mechanical conveying equipment for boiler ashes and fly ash residue

Mechanical conveying equipment for boiler ashes and fly ash residue typically includes pneumatic systems, hydraulic systems, and various types of conveyors, such as submerged drag chains, belt conveyors, and bucket elevators, depending on the specific ash type and handling requirements.

Detailed Explanation:

Pneumatic Systems:

These systems use air to transport ash through pipes, suitable for both bottom ash and fly ash. They are commonly used in larger power plants for efficient and dust-free ash handling.

Hydraulic Systems:

These systems utilize water to transport ash, making them ideal for wet disposal of bottom ash and dewatering applications.

Conveyor Systems:

• Submerged Drag Chains: These conveyors are submerged in water to cool and transport hot bottom ash, often used in conjunction with dewatering slopes.

• Belt Conveyors: These are suitable for transporting ash over long distances, especially in tandem with other systems like silos or processing plants.

• Bucket Elevators: These are used to lift ash vertically, often in conjunction with other conveyors to reach storage or processing locations.

Other Equipment:

• Ash Storage Silos: Silos are essential for storing ash before further processing or disposal.

• Ash Processing Equipment: Equipment like crushers and screening devices may be used to prepare the ash for various applications, such as stabilization or disposal.

Types of Ash:

• Bottom Ash: This is the coarser, heavier ash that falls to the bottom of the combustion chamber.

• Fly Ash: This is the finer, lighter ash that is carried away in the flue gas.

Environmental Considerations:

• All ash handling systems are designed to be dust-free and environmentally friendly, often using enclosed systems and dust collection equipment.

• Hydraulic systems can also help with dust control and offer a more environmentally friendly option for ash disposal.
