Dry Ash Handling Conveyor for Power Plants

Dry Ash Handling Conveyor systems are increasingly favored in power plants, especially in waste-to-energy and coal-fired facilities, for their environmental and operational benefits. Unlike wet ash handling systems, which involve water submergence, dry systems handle and transport ash without water, providing efficiency in terms of energy savings, reduced water usage, and compliance with environmental regulations.

Key Features of Dry Ash Handling Conveyors:

1. Water-Free Operation:
   • Ash is collected and conveyed without the need for water quenching, which conserves water and eliminates wastewater treatment.
2. High-Temperature Tolerance:
   • These systems are designed to handle ash at high temperatures directly from the boiler discharge.
3. Sealed Enclosure:
   • The conveyor is typically sealed to prevent ash leakage and dust emissions, ensuring compliance with strict environmental standards.
4. Efficient Cooling Mechanisms:
   • Some systems incorporate air-cooling or indirect heat exchangers to cool the ash during conveying, enabling safe handling.
5. Low Maintenance Requirements:
   • With fewer components exposed to water or corrosion, these systems require less maintenance compared to wet ash systems.
6. Compact and Modular Design:
   • The conveyor can be customized to fit into tight spaces and accommodate different plant layouts.

Types of Dry Ash Handling Conveyors:

1. Mechanical Conveyors:
   • Screw Conveyors: Ideal for small ash volumes and short transport distances.
   • Drag Chain Conveyors: Best suited for handling large ash volumes over moderate distances.
   • Belt Conveyors: Common for long-distance transport with minimal energy consumption.
2. Pneumatic Conveyors:
   • Use high-pressure air to transport ash through pipes to a storage silo or disposal site. These are preferred for long distances and enclosed transport.
3. Vibratory Conveyors:
   • Use vibrations to move ash along a trough. These are typically used for smaller systems and specific applications.

Working Principle:

1. Ash is discharged from the boiler or furnace at high temperatures.
2. Depending on the system, ash may be cooled using ambient air, heat exchangers, or indirect methods.
3. The conveyor transports the ash to a collection silo or directly to disposal or processing units, such as recycling for construction material.

Advantages of Dry Ash Handling Systems:

1. Water Conservation:
   • Eliminates the use of water, saving resources and complying with water-related environmental regulations.
2. Energy Efficiency:
   • No need for pumps or water recirculation systems.
3. Reduced Environmental Impact:
   • Minimizes the risk of contamination from ash-water runoff.
4. Improved Ash Quality:
   • Dry ash is often more suitable for reuse (e.g., as aggregate in construction).
5. Lower Maintenance Costs:
   • No corrosion from water and fewer moving parts exposed to wear.

Applications:

• Waste-to-energy plants
• Coal-fired power plants
• Biomass and industrial boilers
• Cement and lime production facilities

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.
