A significant shift is underway in the management of boiler bottom ash within the power generation and heavy industrial sectors, marked by the increasing deployment of the advanced Dry Ash Conveyor technology. This system represents a substantial departure from traditional water-intensive slurry methods, offering a cleaner, more efficient, and entirely sealed approach to ash handling.
The core function of the Dry Ash Conveyor is integral to a modern dry ash handling system for boilers. In this process, incandescent bottom ash from the boiler grate falls through an ash hopper and a hydraulic cut-off gate, landing onto the scale plates of the conveyor. The system is engineered such that the Dry Ash Conveyor and the boiler bottom connection are fully sealed, preventing any fugitive dust emissions and maintaining boiler efficiency.
Operational reliability is a hallmark of this technology. The entire Dry Ash Conveyor is strategically divided into upper and lower layers. A variable frequency motor, located at the head of the unit, provides precise drive control. This motor utilizes a robust chain mechanism to drive the interconnected plates, which then convey the cooled ash material steadily toward the storage silo. This design is particularly suited for work conditions with large and fluctuating ash loads, ensuring consistent performance without bottlenecking.
Further enhancing its operational autonomy and maintenance profile, the typical Dry Ash Conveyor is equipped with an integrated automatic cleaning device that removes carryover material, and a tensioning device to maintain optimal chain slack. The move towards this technology is driven by its clear benefits: it conserves water, eliminates wastewater treatment needs, and the dry ash collected is easier to handle and more valuable for recycling in cement and construction applications, contributing to a more circular economy. This makes the modern Dry Ash Conveyor a cornerstone for plants aiming to boost their environmental stewardship and operational cost-effectiveness.
