An industrial hygiene survey of fluidized bed combustion technology was conducted. The purpose of the survey was to characterize current or potential occupational health problems of fluidized bed combustion processes (SIC-4961). Air sampling was conducted for 18 chemical agents at three facilities utilizing fluidized bed boilers. Noise and ionizing radiation exposures were also evaluated.

Fluidized Bed Boiler - an overview | ScienceDirect Topics

The fluidized bed boiler is gaining in popularity and has overtaken the grate-fired boiler in biofuel power generation applications. The principle is very simple: air is blown through a bed of sand and fuel particles at a velocity that is sufficient to suspend the particles on the airstream but not able to lift them permanently out of the bed, that is, 1–3 m s −1 at 800–900 °C.

The adsorption agent is fluidized due to the fluidization gas flowing from the bottom to the top through the grate bar bottoms 10 (upper fluidized layer 35 and lower fluidized layer 36) and through an overflow channel 27 reaches the lower fluidized layer 36.

Understanding Refractory Failure—A New Perspective

Refractory has always been an integral part of steam-generating boilers. In the steam-generating industry, refractory materials are used for filling gaps and openings to help keep the fire inside the fire box, for lining ash hoppers (wet and dry) that collect ash and slag, and for the protection of lower furnace wall tubes inside fluidized bed, cyclone-fired, or refuse-derived fired boilers.
