How Circulating Fluidized Bed Boilers Work?

Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler. At the bottom of the boiler furnace there is a bed of inert material.

Biomass combustion in fluidized bed boilers: Potential

Furthermore, these alkali compounds, typically in herbaceous biomass can also lead to agglomeration problems in fluidized beds. In order to avoid biomass-ash agglomeration problems, fluidized beds may be forced to run at lower than optimal temperatures and thus decreasing the combustion efficiency.

Fluidized bed combustion - Wikipedia

2019-9-27 · Fluidized Bed Combustion. Atmospheric fluidized beds use limestone or dolomite to capture sulfur released by the combustion of coal. Jets of air suspend the mixture of sorbent and burning coal during combustion, converting the mixture into a suspension of red-hot particles that flow like a fluid. These boilers operate at atmospheric pressure.
