ROTOFeed

Clyde Pneumatic Conveying

The Clyde Pneumatic Conveying Rotofeed Injection technology is engineered to deliver highly precise and consistently controlled batch or continuous material injection directly into process environments, such as blast furnaces, power boilers, or similar applications.

Material is fed from a dispensing vessel via the Rotofeeder, powered by a variable-speed electric motor to regulate material flow into the injection pipeline.

Key Features:

Continuous or Batch Feed: Allows for both continuous or batch injection when equipped with a lock hopper.
Wide Control Over Feed Rate: Variable-speed motor enables a 10:1 system turndown or ramp-up for flexible control.
High Accuracy in Injection Rates: Achieves 1-2% accuracy by weight (gravimetric) with load cells, and 5-10% (volumetric) without load cells.

Benefits:

Exceptional Reliability: Built with proven components, ensuring dependable performance across diverse applications.
High Availability: Capable of over 3,000,000 cycles before major overhauls and 1,000,000 cycles for seal replacement.

Innovations for Reducing Acid Gas and Emissions Control

Since the 1980s, Delta Ducon has led the way in acid gas reduction through pioneering injection system technology. With hundreds of installations across industries like cement, mineral processing, and power, Delta Ducon’s systems effectively control pollutants like SO₂, SO₃, HCl, and mercury, providing a sustainable solution for environmental compliance. Utilizing materials such as activated carbon, hydrated lime, and sodium bicarbonate, these systems are easy to automate and install, offering a cost-effective option for businesses. As decarbonization becomes more essential, Delta Ducon remains a trusted partner for reducing emissions and supporting greener industrial operations.

Injection systems are used to control pollutants such as SO2 , SO3 ,HCl & Mercury. They are typically required to operate continuously, 24 hours per day, and are required to be reliable with zero to minimal down time. For this reason Delta Ducon equipment has been used in hundreds of injection systems. Our patented flow splitters and superior rotary valves are key components for injection systems.
