A White Paper by Delta Ducon 1. Executive Summary: The Imperative for Durable Material Handling The operational integrity of Circulating Fluid Bed (CFB) boiler systems, particularly those that utilize highly abrasive fuels like lignite, hinges on the reliability of their bulk material handling components. Standard rotary valves, often specified for these systems, are frequently inadequate for the extreme conditions they face, leading to premature wear, frequent maintenance, a

Power plants, particularly those reliant on coal and biomass, generate a significant amount of ash as a byproduct. This ash—primarily fly ash  and bottom ash —presents a major material handling challenge due to its highly abrasive nature, often-high temperatures, and the sheer volume produced. An efficient, reliable, and durable ash handling system is not just a matter of convenience; it is absolutely critical for maintaining continuous plant operations, ensuring worker safet

The mining and minerals processing industry is a proving ground for industrial equipment, demanding solutions that can endure the harshest conditions without faltering. When a major processor embarked on building a new Powder Processing facility, they faced a formidable challenge: handling diatomaceous earth (DE) . This fine, powdery, and highly abrasive material required a material handling solution that was not merely robust but a strategic, long-term investment for operati

Tired of Material Handling Headaches? Let's Talk Pneumatic Conveying! If you're in an industry that moves bulk materials – think powders, granules, pellets, or even chunky stuff – you know the challenges: dust, spills, wear and tear on equipment, and getting materials exactly where they need to go, efficiently and safely. That's where pneumatic conveying  comes in. At Delta Ducon, we live and breathe pneumatic conveying, designing systems that solve these exact problems. But

A White Paper by Delta Ducon 1. Executive Summary: The Critical Need for Engineered Solutions In industries that rely on the pneumatic or gravity-fed conveying of bulk materials—from mining and mineral processing to construction and manufacturing—the efficiency of material flow is paramount to operational success. However, when the materials are abrasive and heterogeneous, containing a mix of large rocks and fine powders, conventional material handling equipment often proves

1. The Challenge: Abrasive Fuel and Equipment Failure In 2007, a 305 Megawatt Circulating Fluid Bed Boiler (CFB) plant near College Station, Texas, faced a significant operational challenge. The plant's primary fuel, lignite, a brown coal and the lowest-ranking type of coal, was causing continuous problems for its material handling equipment. Lignite, a material that is abrasive, sticky, and flammable, was being metered into the boiler via a gravimetric feeder. A critical com

Delta Ducon, a trusted partner in the heavy industrial sector, is proud to announce its attendance and exhibition at the 2025 Western Cement Summit  in Newport Beach, CA, on September 10th and 11th. This premier event is a critical gathering for leaders, manufacturers, and specialists from the cement and concrete industries across the Western U.S., offering a unique platform to explore the dynamics shaping our industry's future. For over a century, Delta Ducon has provided cu

A Case Study by Delta Ducon 1. Executive Summary: The Challenge of Abrasive Marble Dust In the demanding world of mineral processing, the phrase "rotary valve wear" is often synonymous with costly downtime, frequent maintenance, and frustratingly short equipment life. A prominent marble processing plant in the southern United States faced this exact predicament. Their process, which involved pneumatically conveying highly abrasive marble dust, was hampered by the rapid failur

Introduction: The Painful Problem of Passing Stones In the world of industrial manufacturing, a seemingly simple problem can quickly become a costly and frustrating ordeal. For National Gypsum's Burlington, New Jersey plant, the challenge was to efficiently discharge a mix of gypsum rocks and fine powder from their 300-ton capacity storage silos onto a conveyor belt. The material—composed of brittle, chalky gypsum rocks up to 2 inches in diameter and extremely fine powder—pre

You've invested in a pneumatic conveying system designed for the brutal reality of high-abrasive materials. You've chosen components engineered for resilience. But what happens when the unexpected occurs? When a critical part eventually reaches the end of its formidable life? When you need expert guidance, fast, to keep your production moving? This is where the true value of your supplier is revealed, and this is precisely where Delta Ducon delivers an unparalleled level of c

For industries dealing with abrasive bulk materials like cement, mining ores, minerals, steel byproducts, and power generation fuels, efficient and reliable material handling is paramount. At the heart of many pneumatic conveying systems lies the diverter valve, a critical component responsible for directing the flow of these materials to different destinations. However, many facilities still rely on older style diverter valves that are prone to wear, leakage, and frequent ma
