Dry Ash Handling Conveyor for Power Plants

Dry Ash Handling Conveyor for Power Plants

Dry ash handling conveyors are advanced systems designed to handle bottom ash and fly ash from power plants without the use of water, making them an environmentally friendly and energy-efficient solution. These systems are widely adopted in modern waste-to-energy plants, coal-fired power plants, and biomass power plants to meet strict environmental standards, conserve water, and improve ash quality for reuse.

Key Features of Dry Ash Handling Conveyors

1. Water-Free Operation:
   • Eliminates the need for water quenching and transport, conserving resources and avoiding water treatment processes.
2. High-Temperature Resistance:
   • Designed to handle ash at high temperatures (up to 800°C or more) directly from the furnace or boiler.
3. Dust-Free Design:
   • Enclosed systems prevent the release of ash dust, ensuring a clean and safe environment for workers and surrounding areas.
4. Modular and Compact:
   • Flexible designs can be customized to fit plant layouts and capacity requirements.
5. Energy Efficiency:
   • Uses mechanical conveying methods that minimize energy consumption compared to pneumatic systems.

Types of Dry Ash Handling Conveyors

1. Belt Conveyors:
   • Ideal for transporting large quantities of ash over long distances.
   • Equipped with heat-resistant belts to handle hot ash.
2. Screw Conveyors:
   • Suitable for short distances and controlled discharge rates.
   • Handles abrasive materials with minimal spillage.
3. Drag Chain Conveyors:
   • Common for high-capacity ash transport.
   • Consists of a chain and flight system that drags ash through an enclosed trough.
4. Vibratory Conveyors:
   • Use vibrations to move ash along a trough.
   • Best for small-scale operations or where precise control of ash movement is required.
5. Pneumatic Conveyors (Dry):
   • Utilizes air pressure to transport ash through pipes to silos or disposal points.
   • Ideal for long-distance transport in a completely enclosed manner.

How a Dry Ash Handling Conveyor Works

1. Ash Collection:
   • Hot ash is discharged from the boiler or furnace into a dry conveyor system.
2. Ash Transport:
   • The ash is moved along the conveyor using mechanical or pneumatic systems.
   • If needed, ash is cooled using ambient or forced air during transport.
3. Ash Storage:
   • The ash is delivered to storage silos, bins, or directly to transportation vehicles for disposal or recycling.

Advantages of Dry Ash Handling Conveyors

1. Water Conservation:
   • Eliminates water usage, addressing regulatory concerns and reducing operational costs.
2. Improved Ash Quality:
   • Dry ash is better suited for recycling in construction materials such as cement, bricks, and road aggregates.
3. Low Maintenance Requirements:
   • Dry systems eliminate corrosion and wear caused by water, leading to longer equipment life.
4. Environmental Compliance:
   • Enclosed designs prevent dust and air pollution, meeting stringent emissions regulations.
5. Energy Savings:
   • Dry systems are more energy-efficient compared to wet ash systems.

Applications of Dry Ash Handling Systems

1. Waste-to-Energy Plants:
   • Handles bottom ash and fly ash generated from incinerating waste.
2. Coal-Fired Power Plants:
   • Transports bottom ash and fly ash generated during coal combustion.
3. Biomass Power Plants:
   • Removes ash from biomass fuel sources like wood chips, agricultural waste, and pellets.
4. Industrial Boilers:
   • Manages slag and ash in high-temperature industrial processes.

Bottom Ash Handling Systems

BG Series Scraper Conveyor Overview

1.BG series scraper conveyor is a continuous conveying mechanical equipment for conveying powdery and small granular dry materials, which can be arranged horizontally or inclined at a small angle.
2.The equipment has the advantages of simple structure, stable and reliable operation, long conveying distance, good sealing performance, low wear and low noise.
3.Its process layout is flexible, and it can add and unload materials at multiple points and realize quantitative conveying.
4.Because the shell is a fully enclosed structure, it has outstanding advantages in improving the operating conditions of workers and preventing environmental pollution when dealing with toxic, flying, explosive and high-temperature materials.

BG Series Scraper Conveyor Structural Features and Working Principle

1.BG series scraper conveyor is composed of head part, middle trough body, tail part, scraper conveyor chain, driving device and installation bolster beam.
2.Fully enclosed casing, no material leakage when the equipment is running; the conveying chain is made of high-quality alloy die forgings after heat treatment, which is strong and wear-resistant; the inlet and outlet of the equipment and the conveying length can be flexibly designed and arranged according to the process requirements.
3.The material enters the bottom of the tank evenly through the feeding port of the equipment, and is continuously and evenly transported from the feeding port to the discharge port by the load-bearing scraper conveyor chain that runs continuously from the tail to the machine head. It can realize multi-point feeding and multi-point unloading.
4.The tail of the machine is equipped with a screw adjustment device to adjust the tightness of the conveyor chain to ensure that it is always in a moderately tensioned state during operation, so that the equipment is in a stable operating state.
5.BG series scraper conveyors are suitable for conveying powdery and small granular dry materials with small abrasiveness and small accumulation specific gravity, such as steelmaking dust and dust from bag filter.
6.The BG series scraper conveyor produced by our company can be selected when conveying powdery, small particle and small block dry materials with high abrasiveness and high bulk density.
