Mark of coal

Grades of coal , their class size and characteristics:

A - B anthracite - brown T - A gas - long-flame M - bold K - Coke
OS - otoschenny caking SS - slabospekayuschiysya T - skinny

At the end of the brand name of coal can be an abbreviation OK (HC1, OK2), indicating the degree of oxidation.
Also, depending on the degree of enrichment of the coals are divided into concentrate, middlings and slimes.

The concentrates are generally used in boilers and generate electricity. Scrap usually go for the needs of industry. Of sludge briquettes can be produced and sold in the retail public for personal use.
Depending on the degree of coalification (metamorphism), there are brown coal, hard coal and anthracite. The lowest heat of combustion of brown coal in, and the highest - in anthracite.
The most favorable price ratio and the specific heat of combustion of fossil fuels have.

Coal grade A, D, and anthracite find their application, usually in the boiler, as they can burn without blowing.

Coal grade SS, OS, and T are used to generate electricity, as they have a higher heat of combustion, but combustion of this type of coal due to technical difficulties that can be justified only in case of need large quantities of coal.

The iron used is usually coal grade F, F for the production of steel and cast iron.
Markings on the coals can immediately identify their faction.
Designation:
P - (plate) to more than 100 mm - (big) 50-100 mm O - (walnut), 25-50 mm M - (small) 13-25 mm
C - (seeds) 6-13 mm W - (gum) 0-6 mm P - (Private) mine 0-200 mm, 0-300 mm career
Fraction of the coal grade is determined by the lower value of the smallest fraction and a larger value of the largest faction in the name of this brand of coal. For example, the fraction mark DKOM (K - 50-100 O - 25-50, M - 13-25) of 13-100 mm.
