Fly ash introduction
 
Fly ash, also known as "pulverized fuel ash", is one of the coal combustion products, and is composed of the fine particles that are driven out of the boiler with the flue gases.

Fly ash is widely used in building materials, metallurgy, chemicals, coal, fertilizer industries to dry the materials with certain humidity or granularity.
Generally speaking fly ash dryer can dry the material from 30-40% humidity to 5%-10% humidity.

The Benefit of Pulverized Fuel Ash Dryer

♦ Combines flexibility with reliability resulting in a long service life. The rotary is also suitable for operation with a wide range of materials & particle sizes and can more readily accommodate 'upset' up-stream process conditions
♦ Co-current is suitable for materials with relatively high moistures and provides rapid evaporation without overheating the product. Counter-current has the greatest thermal gradient and helps achieve low product moistures
♦ Reduces equipment size and the associated capital and operating costs
♦ Promotes diffusion drying
♦ Relatively low fan power and low headroom
♦ Enables energy savings and system integration
