removal sulfur and ash at coal equipment

CHAPTER 3 Coal Preparation and Cleaning - Home - Springer

Most coal requires some preparation before use. Preparation may range from simply crushing to provide a size consist suitable for certain types of boilers to extensive size reduction and cleaning to remove sulfur and ash-forming mineral matter. At present,
