INTRODUCTION TO FLUIDIZED BEDS
Turbulent Fluidization. Turbulent regime has the following features:-. High solid hold-ups (typically 25-35 % by volume). Limited axial mixing of gas. Suitable for exothermic and fast reactions. Good gas-solid contact and hence, favors reactant conversion. high gas flow-rates operation and good for isothermal operation.

New clinker formation process by the fluidized bed kiln …
The fluidized bed quenching cooler (FBQ) and the packed bed cooler (PBC) replace the clinker cooler [1]. One of the most important points of this system is the rapid temperature rise of raw materials in the SBK from approximately 850°C to 1350°C within a few seconds. It is achieved by the highly efficient and homogeneous burning conditions …

A comprehensive review of fluidized bed drying
Hot air fluidized bed drying (FBD) has an exclusive role in industrial progress due to ability in the relative ease of product handling, intensive mixing, and interfacial surface contact of the product with the drying medium (in the order of 3000–45,000 m 2 /m 3), and high heat capacity (∼10 6 J/m 3-K).

Coolers and Kiln Hoods
To cool the clinker, ambient air is blown via fans up through the porous floor of the cooler. The service environment of the cooler is extremely abrasive, subject to wide swings in temperature and alkali attack. Typically kiln feed used to make cement clinker enters the cooler at 1400°C and cools to about 150°C as it travels to the outlet.

Rotary Coolers
Rotary coolers work by tumbling material in a rotating drum in the presence of chilled or ambient air. The drum is set at a slight horizontal slope to allow gravity to assist in moving material through the drum. Lifting flights maximize heat transfer efficiency by lifting up material and dropping it through the chilled air as the drum rotates.
