Fluidized Bed Combustion FBC Boiler

“ (FBC) Fluidized bed combustion is a combustion technology used to burn solid fuels in steam boilers.” In Fluidized Bed Combustion Boiler technology When air or gas is passed through an inert bed of solid particles such as sand supported on a fine mesh or grid, the air initially will seek a path of least resistance and pass upward through the sand.

Fluidized Bed Combustion

The evaporator tubes of boiler are directly immersed in the fluidized bed and the tubes, being in direct contact with the burning coal particles, produce very high heat transfer rates. Because of this, the unit size is reduced to a great extent, and also produces combustion with very high efficiency. Types of Fluidized Bed Combustion (FBC)

Fluidized Bed Combustors for Biomass Boilers

Fluidized-bed boilers are the most common type of boilers recommended for biomass fuel. The fuel is suspended by an upward flow of combustion air through a bed of hot, inert particles, allowing oxygen to reach the combustible material more readily.

What are fluidized bed boilers?

A fluidized bed creates conditions suitable for the uniform combustion of fuel throughout its volume, which means, as a final result, more perfect fuel burn-up (high efficiency of a fluidized bed boiler) at lower combustion temperatures and whilst reducing the production of harmful waste gases at the same time.
