PRINCIPLE Fluidized bed furnaces employ an alloy retort filled with sand-like alumina particles. When a controlled stream of air or gas is passed upward through a distributor below the retort, the particles float on a cushion of the air /
Dryer suppliers often promote their particular technology. This has led to uncertainty among users selecting an optimal drying system. One common dilemma is the decision between drum dryers (rotary kiln dryers) or fluidized bed dryers (vibration fluidized bed dryers).
The fluidized-bed cement kiln reduces the raw material to a specific size for melting it into high quality cement, and then sinters the granulated raw material at a high temperature.

Circulating Fluidized Bed (CFB) Circulating fluidized beds (CFBs) are known to be compliant to current emission rate legislation without the capital expenditures of adding selective catalytic reduction (SCR) or flue-gas desulfurization (FGD).
The choice between a rotary dryer or fluid bed dryer is also a matter of energy. Fluid bed dryers work by fluidizing the material, which requires a high magnitude of air. Additionally, because it takes a certain amount of energy to fluidize a material, energy is not reduced when running at lower capacities.

The spouted bed kiln (SBK) acts as the granulating unit and the fluidized bed kiln (FBK) acts as the sintering unit that replaces the rotary kiln. The fluidized bed quenching cooler (FBQ) and the packed bed cooler (PBC) replace the clinker cooler  .
Coolers receive hot material (clinker) discharged from the kiln and cool it as it is conveyed to handling and storage systems. To cool the clinker, ambient air is blown via fans up through the porous floor of the cooler.
Fluidized bed combustors (FBC) are currently available in two varieties, known as bubbling and circulating fluidized bed combustors, and account for about 15% of the overall waste incineration capacity in Italy (Enea and Federambiente, 2006).
Rotary coolers and fluid bed coolers are each equipped to best handle different variables, as previously mentioned, with different industries favoring both units. However, most material processing issues are resolved prior to the cooling process, leaving rotary coolers and fluid bed coolers with limited material concerns to solve.

ii ABSTRACT EPA is revising hazardous air pollutant (HAP) emissions regulations for hazardous waste combustors, specifically incinerators, cement kilns, and lightweight aggregate kilns.
Carrier conventional fluid bed dryers are designed to dry and/or cool a variety of products without the aid of vibration. Our static fluid bed dryer systems pass a gas directly through a bed of solid material via a perforated plate, nozzles, or other fluidizing media which lifts and mixes the solids.
