Introduction
The ZYLAB Fluidized Bed Calcination Furnace is an advanced thermal processing system designed for the calcination, decomposition, oxidation, and heat treatment of powder and fine particle materials. Based on fluidization technology, the furnace uses high-speed hot airflow to suspend materials in a fluidized “boiling” state, achieving extremely efficient gas-solid heat transfer and uniform thermal processing.
The system is widely used in laboratories, research institutes, pilot-scale production, and advanced material development applications.
Working Principle
The fluidized bed calcination furnace introduces powder or fine granular materials into a high-temperature airflow environment. The particles are suspended and fully dispersed by the gas stream, greatly increasing the contact area between gas and solids for rapid heat transfer and reaction efficiency.
The system mainly consists of:
- Multi-stage suspension preheater
- Fluidized calcination chamber
- Cyclone separator
- Cooling system
- Air supply and combustion system
Process Flow
Material Preheating
Materials pass through multi-stage cyclone preheaters and exchange heat counter-currently with high-temperature exhaust gas for rapid heating.
Fluidized Calcination
Preheated materials enter the calcination chamber and remain suspended in high-temperature airflow (600–1280°C), where decomposition, oxidation, and thermal reactions are completed efficiently.
Separation and Cooling
The reacted material is separated from exhaust gas through a cyclone separator and cooled to obtain the final product.
Heat Recovery
High-temperature exhaust gas is recycled back into the preheating system to maximize thermal efficiency and reduce energy consumption.
