Mar 06, 2015 Determining the Gross Calorific Value in Coal. Coal, as it is commonly known, is a solid fossil hydrocarbon fuel material. The gross calorific value of coal is frequently used when determining the total calorific value for a specific amount of coal for fuel value purposes or when establishing the rank of classification of the coal material.

Coal is generally analysed to determine its physical, chemical, thermal, mechanical properties like size consist, proximate values, ultimate values, calorific value and HGI. Calorific Value (CV) is an important thermal property of coal which indicates the amount of heat energy that

The calorific values of the individual combustible in the fuel are given below: Goutel suggested the following formula from calculating the higher calorific value when the percentage proxi mate analysis of fuel is known. The formula is, cal. value = 343.3 x fixed carbon % + α x % volatile matter kJ/kg.

as 17.38 and Indian coal as 47.1. Briquetting: An Alternative Source of Energy. 4.5 Calorific Value The calorific values of the each briquette is determined by using Bomb Calorimeter and the values from the results obtained for P W100 as 18,929kj/kg,, P WO100 as 19,351kj/kg, P W50 as 17,894kj/kg, P W20 as 18,118kj/kg, P WO20 as 18,095kj/kg, A

determined by carrying out proximate analysis and gross calorific value (GCV) by using bomb calorimetry. The results for intrinsic properties and the gross calorific value are given in table 1. Correlation analysis was carried out to analyze the individual effect of moisture, volatile matter, ash and fixed carbon on the gross calorific value (GCV).
