Fluidized Bed Furnace

Fluidized Bed Furnace

A Fluidized Bed Furnace creates a fluid-like state by suspending solid particles in a uniform stream of gas, ensuring excellent heat transfer, precise temperature control, and homogeneous processing. Designed for applications ranging from ore beneficiation to thermal decomposition and combustion studies, this furnace is a versatile platform for industrial and research use. 

How It Works

The furnace operates by introducing gas or air through a distributor plate at the base of a chamber filled with granular materials (e.g., sand, metal powders, or catalysts). This upward gas flow fluidizes the bed, turning the solid particles into a highly uniform, dynamic heat transfer medium. The result is an ideal environment for consistent temperature distribution, rapid heating, and excellent mixing. 

  • Operating Temperature: 750°C to 1600°C 
  • Heating Method: 
    • Lab-Scale: Electrically heated external walls 
    • Industrial Scale: Compatible with solid, liquid, and gaseous fuels
  • Gas Distribution: Precision-designed gas manifold and plenum for uniform pressure and flow 
  • Temperature Uniformity: Superior due to constant mixing of bed particles 
  • Control Interface: Optional PLC/HMI with data logging and recipe programming 
  • Ore Beneficiation – Refractory-grade iron ore processing 
  • Thermal Desorption & Pyrolysis – Treatment of waste or contaminated solids 
  • Calcination & Reduction – Of minerals and metal oxides 
  • Combustion Studies – Biomass, coal, or alternate fuels 
  • Material Coating & Surface Modification – Via vapor-solid interaction 
  • Waste Incineration & Gasification – With emission control 
  • Efficient Heat Transfer – Due to continuous particle movement 
  • Uniform Processing – Prevents hot spots or thermal gradients
