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. 

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