Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon. Lignite has a low heating value and a high moisture content and is mainly used in electricity generation. The precursor to coal is peat. Peat is a soft, organic material consisting of partly decayed plant and mineral matter.

I assume you are talking about ash powder rather than coal dust from loading? I get very little coal dust from the buckets of coal I bring in since I am shoveling from the 5 gallon buckets directly into the stove and not dumping the bucket into a hopper. Also the coal I am bringing in is usually damp from being outside in the semi covered pile.

The most energyefficient drying process with ultrasound was found to be the sloping, ultrasonically vibrated trough. However, this process was limited to the use of an initial coal powder feed containing less than 10% moisture. For moisture contents above 10%, a dual drying system could be used. For example, the rotary kiln drier could be used ...

In 1840, a new method of drilling technology emerged: rotary drilling. This system relied on a man turning, by hand, a drill steel that would slowly work a hole into the rock. This system was originally only used in coal and very weak materials, as the pressure and speed of rotation were not fast enough for good penetration in hard rock.

Coal dust is a finepowdered form of coal which is created by the crushing, grinding, or pulverization of coal rock. Because of the brittle nature of coal, coal dust can be created by mining, transporting, or mechanically handling it.. Grinding or pulverizing coal to a dust form before combusting it improves the speed and efficiency of burning, which makes the coal easier to handle.
