The tubular dryer is among the techniques with the most industrial-scale experience. It has been widely used in Australia, Germany, and India in connection with lignite/brown coal briquetting. The plant consists, typically, of an inclined rotating shell with a tube heat exchanger (see Fig. 11.3 ).
For briquetting, coal with very little moisture is required. If moist lignite is used, it must be dried to a water content of around 15%. In general, tubular steam dryers or flue gas dryers are used in briquetting plants. In contrast, pelletizing is possible for a fine coal containing up to 30% of water (Conkle and Raghavan, 1992).
Reinforced and stiffened tubular shell for high strength. Seamless heat transfer tubes with flexible hose connections. Dimpled water jacket for increased cooling surface area. Heavy duty direct drive for smooth, consistent operation. Drive not susceptible to upset conditions. Heavy duty springs for an isolated design.
A steam heating conventional tubular dryer was used for the coal preparation and a natural gas steam reforming process was employed in the hydrogen production. The test facility for the new brown coal slurry dewatering process was designed for the capacity of 2 tons of maf coal equivalent a day.
Coal crusher grinder is of high-speed rotation so that complete of supply, crushing and wind transport characteristics in one. The pulverized coal is broken into the powder particles of the 0.03-0.06mm, and fed into the furnace with a pressure of 100-290 mm water column by the fan blade to form a full suspension combustion, achieve the best use.

The Air-Swept Tubular Dryer is a new concept in drying technology. Manufactured in the United States, it will process anything from low solids slurries to low moisture powders. The flow of material through the dryer is controlled so that the product may be a fine, dry powder or a moist granular material.
Charcoal/Coal is a desirable fuel because it produces a hot, long-lasting, fire. Combined with other materials and formed into uniform chunks, are called briquettes, it is popularly used for outdoor cooking and industrial purposes. Coal Briquette Dryer is a conveyorised machine .
The heating medium is used as classification parameter in this analysis. The first two concepts presented, the tubular dryer (1) and the fluidized-bed dryer (2) utilize steam as heating medium, while the two last systems, rotary (drum) dryer (3), and fan beater mill (4) utilize flue gas as a heating medium. 1.

Refined coal is the product of the application of a coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals and raising their calorific values. Coal refining or upgrading technologies are typically pre-combustion treatments and/or processes that alter the characteristics of a coal before it is burned.
The drying of lignite in the tubular dryer is an indirect drying, which is mainly performed through contact of the coal feed with the heating surface. ... Coal and carbonaceous materials react ...
