Lurgi CFB boilers used an external heat exchanger (FBHE), whereas Foster Wheeler CFB (before 1994) did not. The differences between these two systems can be seen in Fig. 16.3. Lurgi CFB boilers use a CFB loop with an external heat exchanger (FBHE) where about 20–60% of the total heat (excluding the boiler back pass) is absorbed.

How Circulating Fluidized Bed Boilers Work? - Bright Hub

In coal fired boilers the ash from the coal itself will be the makeup material. When firing bio fuels with very low ash content sand will be the makeup bed material. For high Sulphur coals Limestone addition to the bed material reduces SO2 emissions. CFBC uses crushed coal of 3 to 6 mm size. This requires only a crusher not a pulverizer.

FBC boilers and hence need not be pulverised as does in P.F. Boilers. No moving grate or burners in FBC boilers. Ash does not fuse at 900 DegC and hence soot blowers are not required. High combustion efficiency of fuel due to higher residence time and entire surface area of fuel in contact with air. 15 Stoker fired boiler 16 Stoker Fired Boilers

fFluidized Bed Combustion Minimum Fluidization Velocity:- Critical Velocity at which the pressure drop across the bed equals the weight of particles per unit cross sectional area of bed. The bed is called incipiently fluidized at this velocity. With increase in air velocity the drag force by the fluid on particles exceeds their weight.
