What Is Equilibrated Moisture in coal ? Equilibrium moisture in coal refers to the moisture content that coal attains when it is stored in a specific environment and reaches a state of moisture balance with that environment. This state of moisture balance is achieved when the coal has been exposed to the same temperature and…
ASH FUSION TEMERATURE What Is ASH FUSION TEMPERATURE ? Ash Fusion Temperature (AFT) is an important property of coal, which is the temperature at which the ash residue from burning coal starts to soften and fuse together. The AFT is typically determined by heating a sample of coal in a high-temperature furnace, and observing the…
Gross Calorific Value By Using Bomb Calorimeter (LECO AC 500) The bomb calorimeter is used to analyze gross calorific value of any fuel. The amount of heat evolved when a unit weight of fuel is completely burnt and product of combustion cooled to normal Condition (with water Vapor condensed as a result). The heat contained in…
Coal Analysis Chemical analyses and testing of a coal sample are generally done off site in a laboratory. The main purpose of coal sample analysis is to determine the quality or rank of the coal along with its intrinsic characteristics. Furthermore this data will be used as the fundamental consideration for coal trading and its…
