Shanxi Lvliang Fly Ash Closed Pneumatic Conveying System

The Shanxi Lvliang Fly Ash Closed Pneumatic Conveying System developed by headpowder is a comprehensive engineered solution designed for the efficient and environmentally responsible handling of fly ash in large-scale industrial operations. This system addresses the unique challenges faced by thermal power plants and cement facilities in the Lvliang region, where high volumes of fly ash require reliable transport without compromising air quality or workplace safety.

Project Overview

A major industrial facility in Lvliang, Shanxi Province, was struggling with the management of fly ash generated from coal-fired power generation. The existing open handling methods led to significant dust emissions, high maintenance costs, and frequent system blockages. headpowder was engaged to design and install a closed pneumatic conveying system that could replace the outdated mechanical conveyors and manual handling processes.

Customer Challenges

The client faced several pressing issues: severe fugitive dust during transfer leading to environmental non-compliance, high energy consumption from aging bucket elevators and screw conveyors, frequent equipment wear due to abrasive fly ash particles, and the inability to scale the system for increased production volumes. Additionally, manual intervention was required to clear blockages, creating safety risks for operators. The existing layout also occupied excessive floor space, limiting future expansion.

Solution & Product Advantages

headpowder provided a custom-designed closed pneumatic conveying system that fully enclosed the fly ash transport process from storage silo to end-use point. The system utilizes negative (vacuum) and positive pressure conveying stages to move fly ash efficiently over distances of up to 500 meters. Key advantages include:

• Zero dust emission through fully sealed pipelines and automatic valve sealing technology.
• Reduced energy consumption by as much as 30% compared to mechanical conveyors, achieved through optimized pipe diameter and air velocity control.
• Minimal maintenance requirement due to wear-resistant ceramic-lined elbows and modular component design.
• Automated control with PLC-based monitoring and remote access, eliminating the need for round-the-clock operator presence.
• Compact footprint that frees up valuable floor space for other process equipment.

After commissioning, the system demonstrated reliable performance with a conveying capacity of 60 tons per hour, consistent ash temperature stability, and a notable decrease in the facility's overall carbon footprint. The closed-loop design also met local environmental regulations without additional dust collection equipment.
