Fluidized Bed Furnace 

Kerone’s Fluidized Bed Furnaces utilize the remarkable heat and mass transfer properties of a fluidized bed — a suspension of solid particles in an upward flowing gas stream — to achieve extraordinarily uniform and rapid thermal treatment of components or materials immersed in the bed. The fluidized bed medium, typically consisting of fine refractory sand or ceramic particles, behaves like a fluid when the gas flow rate exceeds the minimum fluidization velocity, enveloping submerged workpieces from all directions with intimate gas-solid contact. This ensures heat transfer coefficients 5–10 times higher than conventional forced convection furnaces, resulting in very rapid heating rates, exceptional temperature uniformity across complex geometries, and highly efficient heat treatment processes. Kerone’s Fluidized Bed Furnaces are engineered for heat treatment, heat treatment scale-up, fluidized bed reactors, and specialized thermal processing applications.
