Inner Mongolia Ordos Fly Ash Closed Conveying Case

In the Inner Mongolia Ordos region, fly ash handling presents significant logistical and environmental challenges for coal-fired power plants and industrial facilities. This case study examines how a tailored closed conveying system addressed these issues, ensuring efficient, safe, and sustainable material transport.

Case Overview

A large-scale coal power plant in Ordos faced increasing pressure to manage its fly ash output while minimizing dust emissions and operational downtime. The plant's existing open conveying methods led to frequent spills, high maintenance costs, and regulatory compliance risks. The plant engaged a specialized material handling solution provider (referred to as Company X) to design and implement a closed conveying system.

Customer Pain Points

• Environmental Compliance: Open fly ash transport generated airborne dust, violating local air quality standards and incurring fines.
• Operational Inefficiency: Frequent blockages and equipment wear caused unscheduled shutdowns, reducing plant availability.
• High Maintenance Costs: Abrasive fly ash particles accelerated component degradation, requiring frequent replacement of belts, rollers, and seals.
• Safety Hazards: Dust accumulation posed health risks to workers and created explosion potential in confined areas.

Product Advantages – Proposed Solution

Company X deployed a fully enclosed, pressurized conveying system designed specifically for fine, abrasive fly ash. The system integrated the following key features:

• Sealed Pipeline Network: A continuous, airtight conduit eliminated dust leakage and reduced fugitive emissions to near zero.
• Low-Speed Airslide Technology: Gentle pneumatic transport minimized particle degradation and equipment abrasion, extending service life.
• Automated Flow Control: Real-time sensors adjusted air pressure and material velocity, preventing blockages and ensuring steady throughput.
• Modular Design: Easy-to-replace wear liners and quick-access inspection ports simplified maintenance and reduced downtime.

After installation, the closed system achieved a 40% reduction in maintenance costs, eliminated dust-related compliance violations, and improved overall plant reliability. The solution demonstrated that closed conveying is a practical, cost-effective choice for high-volume fly ash handling in arid, windy environments like Ordos.
