Anthracite coal is available in a number of different grades or sizes as . buckwheat; egg; stove; chestnut; pea; broken; Each size is suited for different sizes of grates and firepots. Buckwheat coal is used in automatic coal firing burners in domestic, commercial and industrial stokers; Egg sized coal are used in large firepots.
Anthracite coal used for home heating purposes is uniformly sized to the following dimensions. The different sizes are used in different applications. The larger sizes consisting of stove, chestnut and pea are typically used in hand fired applications.
Anthracite, also known as hard coal, is a hard, compact variety of coal that has a submetallic has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals.. Anthracite is the most metamorphosed type of coal (but still represents lowgrade metamorphism), in which the carbon content is between 86% and 98%.
#0183;#32;Anthracite coal, mined from the planet''s oldest geological formations, has spent the longest time underground. The coal has been subjected to the most pressure and heat, making it the most compressed and hardest coal available. Hard coal contains greater potential to produce heat energy than softer, geologically quot;newerquot; coal.

There is a bit of a difference depending on which company produces the coal. But this is good scale of the sizes of coal as it is outlined and shown at the Anthracite Heritage Museum. From largest to smallest they are: Egg, Stove, Chestnut, Pea, Buckwheat, Rice and Barley. The Actual sizes in inches: Egg: 31/4quot; x 27/16quot; Stove: 27/16quot; x 15/8quot;
#0183;#32;For the energysize reduction process of mixtures, relation between specific energy and product t 10 is first discussed based on recorded and analyzed data as shown in Fig. of single grinding indicate that coking coal shows a higher product fineness if compared with that of anthracite coal for the same energy input.
And which size should you use on your railroad? Most of the coal mined in this country is a form called bituminous. The other less common form is anthracite, a hard energy dense form found only in isolated locations, most common in eastern Pennsylvania. Names for various sizes of bituminous coal include slack, stoker, nut, egg, lump, and run of
