Heavy Veiling and Long Retention Time
Tarmac COAL Ash Dryers
Tarmac coal ash dryers are used for coal ash and bottom ash also. Our design and engineering staff will work with you. They consider the overall objective and the characteristics of your feed stock. Systems are designed for your project and at the same time meet or exceed all safety and electrical standards.
Tarmac dryers are designed to achieve higher yields and better product. We do this through heavy veiling and long retention time.
Tarmac International, Inc. provides Complete Systems to Dry, Screen, Crush, Classify, and Loadout COAL Ash.
Tarmac COAL Ash Dryers specifications
| DIA x Length | Production | Burner Size | Baghouse |
|---|---|---|---|
| 4.5’ x 30’ | 11 to 15 TPH | 10 BTU | 6,000 ACFM |
| 6.0’ x 30’ | 20 to 27 TPH | 15 BTU | 10,000 ACFM |
| 7.0’ x 30’ | 27 to 36 TPH | 25 BTU | 15,000 ACFM |
| 8.5’ x 50’ | 40 to 53 TPH | 30 BTU | 18,000 ACFM |
| 10’ x 50’ | 55 to 74 TPH | 45 BTU | 26,000 ACFM |
| 11’ x 60’ | 67 to 90 TPH | 55 BTU | 34,000 ACFM |
Assumes 20% moisture by total weight, 350 ft/min gas velocity, 250°f material discharge temperature, 60 lb/ft3, 500′ elevation.
Lower moisture levels will increase production, higher moistures will reduce production.
