HOT TRANSPORT CONVEYOR (HTC) SYSTEM
Hot Transport Conveyor
The Hot Transport Conveyor (HTC) System is a specialized ash handling system designed for the efficient transportation of high-temperature ash or slag directly from the boiler or furnace to designated collection points, such as silos or processing areas. It is a dry ash handling solution, eliminating the need for water-based quenching systems and addressing environmental concerns such as water usage and pollution.
Key Features of the HTC System:
- High-Temperature Operation:
- The HTC system is capable of handling ash at extremely high temperatures, typically ranging from 300°C to 800°C, depending on the boiler’s operating conditions.
- Robust Construction:
- Built with heat-resistant materials, the HTC system ensures long-term reliability and durability, even in harsh environments.
- Dust Control:
- The conveyor is designed to minimize dust emissions through enclosed structures and integrated sealing systems, ensuring compliance with environmental regulations.
- Air Cooling Mechanism:
- Some HTC systems use ambient or forced air for cooling the ash as it is transported, ensuring safe handling and reducing the need for additional cooling systems.
- Continuous Operation:
- Provides uninterrupted ash transport, allowing for higher operational efficiency and minimal downtime for maintenance.
- Energy Efficiency:
- The system optimizes energy usage by utilizing mechanical components such as chain conveyors or screw conveyors that require minimal power.
Working Principle:
- Ash Discharge:
- High-temperature ash or slag is discharged from the boiler’s ash hopper into the HTC system.
- Ash Transport:
- The ash is conveyed via a chain conveyor, belt conveyor, or screw conveyor, depending on the design. The conveyor is enclosed to prevent heat and dust from escaping.
- Cooling:
- As the ash moves along the conveyor, it undergoes air cooling through ambient or forced air mechanisms, reducing its temperature before further processing.
- Ash Collection:
- The ash is delivered to the designated collection point, such as a silo, bin, or transportation vehicle, for disposal or recycling.
Advantages of the HTC System:
- Water-Free Operation:
- Unlike submerged or wet ash handling systems, the HTC eliminates water usage, conserving resources and reducing wastewater treatment requirements.
- Environmental Compliance:
- Dust-free operation and the absence of water pollution make it easier to meet environmental regulations.
- Lower Maintenance Costs:
- Without water and corrosion-related issues, the system requires less frequent maintenance and repairs.
- Reuse Potential:
- Dry ash is more suitable for recycling and reuse in applications such as cement production or road construction.
- Space Efficiency:
- Compact and modular design allows for easy integration into existing plant layouts.
Applications:
- Waste-to-Energy Plants: Transporting high-temperature bottom ash.
- Coal-Fired Power Plants: Handling boiler bottom ash or clinker.
- Biomass Power Plants: Transporting ash from wood chips or other biomass fuel sources.
- Industrial Furnaces: Handling slag and residues from industrial processes.
Why Use HTC Systems?
Hot Transport Conveyor systems are an innovative solution for modern power plants aiming to enhance efficiency, reduce environmental impact, and improve operational reliability. They are particularly beneficial for plants that require continuous ash removal and wish to minimize water usage while handling high-temperature ash safely.

Ash extracting conveyors of different systems belong to the product range and delivery program. These products are for both the extraction of combustion chamber ash and the transport of all other ash residues of coal-fired steam generators and waste incineration plants. To ensure high availability of the plants conveying components have been developed, which guarantee reliable operation and are economically justifiable with regard to power requirements, operation, maintenance, repair and investment costs.

Advantage:
1. Solid structure. It can withstand the impact, collision, smashing, pressure and other external forces of coal, gangue or other materials.
2. It can meet the needs of uneven, bending and moving of the floor of the coal mining face, and can bear the bending in the vertical or horizontal direction.
3. Low fuselage for easy installation.
4. It can also be used as the track for shearer operation.
5. It can run in reverse to facilitate the handling of bottom chain accidents.
6. It can be used as the fulcrum of the front section of the hydraulic support.
7. The utility model has the advantages of simple structure and can be fed or unloaded at any point on the conveying length.
8. The enclosure is sealed, which can prevent dust flying and polluting the environment when transporting materials.
9. When there is no casing at the tail and the scraper is inserted into the pile, it can be taken and transported by itself.
