Discharge Device
Discharge Device
A reliable discharge device is critical to the smooth operation of calciner plants to ensure a solid, constant inventory and assist in fluidizing solids. The discharge device is used to control the flow of hot alumina at the furnace seal pot.
Benefits
- Increased plant performance, availability, and safety
- Improved product quality
- Stabilized furnace inventory
- Longer life span
- Reduced maintenance
FEATURES
The discharge device is controlled by measuring furnace differential pressure and operates as a variable cross-section valve. We developed the first CFB calciner in the early 1970s. We have designed and constructed 51 calciners with continuous developments and innovation in material selection and design over 5 decades. We possess a proven track record with project execution excellence globally, most projects delivered as EPC contracts.
Our latest-generation discharge device is embedded in the rich history of Metso Outotec alumina calcination and has been developed to reflect a state-of-art Metso Outotec design.
Features
- Enhanced material selection for lance tip, lance tube, and nozzle bricks, in alignment with plant temperature and customer preferences
- Optimization of Cv value for a variable cross-section
- Improved actuator control using the latest pneumatic actuator and positioner design
- Compatible with existing communications protocol (4-20 ma + Hart, Fieldbus, etc.) refining feedback
- New center purging air design embedded in the lance tube, eliminating manual purging lance, or can be used in combination with manual purging lance
- Incorporation of the latest machine safety regulations
The new discharge device has shown increased plant performance, availability, and safety. Product quality and homogeneity are improved by stabilizing the furnace inventory. The longer life span of the device and components saves costs and reduces maintenance with a fast and easy exchange of the device.
The additional features and longer life span of the device and components save costs and reduce the maintenance period with a fast and easy exchange of the new device.
