  • Rotary dryer

    2021-12-2u2002·u2002The rotary dryer is an important part of the charcoal machine production line. The airflow is in full contact with the material, and there are many mixing shafts and scrapers inside the equipment, which can promote the material to be pushed forward while drying. Since the length of the drum dryer is long, the material can be completely dried from beginning to end.

    In the proper temperature range, the injected ammonia or urea combines with nitrogen oxide to form water vapor and elemental nitrogen. SCR operates at a lower flue gas temperature than SNCR, and in addition uses a catalyst. Ammonia is injected into the flue gases when they are at about 600°F, and the mixture is passed through a catalyst bed.
