The coal analysis and calorific value is determined and reported as on air dried basis (adb) this adb analysis is corrected to the actual conditions in the field to the extent of the difference in the moisture content since there is a lag between the sampling and the lab analysis, some moisture can evaporate to avoid this error, coal is. Coal analysis techniques are specific analytical methods designed to measure the particular physical and chemical properties of coals these methods are used primarily to determine the suitability of coal for coking, power generation or for iron ore smelting in the manufacture of steel. Our coal, minerals and materials analysis instruments range covers coal,coke, iron ores, cement, mineral & material testing for serving industries and labs.
- The calorific value of power plant coal is the amount of potential energy in coal that can be converted into actual heating ability calorific value of coal can be determined either by calculation from chemical analysis or by burning a sample in calorimeter.
- Coal testing and analysis provides the basis of the coal’s evaluation, in terms of usage, environmental implications and value based on its properties, coal can be classified by rank, from lowest to highest, into the categories of lignite, sub-bituminous, bituminous and anthracite.
- This analysis directly measures the carbon, hydrogen, nitrogen and sulfur in a coal sample the moisture and ash from the proximate analysis are also included oxygen content is calculated by finding the difference in the same way as the fixed carbon is in the proximate analysis.
