01 01 2014 A Chinese lignite coal Shenhua was used in the experiments and its proximate analysis and ultimate analysis data are presented in Table drying experiments were carried out in a fluidized bed dryer setup comprising a quartz reactor and electrically heated furnace and a temperature grams of as received sample with 224–355 μm particle size was placed in
a portion of fuel moisture from the lignite feedstock in a fluidized bed dryer FBD A moving fluidized bed coal dryer was selected for this project due to 1 its good heat and mass transfer characteristics which result in a much smaller dryer compared to a fixed bed design and 2 its high throughput which reduces number of required dryers.
Lignite dryer machine is a kind of rotary equipment for dewatering lignite coal Lignite dryer is also called brown coal dryer and wood coal drying machine which can realize continuous industrial and automatic operation It is designed specially targeted at lignite
Rotary lignite dryer adopts low temperature four stage drying techniques making the lignite moisture evaporate to less than 13 with the lignite quality being changeless The first stage drying area removes most moisture at high temperature of 400 centigrade degree on super wet condition to ensure the chemical component of lignite is the same and difficult to burn.
An experimental study was carried out for lignites of different places of origin Poland Greece Romania and Australia using a toroidal bed dryer The effect of the temperature on the drying efficiency including the loss of moisture content over time under fixed

since dryer coal is easier to convey this reduces maintenance costs and increases availability of the coal handling system Crushed coal is fed into the bunkers from where it flows by gravity to the coal feeders Dryer coal flows more readily and causes less feeder hopper bridging and plugging problems.
