What is boiler | Types of boiler | How does a steam boiler work

Jan 15, 2019 · There are three types of fluidized bed combustion boilers: 1. Atmospheric fluidized bed combustion system (AFBC) or Bubbling fluidized bed combustion (BFBC) AFBC is atmospheric fluidized bed combustion, where the furnace pressure is atmospheric pressure and velocity of fluidized air is in the range of 1.2 to 3.7 m/sec.

Bubbling Fluidized Bed - an overview | ScienceDirect Topics

5.5 Bubbling Fluidized-bed Combustion (BFBC) Boilers. In a bubbling fluidized-bed unit the fluidizing velocity is low (1.23.7 m/s). As a result, the particles are held mainly in a bed that has a depth of 1 m or so and has a definable surface, as already discussed in section 5.2. The combustion of heat is absorbed from the gas by the heat transfer tubes immersed in the bed and by a conventional water-wall surface.
