- Scope: Engineering, Procurement and Construction
Project Background
Engineering, procurement and construction of a 320-460 MTPH ENI Coal Flo® Thermal Dryer System.
The system is capable of handling 460 MTPH of J-Seam coal at 10.84% moisture and 320 MTPH of Upper Seam at 12.08% moisture. The process results in coal at 6% total moisture.
While evaporating approximately 26 MTPH of water, the system meets MWLAP requirements of 7.08 TSP per second and SO2 emissions of 5.6 GPS (based on the alkalinity of the water and sulfur content of the coal).
The coal to be dried is fed by conveyor into the feed control bin and discharged to the dryer bed with an automatically controlled gate.
On the dryer bed the coal is fluidized by the upward stream of hot gases and dried almost immediately then settles into the discharge hoppers.
As the drying gases are pulled through the coal bed, heat and velocity are quickly dissipated.
Gases leaving the drying chamber pass through cyclone dust collectors and a venture scrubber and mist eliminator for removal of coal particles and water droplets.
A fail-safe PLC control system with automatic and manual emergency sprays provides a maximum degree of safety.
