Classification of coal based on volatile matter and cooking power of clean material Sponsored Links Coal is a readily combustible rock containing more than 50 percent by weight of carbonaceous material formed from compaction and indurations of variously altered plant remains similar to those in peat.
This test method also concerns the designation of a coal sample as to its upper (nominal topsize) and lower (nominal bottomsize) limiting sizes for the purpose of characterizing the material for further processing or for commercial purposes. This is covered in Part B of this test method.
After pregrading, coal samples with different sizes (> mm, – mm, and l < mm) were prepared and subjected to microwave preprocessing at a power density of × 10 4 W/m 3 for 2 min. Next, different grades of coal samples, indicated by G1, G2, and G3, were fed to the air jet pulverization and grading system for experiments.
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. Usually with beds more than 16 inches deep; Stove sized coal is used for heating buildings etc. Mostly replaced with gas or oil

SGS global teams of chemists and experts use a range of coal analytical calculations and indexes to arrive at the calorific values, total hydrogen, Coke Reactivity Index (CRI) and Coke Strength after Reaction (CSR) of your coal sample.
A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

What are the different types of coal? PDF version. The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock.
