaporizer, and a blower. The injection grid injects ammonia vapor into a flue gas stream. The ammonia vapor is created as the vaporizer vaporizes aqueous ammonia into a carrier medium.
