Introduction. Fossil fuels including fuel oil, natural gas, and coal mostly meet the world's energy needs (Hagen and Robinson Citation 2002).With regards to fossil fuels, coal is the most plentiful energy source, accounting for 40% of global energy (Mathews et al. Citation 2009).Coal provides 77% of South Africa's energy needs, 95% of this energy …

In this study, a Turkish lignite (the Konya-Ilgın lignite) was used to study its drying characteristics in a fixed-bed dryer. The drying experiments were conducted with coarse lignite particles ...

calculation. If the throughput of the dryer is 60 kg of wet product per hour, drying it from 55% moisture to 10% moisture, the heat requirement is: 60 kg of wet product contains 60 x 0.55 kg water = 33 kg moisture and 60 x (1 - 0.55) = 27 kg bone-dry product. As the final product contains 10% moisture, the moisture in the product is 27/9 = 3 kg ...

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.

Basic Combustion Calculations Note: Some e xcess air is used to compensate for less -than -ideal situations, and to help assure that adequate oxygen is available for complete combustion.
