What is Fluidised Bed Combustion or FBC?

Fluidised Bed Combustion is a method of burning solid fuels that suspends the fuel particles in an upward flow of air, resulting in a fluid-like state. This approach improves combustion efficiency and lowers emissions.

Types of FBC

There are two types of FBC –

• BFBC or Bubbling Fluidised Bed Combustion: Operates at a lower air velocity, separating solid and gas phases.
• CFBC or Circulating Fluidised Bed Combustion: Higher air velocity keeps particles in continual circulation, resulting in better combustion efficiency.

Advantages of FBC

Here are some merits of this process –

• It has high combustion efficiency.
• By this process, lower amount of pollutant emits.
• This process has flexibility to burn a wide range of fuels.

Applications of FBC

Here are some uses of this process –

• Used in Power Generation systems.
• Used in Waste to Energy plants.
• Used in industrial applications as well.
