Hamada Boiler. PRINCIPLE OF FLUIDIZATION. When a bed of fine particles, for example sand, is subjected to an upward stream of air, the particles become suspended as the airflow reaches a certain velocity. This condition is referred to as the minimum fluidizing velocity and it varies according to the particle size and the depth of the bed.

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.
