A Circulating Fluidized Bed (CFB) Boiler is a type of industrial boiler used to generate steam and electricity by burning solid fuels (like coal, biomass, or waste) in a highly efficient and low-emission way.

It is an advanced version of a fluidized bed combustion system, widely used in power plants.

🔥 Basic idea

In a CFB boiler, solid fuel particles are suspended in a fast-moving stream of air and combustion gases, making them behave like a “boiling fluid.” These particles circulate continuously through the system, improving combustion efficiency.
