Some fluid-bed dryers can handle light, powdery material like fly ash or granular materials like bottom ash. Other fluid-bed dryer designs can handle materials such as sludges, filter cakes and agglomerates that exhibit characteristics not normally conducive to fluid-bed processing. Such designs would be ideal for tailing-pond sediment.

Drying kinetic of Canadian lignite was studied in a pilot scale fluidized bed dryer using low temperature air (T≤70 ˚C). Minimum fluidization velocity was calculated and applied to the experiment. Samples showed poor fluidization ... Coal is an organic composition of mainly carbon, oxygen and hydrogen. It is a

The coal, in the form of coal particles, is fed into a drving chamber where the coal is suspended in a fluidized bed while being dried in an atmosphere of steam at a temperature too low to release oxygen but high enough to extract sulfur from the coal particles.

Some technological data for typical coal fluid-bed dryers for coal operating in the United States are given in Table 43.2. ... View in full-text. Context 4

Features. In the fluid bed, the hot air and the material vigorously mix each other to prompt heat transfer. Therefore, you are able to maintain the temperature in the bed uniformly and make infinite adjustments of the temperature, minimizing the decline in the quality and non-uniform drying. The large contact area of the material and the hot ...

1. . High energy efficiency – heat input generally less than 1,250 BTU/lb of water evaporated. 2. No blending or pre-conditioning of wet cake is necessary prior to enter the fluid bed dryer. Fluctuations in the percent solids of the incoming biosolids are accommodated by simple automation of operating procedures. 3. No large sealing surfaces to oxygen to enter during …
