Its calorific value is slightly less than that of the Bituminous coal. Its calorific value is in between 193000 to 26750 KJ / Kg. The moisture content is about 15 to 30%. It is brownish black in colour. These coals usually burned in the pulverized form. ... Coal preparation plant is as shown below in fig. 3.3.
Energy content or calorific value is the same as the heat of combustion, and can be calculated from thermodynamical values, or measured in a suitable apparatus:. A known amount of the fuel is burned at constant pressure and under standard conditions (0°C and 1 bar) and the heat released is captured in a known mass of water in a calorimeter. If the initial and final temperatures of the water ...

Abstract. In order to solve the production of refuse with higher calorific value using 2-product heavy medium cyclone in Umlalazi Coal Preparation Plant, South Africa, 3-product heavy medium cyclone was utilized in the retrofit and the separation performance was discussed in this paper.
The lower calorific value or Net calorific value (NCV) which supposes that the products of combustion contain the water of combustion to the vapor state. The heat contained in this water is not recovered. The higher calorific value or Gross calorific value (GCV) which supposes that the water of combustion is entirely condensed.
seam coal and as a result calorific value of coal directed to coal preparation plants is usually between 14.9 MJ/kg to 24.2 MJ/kg, and ash content in this coal is between 17% and 42%. High ash coal has to be and usually is washed.

Common coal analyses include: Ash fusion: determines how coal ash will behave when heated in an industrial furnace or boiler. Ash yield (part of proximate analysis): determines the amount of noncombustible material in a coal sample. Calorific value: determines the heating potential of coal; usually expressed in Btu per pound.
